I did forget the most important part to add to the video - the Ice Pack test did NOT work! That's why I did use the duster and was able to trigger the low temp cut off. Unfortunately I missed this very important part! The cold temp cut off does work at a very low temperature and can already damage the battery - worst case. If you do not want to use the battery in a cold environment you will be fine - given the built quality ;-)
Much nicer teardown than my video. I did find the QR codes for cells and they said they were hithium prismatic cells but I'm not so sure. I was also impressed by the build quality
I like how they misspelled "Charing Voltage" on the label (LOL). Just ordered the 2-pack and hope they work with my charger/inverter setup. That thing is a lightweight compared to a 100ah or any of the lead acid 225ah batteries in my golf cart (LOL)...
Is there any protection between the cells? As the housing of the cells is connected with negative connection. If it's just the thin blue plastic in between, I would never have dared to use the battery
Seems there is no fibre board insulation between each individual cell, the thin blue shrink wrap is not sufficient especially when used in golf carts and battery is shaken around. Also an extra foam layer between each cell will give some room for a little bit expansion and keeps the cell pressure (kg/cm2) in check
I hate seeing a duster used for cold temperature testing. That will drop the temperature below -40°C. A medical gel pack is better for proper testing. To run a golf cart, you'll need a lot of surge power.
Good call. I hate to say it - but I did test it with the ice pack but with a different way of charging and it did NOT shut off. That's why I used the duster and it did work. I guess I messed this one up due to switching too many things back and forth at the same time... I knew there was something I forgot :/ Regarding the golf cart, where are you located again? ;-)
Some websites state max 50a discharge and the spec sheet on the battery state max. 100a cont. discharge. What is the rating of the BMS? Maximum 4 in parallel or are more allowed? Some websites states more then 4 is allowed when using a busbar, what is the correct info? Nice battery but specs are vague and battery seems to lack proper cell insulation to make them safe when rattled around.
Hi, I wanted to ask you for info on the parameters of the Epever6415an controller. What voltage of BOOST , FLOAT , MAX CHARGE VOLTAGE enter ? The manufacturer only declares the charge value at 58.40 v which is high by many users. Thank you very much.
Hi Tobi, I had to redo a comment I made earlier because apparently TH-cam didn't like me linking to Amazon. @ 3:43 you made a comment about max 4P (4 batteries in parallel) but on Amazon there is an image of the specs that states 'Parallel Unlimited'. So I'm confused now, which is correct? My common sense tells me that there should not be a limit on putting them in parallel, as long as the cables can handle whatever load you're applying.
Thanks for watching! That's what I don't like about those Chinese manufacturers. On Amazon they advertise one thing but the manual delivered with the battery tells a different story. I just checked and on the Specification Guide for this battery it states "Number of series and parallel connection" 4P1S. I just looked at Amazon and compared my screenshots. They added the new picture which says 1S2P. I'm with you why you want to add more. They even make this comment in the Amazon description: "When connected in parallel, the number of batteries is not limited so it is convenient for customers to use it." I usually want to listen to the manufacturer. But the form factor is so good to get 4 of those might work - without guarantee (make sure you have the appropriate cables as you pointed out.) Sorry to not give you an easy answer with this Chinese battery... Do you have a specific use case why you want 200AH in a 51.2V configuration?
@@tobisreallifeskillswithtobi Thanks for the quick response! I'm going to build a grid-tied Victron-based ESS with 8 of these batteries, combined with 2 Multiplus II 48/5000/70 inverters. I'm guessing since the batteries have no means of communicating with each other or a Cerbo GX, the risk of getting imbalances will be higher than with e.g. Pylontech batteries. But this also depends on how you wire them, generally hooking them up to a bus bar with equal length cables and/or diagonal connections is considered best practice to help minimize the risk of unbalanced loads. And of course it's also important to charge all batteries to the max individually before putting them in parallel. It's really annoying to get conflicting messages from the vendor and manufacturer, but I guess the best thing to do is perform some tests once I start building and put more than one shunt (e.g. SmartShunt) in place to monitor the batteries instead of just relying on their built-in BMS. I think the main issue will be enabling the ESS to 1. obtain the correct SOCs and 2. keep the battery bank balanced. Regarding the latter, it might be a better idea to assign each Multiplus II its own battery bank. So that would be 4 batteries each, which would also align with the 4P advice you cited.
Just to add. I bought the Eco 48v 50ah and they emailed me saying they are low on stock and asked me if I want settle for the blue version, they can ship it out right away. LOL, I knew exactly what they were talking about. I told them I know the blue version is the DC House brand and since all my stuff are Eco, I can wait for the Eco.
Thanks for watching and tricky question! I like the Bluetooth of the XRH. But I like and prefer the built quality of the DC house .. I experienced cell 1 of the XRH is not good and therefore I can't pull the full 100 Ah. I did not follow up yet since I use it as a test setup but encountered this. If you have a good shunt and good low temp protection on your end, go with DC house... I love the enclosure! I hope this helps!
With that 50A cut off you can't even drive a cart up a ramp to a trailer. Even a stock DC setup will crush 50A on any kind of minimal incline and shut the BMS down. Had to deal with a couple of these. You need like 3 at min in parallel for a golf cart. Even stock ones.
I have 4x of them now. I saw a great deal and jumped straight in. The new version reviewed somewhere on YT has data port added, no doubt price increase. KISS, Keep It Simple Stupid. I will add flashing lights, bells and whistles later on.

@@tobisreallifeskillswithtobi 🇨🇦 To busy to test another golf cart battery. I have three waiting for warm weather and firm ground. 😀
@@Roll2Videos Haha, I bet ;-) I'm looking forward to those tests!

How about inbuilt BMS battery balancer? Someone said its 30mah only and proper one must be installed in it.

@@ProMace That sounds exciting! Let us know how it works :-)
I just received the same battery! So far impressed, but confused on the float voltage?
53.84v as per the 100% state?
Thanks for the video! Where do the qr codes lead from the cells? Can you share the link?
I just put the information what I found online: th-cam.com/users/shortsmK1Fp5fdD5Q
I hope this helps.
I used the serial numbers got the same production date. Got hithium cells @@tobisreallifeskillswithtobi
They are the same company as Eco Worthy. This is Eco Worthy step brother but they are essentially identical.

Would you say this is a safe battery? What kind of charger would you use?
Tobie do you like DC House 48v better then the xrh 48v?

How long can you run a golf cart on a single charge
With that 50A cut off you can't even drive a cart up a ramp to a trailer. Even a stock DC setup will crush 50A on any kind of minimal incline and shut the BMS down. Had to deal with a couple of these. You need like 3 at min in parallel for a golf cart. Even stock ones.
Thanks for your feedback and watching!
I'd love to throw one of these on my ebike on a trailer. awesome!
