In this video I show my experience with EEL Battery Company. The promises they made led me to order some of their cells for testing. Here is what I found.
The contact info for my preferred supplier is Jenny Wu. You can reach her at Jennywu896@gmail.com and please mention my channel. I will get a small commission on the sale. I have other videos on my testing of the cells from her.
@@terryward162 I use only the welded studs. I use 4nm for temporary connections and 6nm for the permanent connection. I have had no problems in hundreds of connections.
Ray, thank you so much for introducing me to this company. I have been dying for the opportunity to pay a premium price for substandard cells. Really this company’s wonderfully fluid warranty process only heightens the adventure that is DIY battery building. I cannot wait to start pouring my money down their drain. In all seriousness good to see you, happy early Fourth of July, glad you had a good vacation, and look forward to seeing the finished products. I’ve thoroughly enjoyed sharing the journey with you vicariously.
Ray, thanks for the honesty and information. I went through Jenny based on your input, and I couldn't be happier. Extremely timely responses and the batteries (32) CATL280 showed up in less than a week! Im opening the boxes now and so far they look absolutely perfect. I hope all 32 cells look as good as the first 6 Ive looked at. Thanks again. (I did tell Jenny that I learned about her services through your channel).
Open and honest from the get go as always Ray, that is why I am a subscriber. Thanks for posting, this was great information - I too have been "playing Chinese Roulet" ordering in batches of 16, waiting two months for the 'other shoe to drop', so far I have been happy with my purchases. I have worried over each order until the cells actually arrived safe and sound, and tested as advertized. Like you noted here, I have found that any company willing to talk to me, share test data, answer questions over an extended period of time, seems to help avoid any shady suppliers who don't have the patience. Knowing a company is actually a manufacturer (not just a reseller) also avoids some issues. Keep em coming: Your honesty and open approach is so refreshing on the net. Robert.
Thank you Ray for such honesty, in the long run it should undoubtedly pay dividends. When I saw the title I thought oh no, just bought a large order from Jenny. The spin on the story was superb! Looking forward to your videos on the BMS.
I recently built my first Battery bank and i used EEL batteries and i am happy so far with my results and in fact i just ordered 8 more to complete my twin 16s battery banks. Thanks for sharing and as always keep building!
I considered going through Eelbattery, but they showed me an estimate of $9,999 for shipping charges, LMAO. Im sure it was a glitch of some sort, but I decided to go elsewhere ultimatly.
It is amazing that a company would do that. No quality control there and no reliable customer satisfaction focus by the company. Awesome review. Rare to see that "Gut shot" honesty. Good job man! When somebody's gotta say it, say it. Thank you.
Ray, I very much appreciate you having as objective to share the knowledge rather than make money with TH-cam. It's something special. (Also, I think not many can afford to do things like this, because usually people have little money so if they are on TH-cam it can't not be about money, unfortunately, Unfortunately only few of us is comfortable enough economically in order to make TH-cam videos without money in mind but just to sharing the knowledge and such). I'd say don't feel strange about reviewing products and such. As long as you try your best to be honest about them - why not, you can review any product (in fact, maybe you "should" review products, maybe you are the right kind of person to do that, because in fact you'll be honest about them unlike most others that often are either paid to advertise a product, or they're trying to do the review in a way that those watching it will want to click their affiliate links (to Amazon, to Aliexpress) and buy that...).
Ray people trust you because you are straight up objective and show everything you are doing which is greatly appreciated. You take the time to explain what you are doing and why. The value of that information is off the charts. I have learned a ton of great information and could have found it no where else. The battery market seems to have divided into to groups. One, is the server rack battery approach and the other is building individual cells into a battery of your own configuration. Rolling your own is a big commitment to time, knowledge, and equipment for testing-charging, etc. As you say there is a much greater risk to buying individual cells. My goal is to build an off grid system for my house here in Florida. Buying individual cells and making my own batteries appeals to me, plus I can do it incrementally. I think it will be much more satisfying to roll my own system. To that end, if you find a good company you trust we will trust them also. I know that puts pressure on you, but since we know you are honest and wouldn't pull the wood over anyone eyes your best assessment is good enough. In the end you aren't responsible for the behavior of any company and you assessment can only be made from your experience with them. It is a sample of one so don't let that weight too much on you. Just be you, give us your best take and let the good times roll. :-) The batteries didn't test as you expected, it is what it is. Now we know. Thanks again for a great video. BTW I will be in the Great State of Texas next week visiting my sister who lives in Copperas Cove near Killeen.
Hi Ray, thanks again for your total honesty, I seriously don’t think you did anything bad or wrong in trying these cells. People do take notice of you especially as you speak the truth in volumes.
Hay Ray thanks a lot for this heads up, this is all very useful information, I live in the Irish republic an when I get my cells there is a 23% value added tax slapped on the price, so I really need to be sure they are going to be good cells, you have a great week. Michael.
Thanks ray for your quick reply, I was thinking of running a shed off it to start with but a small setup and when i have more conferred go bigger for the house , And the inverter needs to be Aust Plug 240v cheers and thanks.
Thanks for the video Ray. There's plenty of people on TH-cam whose channels are nothing but promotions for their affiliate links, it's nice to see someone focusing on getting out honest info. I've bought 64 cells from Docan in the last year, all perfect and in use working fantastic. It's a shame to see so many dealers spending their time trashing other vendors instead of improving their own game, it hurts the whole industry.
I like your style, tell the truth as you see it. I don't have a problem in you recommending kit when you do it this way, I don't have a problem in you getting any payments of any kind either. If its honest then its a benefit to your viewers. good job and thanks 👍
Thanks Ray for all I really appreciate your passion and your honesty . I am in Italy and I will contact JennyWu because I need (for now) 8 battery 280 . 👍Greetings
Thank you Ray for information and your time spent on making videos. I am not aware of any supplier warehouse in Australia, so I watch videos from "Off Grid Garage". In general I think Australia is left behind and is a bit of a dump site for chinese products - not just for batteries.
Hi, thanks for your video. In a German solar forum I found several reports identical to your experience or worse. Used cells, bulbous cells, damaged valves, low capacity and of course everyone should pay for the return shipping themselves.
They just need to be honest and accurate about the product, the buyer can make the decision if it suits their requirements. Thanks for you information.
Thanks for the frank and honest opinions expressed...... I would hazard to say that most people would be willing to pay more and not have to deal with bs from companies half a world away...... A bad experience lingers longer than a slight increase in cost......
Thanks Ray, for your time to show a great videos on solar a big eye opener and learnt a lot from this. Could you tell me what is a good inverter to look at to use.
Ray, I appreciate your hard and mental stressful work that you do for us. Don't let this false promise battery company get you down. This could have gotten a lot worse for everyone. I suspect that other battery companies will reaching out to you and asking you to sell there batteries. The reason that I watch, like and subscribe your channel is that I trust you. Even on our money, trust is a strong word. Thank for the video. Get back on that tractor 🚜buddy.
Dozens of companies have approached me. I usually just reply thanking them for their interest and state that at this time representing their product does not align with the core values of the channel.
@@RayBuildsCoolStuff wonder response Ray, "at this time." It's like you shut the door but left it unlocked. Meaning not interested at the moment but may change in the future. Take these approaches from these companies as a compliment on yourself and videos as how valuable you are. I'll be waiting for your next video brother, great job.
@@RayBuildsCoolStuff Chris is correct, when you say you like or trust something it gives it another layer of trust to your viewers. You did and do a good job of gaining that trust that in itself is a service to us as much as the how to aspect. Even more so as you don't do "reviews".
Ray, thanks for introducing us to Jenny. I always get a minor anxiety attack when sending a bunch of money to China but the order for 16 cells , from Houston, that I placed yesterday feels less stressful! lol. Jenny has been great to work with so far. Also, I made sure that she knows that you were responsible for me contacting her so hopefully that will help you a bit. The expected delivery is around 2 weeks, which is great. I will post an update when delivery occurs.
Did not expect to post an update this soon. I have my cells in hand after 4 days! Ordered and paid for them on Tuesday afternoon and today, Saturday they arrived from the Houston warehouse via UPS. Have only opened one box so far but cells are packed well, and look great. Another satisfied customer (assuming all cells are ok) . Jenny is building a very good reputation. She was helpful, responded quickly and knew exactly what was in the US inventory. I would buy through her again without hesitation. Ray, thanks for finding this lady for us!
@@weinvestcambiandomentalida2629 Sorry for slow response. Just saw your message today. I got my batteries very fast, about a week or so. Good quality, tracking etc. Would definitely buy from her again!
Hi Ray, This is my second day on your Channel. WHere In the Caribbean did you Scuba. I'm From Barbados and also looking into Ordering cells. For months I have been searching for a reliable source of Batteries. you can Guarantee I will be taking your advice
Hi from the UK....I bought 4 x 280ah Eve cells from EEL last October for my RV, they were $70 per cell plus the ddp shipping. They arrived on time and I'd describe the condition as excellent.....I have to say the experience i had with them was very good from start to finish. I'm now embarking on a 16 cell pack for home use and I've returned to EEL for these. Due to current world events the shipping has gone from 30 days to 50 but I'll report back when they arrive.
@@RayBuildsCoolStuff Hi Ray...I didn't as i don't have the equipment to test them ...Change of plan though, I'm using those 4 to add to another 12 for the house build as the RV isn't a priority...I can get another 4 as and when.
Thanks for your honesty. I am looking to buy these cells for my off grid home in Australia but the fear of paying for cells not fit for purpose has paralysed me. Sorry I can’t remember but have you put up the plans for your battery boxes? Also which bms are you using, can’t wait for the future videos. Keep up the good work. Congrats on your video editing.
Very true. People want honesty. I think a lot of DIY battery builder have been stung in the past. (including myself) When a customer is sending $1,000 or $10,000 to China they want some sort of quality track record.
Of course you are right, trust is the essential quality of a good relationship, difficult to gain, easy to lose. I tend to trust you, don't disappoint me :) François from France
Thanks for sharing this with us... that being said, can you comment on the implications of making a battery pack of cells that are less than 160Wh, but would be suitable for transport on a plane as carry on?
Close to what, a power plant! 😂 Seriously, sfk/product reviews, seems to me, not worth it to you! They're interesting to your viewers because of your integrity, thanks 🙏!
Hello Ray, Thanks for your very informative TH-cam videos. I took your advice and bought my batteries from Jenny Wu, they arrived in Canada in just over 2 months. Jenny was very helpful and always answered my questions promptly. The batteries are new and were a very good price with no extra fees, only what she quoted me.
I bought some other cell that had the test sheets in the high 280's but my tests came out similar to your. They all tested above 280 so I used them. They seem similar to to my other builds.
Did you ask the company how they performed their tests on their cells? If you have a different method to them, your tests would probably be different. A cell advertised as 280ah that gives you 280ah is in my view, a 280ah cell. I’ve just ordered 16 230ah prismatic for my first build from Docan Technologies and hope they are 230ah when tested but I’ll be testing them using their test procedure written down by the battery manufacturer. Love the channel by the way, very informative.
An unexpected outcame indeed though I think you could (in the future) buy some as John Doe and some as You. But since they are not as promised anyway it might not even matter. I'm going buy some from Jenny Wu soon. Thanks for sharing Ray
I had thoughts on insulating the bars while watching the last video. The only issue would be the mouting holes for the BMS leads but if you install those over the cell studs it would be a non issue.
Just keep this type of content going and you will be know as the most reliable solar thech on TH-cam to me you already are Btw Have you ever had any experience with docan power?
Jenny Wu works for docan power. I only trust Jenny though. The company is important but the person can make the big difference when it comes to honesty.
Just came across your channel! Sounds like a roller coaster ride! My question is on QR code how old was the batteries? 2 years or younger? I watch outback garage! You must have quite the array or water generator! Thanks
The cells are currently about 12 months old. About 9 months at time of testing. The LF280K series hasn’t been out for too long. It isn’t like Andy’s issues.
Be aware that EEL has sucked before in Germany due to under performing cells they had delivered. Still a lot of issues with suppliers like those with QSO or Quishou most recently published by andy from the off grid garage who had recorgnied bad comments about their delivery quality. His video is from 17th of June 2022 and he accused the supplier to have not solved issues with their battery deliveries. If I will buy I will try most likely Jenny Wu by mail and hope for the best cause on will prowse diy forum I did not find bad comments about her sales performance and delivery, quite the opposite as you had told us too.
14:02 I had same reaction when I heard it. It's not a common answer, I would say. In most cases you would've probably gotten an answer along the lines "please buy cells from us, we'll give you a coupon"
Hi again Ray. Thanks for the video. As always your honesty and integrity is very much appreciated. If I remember correctly the batteries from Docan ship from a warehouse in Texas. Am I correct? I’m planning on another set of batteries that will be funded, hopefully soon, with a sale of some property. As you are well aware of the geo-political nonsense that’s going on right now could make acquiring pretty dicey. I’m hoping that I can get the batteries before everything gets sideways. I’d be curious to know your thoughts on this as regards getting these batteries if things should go south. Best regards from Arizona. 🐢🌵
Email Jenny at jennywu896@gmail.com and she can answer your questions about pricing and availability. As far as geopolitical forecasts, I have been studying history most of my life. I am fascinated by watching it unfold in real time. I don't wish to make judgments except to say that it always seems scary to those that have fear no matter the decade. 50s, 60s, 70s, 80s, etc, all had their perceived evils that threatened our way of life, whatever that means. Go back further and it gets worse. I refuse to live in fear and I will continue to prepare for potential risks to my actual survival without placing too much emphasis on my ability to know what those are. The things that actually wreak havoc in our lives are usually things that we didn't see coming. In the meantime, my happiness is harmed by seeing others as evil and threatening and I am better served when I can be empathetic and spend my energy and time in service of the needs of others. Well my coffee needs a refill and I need to get moving. Good day and thanks for subscribing.
Thank you sir, your videos have been so helpful. Please sir, I need a video on the apparatus and equipment needed for battery testing and also a video on how to test batteries please sir. I will be so glad if you grant my request.
I have a video that shows the equipment I use for testing and charging my cells and the completed batteries. I also have a video showing how to use the equipment to top balance the cells and how I use the fully charged and top balanced battery to provide the energy for top balancing the next battery to conserve the energy. Enjoy sir!
Hi Ray I bought and received before your video to the same Seller you shown. I gonna do a discharge / charge discharge cycle 2,5v/3,65v for my 302ah batteries, if Real 302ah and let you know
Hi Ray I would to add something about this company. I bought 16s 302ah, and at this time 9 of 16 have been tested with the same charger as you. Results for the 9th cell : discharge : 287,00ah ; charge : 287,20ah, tested with cutoff at 1A. So Bad news for consumers who are interested to purchase 302ah or others because it is not what it is written into the title of the product. It is like I received a 280ah instead of a 302ah. So, people must be informed about this before buying to this company. Thanks to you Ray for your good job.
Hi Ray, I've just stumbled upon your channel while researching LF280K Batteries. Thank you so much for sharing your experiences with suppliers. I've been wanting to build a battery for my kayak and thought 4x LF280K Batteries would give me a much better battery than just buying the typical trolling motor batteries available. I'm considering a motor between 500w-1000w and want a battery that will give me plenty of range. Top speed is not my priority, rather long range. Do you think these 4x LF280K to give me 280AH 12V is a good choice? They work out more expensive than a 100AH trolling battery but much greater AH for the money. I'm not sure what the peak draw is on them at present, but will research further before buying. I have some experience with 18650 cells, but much prefer the LF280K for convenience of building packs. I'm also very interested in solar and energy storage, so I'll definitely be looking at more of your content and subscribing to your channel! Thanks for sharing the knowledge, and keep on building!
If you’re going to use the battery for a trolling motor you probably want a pre-built 12 V battery that is waterproof. I thought I had found a good kit for building this is a DIY but the supplier ended up being untrustworthy. I think most of the 12 V batteries that get built are built with 120 amp BMS that can pretty easily give you 100 A continuous. That will more than handle your 1000 W draw that you were considering. It would give you that rate for about 3 1/2 hours. I don’t think your trolling motor is going to use 1000 W though. It’s been a long time since I had a trolling motor but I’m pretty sure they draw a fraction of that. That’s more along the range of a circular saw.
@@RayBuildsCoolStuff Thanks for the reply Ray. Yes I'd be sealing the batteries in a waterproof box with circuit breaker and bms also. I have a sealed compartment inside my sit on top kayak which I think would be an ideal location for the battery. I would imagine I'd be using peak power very rarely, and maybe only in 10-15 second bursts.
@@barrymcmahon469 in case of a thermal event what is your plan for getting it out of your boat and how will it vent so it doesn’t build pressure? What is the plan for a capsize or sinking? How will you secure the cells during sudden movement so they don’t damage the terminals? These are the design questions I would be thinking about. In an open boat I would have a tether that allowed me to toss it overboard if a problem occurred. I have a friend that used to have a dive boat that did trips offshore. He had a table where people charged batteries while the boat was underway. He kept the table in his direct line of sight. Several times he saw batteries overheating while charging and toss them over board. A fire on board his boat was not something he was interested in being a part of. This chemistry is it known for starting fires but it does have a tremendous amount of energy that can be released if something goes wrong. These issues can be designed around but they do need to be addressed.
@@RayBuildsCoolStuff I know ventilation valves are available for marine battery boxes. I would plan to secure the batteries together with strong strapping and make sure they are a snug fit when inside battery box. I am a little unsure of fitting the battery inside the kayak for the exact reasons you've pointed out. The other option would be to have it strapped securely in the storage area where I can keep an eye on it and toss it over if any problems were to arise.
Did you find any grade A suppliers? I certainly got the impression you only found cheap grade F. What were your capacity tests? I see you saying that you tested your previous cells, but I don't remember seeing any results. I do notice Doncan is no longer advertising "grade A" EVE cells, rather "top grade".
Hi John, all we have is opinion. I will soon share mine in a video on the subject. I have shared test results from the suppliers I have used. I'll try to get a video out on this in the coming week. I have shared most of my thoughts in the comments section in the past but it is a poor way to communicate them. A comprehensive video will be better. Of course, it will be my experience and my opinion for that is all we have.
I have been buying and using 18650 cells for years now and one thing I found and suspect also applies to these cells is, the big commercial buyers will always get the "best" cells purely because of volume. That doesn't mean we get bad cells just that you need to keep in mind that Grade A is a valuable grade, grade B are still good batteries just not perfect, even grade C can be perfectly useable. As Ray pointed out in the video it's not so much the quality it's the promise of the quality. I'm sure he has plenty more to add due to his experience, waiting with baited breath.......😉
I waatched another TH-cam yesterday about how people are not buying raw materials to build stuff anymore. Also, I'm looking for a link to where you are getting those BMS boards and the display units.
Usually people that say it doesn’t make sense to DIY are including an affiliate link for a ready built battery that they are promoting. I buy directly from Seplos for their 48v BMS
Hi Ray, I need another help from you. As you know I have ordered 12 cells of 280Ah. Now I need to know which Made and sizes of battery cases I would need to order from Alababa. Thanks for your help

They just need to be honest and accurate about the product, the buyer can make the decision if it suits their requirements. Thanks for you information.
Thanks for the frank and honest opinions expressed......
I would hazard to say that most people would be willing to pay more and not have to deal with bs from companies half a world away......
A bad experience lingers longer than a slight increase in cost......
Great review!! Thanks.
Thanks Ray, for your time to show a great videos on solar a big eye opener and learnt a lot from this. Could you tell me what is a good inverter to look at to use.
What do you need the inverter to do?
Ray, I appreciate your hard and mental stressful work that you do for us. Don't let this false promise battery company get you down. This could have gotten a lot worse for everyone. I suspect that other battery companies will reaching out to you and asking you to sell there batteries. The reason that I watch, like and subscribe your channel is that I trust you. Even on our money, trust is a strong word. Thank for the video. Get back on that tractor 🚜buddy.
Dozens of companies have approached me. I usually just reply thanking them for their interest and state that at this time representing their product does not align with the core values of the channel.
@@RayBuildsCoolStuff wonder response Ray, "at this time." It's like you shut the door but left it unlocked. Meaning not interested at the moment but may change in the future. Take these approaches from these companies as a compliment on yourself and videos as how valuable you are. I'll be waiting for your next video brother, great job.
@@RayBuildsCoolStuff Chris is correct, when you say you like or trust something it gives it another layer of trust to your viewers. You did and do a good job of gaining that trust that in itself is a service to us as much as the how to aspect. Even more so as you don't do "reviews".
Ray, thanks for introducing us to Jenny. I always get a minor anxiety attack when sending a bunch of money to China but the order for 16 cells , from Houston, that I placed yesterday feels less stressful! lol. Jenny has been great to work with so far. Also, I made sure that she knows that you were responsible for me contacting her so hopefully that will help you a bit. The expected delivery is around 2 weeks, which is great. I will post an update when delivery occurs.
Did not expect to post an update this soon. I have my cells in hand after 4 days! Ordered and paid for them on Tuesday afternoon and today, Saturday they arrived from the Houston warehouse via UPS. Have only opened one box so far but cells are packed well, and look great. Another satisfied customer (assuming all cells are ok) . Jenny is building a very good reputation. She was helpful, responded quickly and knew exactly what was in the US inventory. I would buy through her again without hesitation. Ray, thanks for finding this lady for us!
Hello Phil Orton! I'm in Houston and I would like to hear your experience with Jeeny Wu and your order. Thank you!
@@weinvestcambiandomentalida2629 Sorry for slow response. Just saw your message today. I got my batteries very fast, about a week or so. Good quality, tracking etc. Would definitely buy from her again!
@@philorton1940 Thanks for the input.
@@philorton1940 Hey Phil about to deal with Jenny how did the cells turn out ? what did you pay in the end for the 16?
Hi Ray, This is my second day on your Channel. WHere In the Caribbean did you Scuba. I'm From Barbados and also looking into Ordering cells. For months I have been searching for a reliable source of Batteries. you can Guarantee I will be taking your advice
Great review! 👌Just subscribed to your channel!
Great vid Ray 👍
Thanks, honesty is a rare commodity. Much appreciate your work. ( Was just trying to visualize you as a politician) Couldn't see it?
Ray fails on all fronts: honesty, integrity and the will to help others (really) just doesn't look good on a politicians CV.
@@BenMitro sad but true. Ray is a star.
Hi from the UK....I bought 4 x 280ah Eve cells from EEL last October for my RV, they were $70 per cell plus the ddp shipping. They arrived on time and I'd describe the condition as excellent.....I have to say the experience i had with them was very good from start to finish. I'm now embarking on a 16 cell pack for home use and I've returned to EEL for these. Due to current world events the shipping has gone from 30 days to 50 but I'll report back when they arrive.
Did you test the capacity of the cells?
@@RayBuildsCoolStuff Hi Ray...I didn't as i don't have the equipment to test them ...Change of plan though, I'm using those 4 to add to another 12 for the house build as the RV isn't a priority...I can get another 4 as and when.
Great video!
Good job man. I enjoyed your other video first about buying Alibaba batteries. Now this one. Keep it up, I find you to be an honest person.
Thanks and thanks for subscribing. It really helps.
@@RayBuildsCoolStuff Yes, it does. I know how it goes.
Morning Ray, from Australia, hope the trip went well.
It did! Nice to see you again. I'm sorry for the lack of recent videos.
Thanks for your honesty. I am looking to buy these cells for my off grid home in Australia but the fear of paying for cells not fit for purpose has paralysed me. Sorry I can’t remember but have you put up the plans for your battery boxes? Also which bms are you using, can’t wait for the future videos. Keep up the good work. Congrats on your video editing.
I haven't bought any but there's a place in slacks Creek Brisbane called big wei that seems like a potential source.
You could contact Andy from YT offgridgarage to see what he does and his expereriences down under! Good luck!
I've checked their website and they are offering nice kit boxes for an honest price (without cells). Good chances that i will try one for my cells.
really appreciate this content

Very true. People want honesty. I think a lot of DIY battery builder have been stung in the past. (including myself) When a customer is sending $1,000 or $10,000 to China they want some sort of quality track record.
The more and more these bad sellers are exposed, they go out of business or improve to acceptable standards. Good video.
or open a new biz with new made-up employee names
@@wkrp10splayer19 unfortunately, that too. :(
Bravo !....Thanks
Of course you are right, trust is the essential quality of a good relationship, difficult to gain, easy to lose.
I tend to trust you, don't disappoint me :)
François from France
Thanks.
Good stuff Ray.
Thanks for sharing this with us... that being said, can you comment on the implications of making a battery pack of cells that are less than 160Wh, but would be suitable for transport on a plane as carry on?
Ray i think you might have the greatest hair on TH-cam
😂
Close to what, a power plant! 😂 Seriously, sfk/product reviews, seems to me, not worth it to you! They're interesting to your viewers because of your integrity, thanks 🙏!
Hello Ray, Thanks for your very informative TH-cam videos. I took your advice and bought my batteries from Jenny Wu, they arrived in Canada in just over 2 months. Jenny was very helpful and always answered my questions promptly. The batteries are new and
were a very good price with no extra fees, only what she quoted me.
That’s great Lisa. Best of luck with your project.
I bought some other cell that had the test sheets in the high 280's but my tests came out similar to your. They all tested above 280 so I used them. They seem similar to to my other builds.
Did you ask the company how they performed their tests on their cells? If you have a different method to them, your tests would probably be different. A cell advertised as 280ah that gives you 280ah is in my view, a 280ah cell. I’ve just ordered 16 230ah prismatic for my first build from Docan Technologies and hope they are 230ah when tested but I’ll be testing them using their test procedure written down by the battery manufacturer. Love the channel by the way, very informative.
thanks sir
Hey at least you were honest with everyone man that’s all I ask
9:22 they should add corner bumpers on that box. corners are easiest to damage.
good info
you been holding out on me ray ;)
Good review.. I buy from signature solar they are cheaper just add a bms with a texas warranty.... Keep it up brother.........
There prices are outrageous
An unexpected outcame indeed though I think you could (in the future) buy some as John Doe and some as You. But since they are not as promised anyway it might not even matter. I'm going buy some from Jenny Wu soon. Thanks for sharing Ray
Hi Ray, do you have link for the previous battery supplier. I needed to order battery. Thanks
I had thoughts on insulating the bars while watching the last video. The only issue would be the mouting holes for the BMS leads but if you install those over the cell studs it would be a non issue.
I find no point in insulating solid bus bars and heat dissipation will be better without insulation.
Just keep this type of content going and you will be know as the most reliable solar thech on TH-cam to me you already are
Btw Have you ever had any experience with docan power?
Jenny Wu works for docan power. I only trust Jenny though. The company is important but the person can make the big difference when it comes to honesty.
@@RayBuildsCoolStuff ok got it 👍 thanks for the reply a good honest person always makes the world of difference
Just came across your channel!
Sounds like a roller coaster ride!
My question is on QR code how old was the batteries? 2 years or younger?
I watch outback garage!
You must have quite the array or water generator!
Thanks
The cells are currently about 12 months old. About 9 months at time of testing. The LF280K series hasn’t been out for too long. It isn’t like Andy’s issues.
Be aware that EEL has sucked before in Germany due to under performing cells they had delivered. Still a lot of issues with suppliers like those with QSO or Quishou most recently published by andy from the off grid garage who had recorgnied bad comments about their delivery quality.
His video is from 17th of June 2022 and he accused the supplier to have not solved issues with their battery deliveries.
If I will buy I will try most likely Jenny Wu by mail and hope for the best cause on will prowse diy forum I did not find bad comments about her sales performance and delivery, quite the opposite as you had told us too.
Hi Ray, btw: my own Calibration of the buildin Current Sensor on Seplos BMS was successfull. I have the Steps posted in the "Dr Backe Forum"
14:02
I had same reaction when I heard it. It's not a common answer, I would say. In most cases you would've probably gotten an answer along the lines "please buy cells from us, we'll give you a coupon"
Hi again Ray. Thanks for the video. As always your honesty and integrity is very much appreciated. If I remember correctly the batteries from Docan ship from a warehouse in Texas. Am I correct? I’m planning on another set of batteries that will be funded, hopefully soon, with a sale of some property. As you are well aware of the geo-political nonsense that’s going on right now could make acquiring pretty dicey. I’m hoping that I can get the batteries before everything gets sideways. I’d be curious to know your thoughts on this as regards getting these batteries if things should go south. Best regards from Arizona. 🐢🌵
Email Jenny at jennywu896@gmail.com and she can answer your questions about pricing and availability. As far as geopolitical forecasts, I have been studying history most of my life. I am fascinated by watching it unfold in real time. I don't wish to make judgments except to say that it always seems scary to those that have fear no matter the decade. 50s, 60s, 70s, 80s, etc, all had their perceived evils that threatened our way of life, whatever that means. Go back further and it gets worse.
I refuse to live in fear and I will continue to prepare for potential risks to my actual survival without placing too much emphasis on my ability to know what those are. The things that actually wreak havoc in our lives are usually things that we didn't see coming.
In the meantime, my happiness is harmed by seeing others as evil and threatening and I am better served when I can be empathetic and spend my energy and time in service of the needs of others.
Well my coffee needs a refill and I need to get moving. Good day and thanks for subscribing.
@@RayBuildsCoolStuff Wow! That is an amazing answer. It really sets out how we should be approaching things. Thanks
Thank you sir, your videos have been so helpful. Please sir, I need a video on the apparatus and equipment needed for battery testing and also a video on how to test batteries please sir. I will be so glad if you grant my request.
I have a video that shows the equipment I use for testing and charging my cells and the completed batteries. I also have a video showing how to use the equipment to top balance the cells and how I use the fully charged and top balanced battery to provide the energy for top balancing the next battery to conserve the energy. Enjoy sir!

Hi Ray I bought and received before your video to the same Seller you shown. I gonna do a discharge / charge discharge cycle 2,5v/3,65v for my 302ah batteries, if Real 302ah and let you know
Hi Ray I would to add something about this company.
I bought 16s 302ah, and at this time 9 of 16 have been tested with the same charger as you.
Results for the 9th cell : discharge : 287,00ah ; charge : 287,20ah, tested with cutoff at 1A.
So Bad news for consumers who are interested to purchase 302ah or others because it is not what it is written into the title of the product. It is like I received a 280ah instead of a 302ah. So, people must be informed about this before buying to this company.
Thanks to you Ray for your good job.
Hi Ray, I've just stumbled upon your channel while researching LF280K Batteries.
Thank you so much for sharing your experiences with suppliers. I've been wanting to build a battery for my kayak and thought 4x LF280K Batteries would give me a much better battery than just buying the typical trolling motor batteries available. I'm considering a motor between 500w-1000w and want a battery that will give me plenty of range. Top speed is not my priority, rather long range. Do you think these 4x LF280K to give me 280AH 12V is a good choice? They work out more expensive than a 100AH trolling battery but much greater AH for the money. I'm not sure what the peak draw is on them at present, but will research further before buying.
I have some experience with 18650 cells, but much prefer the LF280K for convenience of building packs.
I'm also very interested in solar and energy storage, so I'll definitely be looking at more of your content and subscribing to your channel!
Thanks for sharing the knowledge, and keep on building!
If you’re going to use the battery for a trolling motor you probably want a pre-built 12 V battery that is waterproof. I thought I had found a good kit for building this is a DIY but the supplier ended up being untrustworthy. I think most of the 12 V batteries that get built are built with 120 amp BMS that can pretty easily give you 100 A continuous. That will more than handle your 1000 W draw that you were considering. It would give you that rate for about 3 1/2 hours. I don’t think your trolling motor is going to use 1000 W though. It’s been a long time since I had a trolling motor but I’m pretty sure they draw a fraction of that. That’s more along the range of a circular saw.
@@RayBuildsCoolStuff Thanks for the reply Ray.
Yes I'd be sealing the batteries in a waterproof box with circuit breaker and bms also. I have a sealed compartment inside my sit on top kayak which I think would be an ideal location for the battery. I would imagine I'd be using peak power very rarely, and maybe only in 10-15 second bursts.
@@barrymcmahon469 in case of a thermal event what is your plan for getting it out of your boat and how will it vent so it doesn’t build pressure? What is the plan for a capsize or sinking? How will you secure the cells during sudden movement so they don’t damage the terminals? These are the design questions I would be thinking about. In an open boat I would have a tether that allowed me to toss it overboard if a problem occurred. I have a friend that used to have a dive boat that did trips offshore. He had a table where people charged batteries while the boat was underway. He kept the table in his direct line of sight. Several times he saw batteries overheating while charging and toss them over board. A fire on board his boat was not something he was interested in being a part of. This chemistry is it known for starting fires but it does have a tremendous amount of energy that can be released if something goes wrong. These issues can be designed around but they do need to be addressed.
@@RayBuildsCoolStuff I know ventilation valves are available for marine battery boxes. I would plan to secure the batteries together with strong strapping and make sure they are a snug fit when inside battery box. I am a little unsure of fitting the battery inside the kayak for the exact reasons you've pointed out. The other option would be to have it strapped securely in the storage area where I can keep an eye on it and toss it over if any problems were to arise.
Did you find any grade A suppliers? I certainly got the impression you only found cheap grade F. What were your capacity tests? I see you saying that you tested your previous cells, but I don't remember seeing any results. I do notice Doncan is no longer advertising "grade A" EVE cells, rather "top grade".
Hi John, all we have is opinion. I will soon share mine in a video on the subject. I have shared test results from the suppliers I have used. I'll try to get a video out on this in the coming week. I have shared most of my thoughts in the comments section in the past but it is a poor way to communicate them. A comprehensive video will be better. Of course, it will be my experience and my opinion for that is all we have.
I have been buying and using 18650 cells for years now and one thing I found and suspect also applies to these cells is, the big commercial buyers will always get the "best" cells purely because of volume. That doesn't mean we get bad cells just that you need to keep in mind that Grade A is a valuable grade, grade B are still good batteries just not perfect, even grade C can be perfectly useable.
As Ray pointed out in the video it's not so much the quality it's the promise of the quality.
I'm sure he has plenty more to add due to his experience, waiting with baited breath.......😉
nice
Don’t call this a battery review, it’s really a seller review. As for myself I’ll stick with the one who has shown integrity Miss Wu
I waatched another TH-cam yesterday about how people are not buying raw materials to build stuff anymore. Also, I'm looking for a link to where you are getting those BMS boards and the display units.
Usually people that say it doesn’t make sense to DIY are including an affiliate link for a ready built battery that they are promoting. I buy directly from Seplos for their 48v BMS
👍👍
I' from Brazil and Jenny Wu don't send to my country. Do you recomend someone from aliexpress who could delivery to Brazil? Thank you
Thank you for the email so when I find a good deal Alibaba I can use that as a reference to make sure I'm getting a real supplier and not some copycat
Hi Ray, I need another help from you. As you know I have ordered 12 cells of 280Ah. Now I need to know which Made and sizes of battery cases I would need to order from Alababa. Thanks for your help
I don’t understand what you are asking.
