Your recommendation has convinced me and so I ordered the very same DIY box (really exactly the same including JK inverter BMS, flexible busbars, etc, but without the "Yixiang" name on it) from another dealer at Alibaba. It was about 70 € cheaper than that with the Yixiang brand. Probably Yixiang is not the manufacturer but only one of many dealers. When I placed my order I was told that deilivery time to Germany should be 6 to 8 weeks, but I got it already after 3 weeks from a store in Poland. And since Poland is member of the EU I hat no problems with coustoms, duty and tax. My cells (bought from a dealer in Germany) should arrive next week. Thank you for your good work ...
Could you please put a link to the seller you bought the DIY box from? I would appreciate such information very much as I am from Poland so delivery could be quick and zero custom duty and VAT tax burden.
Thank you so much for your testing ,we have a set of the exact same cells with the same manufacturing date as yours Andy , cant wait to see what your testing shows.
@7:30 that was a major design screwup on the PCB design, they should have set a keep out area around the screws to prevent it shorting the batteries out if the solder mask is penetrated, the solder mask isn't really meant as an insulation and should never be relied upon.
Hi Andy! The case quality is okay, I ordered 4 pcs, but on one case from this seller I burned out 2 BMS due to there garbage PCB s. The design is very poor. You should remove some fixings screws, they recommend some of them after others so finally remain only 3/pcb. On one BMS gone the temperature sensors indications and in the other I replaced together with new PCB s and wires once I plugged in the wires from PCB to BMS, sets 1 to 4 some spark and fumes come out and BMS cells voltage and temperature indications gone. I mention that I checked the correct voltage on the wires plugs from cell 1 to 16 and was fine. So my recommendation is avoid this cases until this issue is solved by the factory not by us doing some compromise.
Before placing the busbars, it is a good idea to use a clean stainless bristle wire brush to remove the insulating oxide coating from the top of each cell terminal, just prior to torqueing down; otherwise looks like a great case.
Nooooooooo. We've been there. Best is to use nothing. Never had any issues without creme, paste or other chemicals in between. Especially not with these round welded terminals.
Excellent box! I recently got two of them. They have a couple of quality issues tho, so be aware of: - Both my boxes had displays mounted upside-down. Fix is relatively easy, but I had to remove the 16 screws and the front panel again :( - The connector on one of the displays had broken off. I had to solder it back on. No big deal for me, but others may struggle a bit.
7:09 When I received my Yixiang box, that particular screw had scratched the PCB and into the copper basically shorting B9- to case. Several other screws were also in the same condition.

How do you like the casters andy..FYI their new box has holes!! Yes, finally, they put ventilation holes in the outside of the case. Also, my cells were very new. In fact, they were made just 3 months before me getting them. I had one viewer suggest a great idea. Use the sticky foam to stick to the Epoxy that way no sticky crap is on the cells and the pieces are now bonded. Perfect!
The rollers are fine, I just don't like their position under the floor. The front ones are too far away from the corners and will bend the floor sheet if 2, 3 boxes are stacked on top. The back rollers are just under the battery frame and have much mor support and rigidness in that position. I have this on my list of improvements for Yixiang.
Hi Andy, I am ordering 23 of these with Rept cells, I did put a bug in Becky's ear a couple weeks ago about getting her boss to put pressure on JK to get back to talking/listening to you about there deficiencies, I hope it has some success. I think I am done with QSO unless they make some major changes to the products and customer service.
I know Yixiang and also Gobel talked to JK. There are many JKs in China unfortunately😂 But, yeah, I have contact again to one of their engineers. I just left a community comment here on the channel.
Just bought this kit thanks. I got 320ah cells after I spoke with the seller they said they’ll fit and gave me a package deal. 1600 us with shipping for 16 kWh…. Feel like an Idiot for my other lfp purchases lol
The jumper (Madi’s) between cells 8 & 9 has only half the current capacity of the flexible buss bars. With light charge and discharge that won’t be a problem but with repeated cycles with high loads you might start to notice an imbalance. I’d either use two jumpers or extend the slot on a flexible buss bar to keep things uniform.
I was thinking the same. I would of used thicker and shorter wire to get the resistance lower. I bet using a milli-ohm meter it will show a higher resistance there at 8 - 9. On one of Ray Builds Cool Stuff video's it is demonstrated what difference it makes.
This battery will be one of many in the OGGA, so current is not a problem. Also, we have tested a few busbars with 200A and Maddi's were the best. Better than the standard ones coming with the cells.
Hi Andy. Thank you for this video. I got the same one 2 weeks ago. In mine all the screws were out of torque. The display was upside down. And there were no insulation rings included. They did send me a mail to remove screws to prevent the shorting you talked about. All small things that are easy to solve. They provide good service. and respond quickly. The second box is already on its way here. Thank you for this gem. Prost ps. Wenn Sie diese Informationen lieber nicht hier haben möchten, verstehe ich es, wenn Sie sie löschen
@@OffGridGarageAustralia Moin Andy. I received my 2nd this week. And it remains an excellent diy set. But you notice that they take shortcuts. With the first one the handles and clips were mounted on the side. And the BMS connected to the fuse. The 2nd one came with the handles and clips in a bag. In both deliveries all the screws were through the cabinet because the bag was broken. So check very carefully whether a washer has ended up somewhere between the BMS. There is also no longer a fast disconnect on the + thin cable of the BMS. And no more DRY connector with it. I was unlucky this time because the Run LED was bent during installation. I remove the PCB and straighten LED. They did solve the problem with the PCB screws with insulation disks. Still a great kit. If I had enough PV power I would buy another one. Prost und einen schönen Tag im sonnigen Australien. Grüße Sebas
@@pondandmore873 Thanks for sharing. Yeah, they change the layout and design very often. I think the next one has a new circuit breaker as well as some vent openings at the side of the box.
10:56 Hi Andy, why you only use 4Nm for the Busbar nuts? From what I have seen in the forums and everywhere else All recommend 6Nm. Is there a special requirement for these Xinxiang Box + cells? I ordered the same combination at Ali and it’s currently on the way. Now I‘m a bit unsure. I don’t want to kill a cell by using too much torque. 🤔
Nice job Addy, good design very much like the Seplos, but with all the upgrades. You need to finish that power room off, as I have read in the Guardian that your going to get very warm weather next week!
Thanks for all the review, incredible value for anyone looking to build a diy battery! But seriously, who can prefer philips head over Allen key 😅 Allen are awesome and almost never strip
@@mikebarry229 made worse by the existence of posidrive/prodrive/pozisquare and probably others trying to negotiate the patent process. I can't ever recall cam out on allen/hex, spline/star or torx unless there was a lump of crud filling the void and that's operator error not product failure.
@@OffGridGarageAustralia If you were to come in contact with one of your ac leads you could shock yourself.

We can probably come up with 100 other examples where it is just careless and grossly negligent to wear anything like rings, necklaces or even glasses.
I’m a bit confused because, in a previous video, the JK BMS system seemed to have many unresolved issues when used with more than one battery in the Victron ecosystem. I’m wondering if it’s possible to buy three of these battery packs and have them work in parallel with the Victron Multiplus II
JiKong has Ghosted everyone for over 2 weeks now. Zero interaction of ANY sort, no response or anything when queried by Vendors/Resellers, Clients/Customers & users. BIG Thread at DIYSolarForum on it and elsewhere as well.
Yes, that will work but the JK need better software. That's what I'm working on with JK atm. See the recent community post on the channel. The BMS will still work with Victron, just not report if one turne off.
@@OffGridGarageAustralia I would like Andy to test a new PCB board: 12V-24V-48V for 280Ah - 304Ah cells from Jehu, would that be possible? 24V PCB: 280Ah - 304Ah should fit inside the DIY battery boxes from the video.
Good stuff Andy , thank you for the detail. I want to build these batteries but they will have to work alongside my 15s 200a batteries , can these Yixiang batteries be configured to 15s ?
Hi Andy, very good, clear and practical! What about your previous very criticals issues with JK ? Has this now suddenly and magically evaporated? New firmware?
You have to use a Victron Type A cable and connect the BMS side to the JK CAN port. The other side of the Type A cable goes into the CAN-BMS port of the cerbo. In the JK BMS you have to select the Victron protocol (4) in the settings. In the Cerbo, go to Settings - Services BMS-Can Port and change the profile to 500kbit/s if not already set. Under network status, you can check if data packages are coming in Rx and sending Tx. See here for all details: off-grid-garage.com/my-settings/
Yes, correct. Works perfectly fine. I let them sit on 3.45V for 30min to allow balancing and have the re-bulk timer set to 10h to ensure, it will charge to 3.45V only once a day.
Hi Andy, thanks for all your information, Fanny to see that ONE off the manufactors zend me a link to one of your product so I could see a “independent” review. Well done! Regards Eloy
Quick question. This box as two positive and two negative terminal. What if I connect two EG4 6000XP in parallel together can I just connect inverter one to pone positive and negative terminal on this box and inverter two on the next positive and negative terminal on the box or do I need two busbars to to connect positive and negative from both inverter and a single cable to one postive and negative on the box ?
Andy, what is your opinion about fuses (per pack) and the type to use? There seems to be consensus that we should use a T-class fuse per pack, because these are one of the few that er rated for the shortcircuit current of lifepo cells (which is higher than the 2.5kA a megafuse can handle)…
Hey, up north. I know you from your posts on the forums. I have this box and I'm trying to decide if installing in either the vertical position or tipping it on side, handles facing up and down would put undue stress on the cells? I have very limited space. I contacted Yixiyang and they said vertical is no problem, but I have read otherwise online. I trust your experience so I figured I'd ask.
@@rtsrts2317 In my personal opinion, cells should be placed upright, not on their sides. I know technically it's fine, but in a DIY situation, I always put them upright. No need to put them under stress by the weight of other cells on them...
Andy, thanks for keeping us up to date with these builds. Do you think you could review this 48V prebuilt kit, Lithiumway Batteries from Rockhampton. Says they are A grade cells up to 330Ahr from EVE with paperwork provided. Old JkBMS or inverter JkBMS are options.Says made in Australia! Fairly competitive price if they are A grade.
@@OffGridGarageAustralia- know exactly where you are coming from, that's what I thought when the DCS vs SF case blew up - no YT reviewer is going to be sued by Chinese manufacturers -their legal system can't cross borders. Of note I have a 15kWh DCS LiFeP04 51.2V storage battery off-grid that I replaced a 17yr old Pb Acid battery 4 yrs ago. The DCS battery is now doing well after I added a JK standalone active balancer. Thanks for your great videos which are full of detail, allowing users to understand their batteries and this holds manufacturers accountable.
I ordered this box along with REPT 320 ah cells from Yixiang. I tested 8 out of the 48 cells and they all pulled 329-333 AH individually. After building the box, I top balanced the pack for 2 days to where all cells were within 2mV with an average voltage of 3.64V! Together, the pack only pulled 323 AH at 40 amps! Could this be from over compressing? I followed your steps and tightened the bolts to where the plates were flush with the case, I thought they seemed a little tight but this is my first time building a pack. I plan on capacity testing those cells as individuals soon to see. What happens if they are over compressed?
I've just taken delivery of one of these and about to start building it, so I can tell you it's around 26kg before adding cells. I don't think it's designed to use as a 24v bank, it comes with a 48v BMS.
Eine Sicherung ist auch immer ein Widerstand und verbraucht Energie. Damit erzeugt man an dieser Stelle im Batteriepack eine Differenz zwischen den Zellen.
That’s potentially damaging to the bms or its balance circuit. Traditional it’s at the positive output but it can also be at the bms’s negative output.
Great I ordered three of these. The manufacturer cannot answer my question and there is nothing in any of specs published. What is the maximums size of the battery cavity before compression? I'm guessing around 600-700mm but I need to be more specific. Thanks you for anyone who can help.
I have a question about fuse (switch): this is mounted on negative terminal. Battery bank is connected to Cerbo with VE.can to CAN-bus cable. There is Ground, Can H and Can L. If we turn off the fuse, will the current damage the CAN socket in the BMS? Positive terminal battery (+48V) is still permanently connected . Now I have a battery ready to connect and I'm thinking about it. Have you turned off your batteries while working (Yixiang)?
@@OffGridGarageAustralia RF (fire resistant) or normal? You can consider OSB first and then plasterboard so you can attach more heavy stuff more easily afterwards to the wall
Hi Andy i want to make 200ah battery pack by connecting 2 pieces 100ah in parallel and then put all 16 pairs of cells in series to make 51.2v...is it a good idea?
Yes, you can do that. Parallel 2 cells together and then series connect 16 of these pairs. It will make a 2p16s battery. You can use one 16s BMS to control this battery. The downside is that you can't control single cells. The two in parallel act as one for the BMS. So, if one of these two cells has a problem, it's hard to detect. To overcome this problem, build two 16s batteries with their own BMS each (full cell control and monitoring) and parallel these two batteries together afterwards. It also has the advantage, that you can take one battery offline (repair, maintenance) while the other one keeps powering your system in that time.
Hello Andy, i have a simular issue with not matched cells i got from QSO. They never got together, they still have different charge curves after 150 full cycles. Would be verry nice to know, how your cells behave over the time.
I'm wondering why they offer 48v and 51.2 versions with a different price - any idea if there is a difference except the price. BMS is on both JK 200 amps.
Hi guys, I have an off topic question. I have 2 24v mppt charge controllers, can I use them to charge 2 24v batteries that are being hook up in series as 48v system. Is there any problem with is arrangement ? Thanks.
Hi Andy Had some damaged EVE MB30 cells on a delivery from EEL , would a charge / discharge capacity test and internal resistance test be enough to confirm it is cosmetic damage only ???
It depends on the damage. I the corner is dented, it could short some of the internal layers if not now, it could over time. If it is just scratches, it should be OK.
This is exactly what I've been looking for - I need 4 of them. Price seems good, but shipping to Oz is nearly as much as the box - 307 USD. Based on the suggested delivery date that's clearly air freight, but they don't seem to offer sea freight. Especially irritating given that delivery to the US is less than half that. Any suggestions for ways around this?
Put all in your shopping trolley on Alibaba and get in contact with them. Ask for Miao and that I have sent you. They should give you a new quote incl shipping.
@@OffGridGarageAustralia Delta @ 3.500V is very small less than 5mv (maybe because of JK's active balancing). After a week of cycling, delta is now getting better less than 20mv. So I think it is all about more cycling.
Hi Andy, wonderfull video from you. Again! 🙂. Would you connect this case to HA. Then it would be great that you can check the 2 special cells with historical data. I think, that would be great to make the analizing after the first charging process.
Hey Andy, Something has me puzzled. What type and thickness foam is put in between? Expected properties : 1) It is supposed to dampen the pressure, so it probably has some air bubbles and elastic properties. 2) It is supposed to transfer heat between the cells, but then you don’t want the air bubbles/insulation 3) It is supposed to isolate electric current and not react to the petc film around the cells Please share your findings?
@@OffGridGarageAustralia thanks for sharing your thoughts. Does it by any chance also state what material the foam is made of and how thick it is? I don't have the box, but construct things myself. I would like to understand what it is and build using this foamy material. Mostly for camper solutions, so because it is mobile and sometimes on rocky roads, it would benefit quite a bit from this foam (at least I expect it would).
@@Arjen46 EVA is made from synthetic polymer of ethylene and vinyl acetates. (I googled that, didn't know myself either). Thickness can vary from 0.1mm to 4 or 5mm and even thicker.
I was going to purchase one of these, but for some reason the shipping is higher during checkout. Shipping is over 50% of the cost of the box. Did I do something wrong?
Thanks for the video! For my current batteries I built the enclosure myself, but I'm definitely going for a prebuilt box like this one when I expand on the current situation! Am I correct that the V15 hardware is receiving more firmware upgrades, but V14 hardware is stuck on V14.20? I can't seem to find a v14.20 at least and I now see that V15 goes all the way to v15.27... Does anybody have more info on this?
What fun is that? I love building my own batteries and each time I build one I learn something and the next one is better. This is sissies. Hey Andy, what is the purpose of the epoxy sheet between cells? I know we all do it but I am not sure the reason or even if it is necessary?
battery garage must be the new channel title considering the amount of batteries ? The sticky tape is also an improvemnt to point on cause I missed that when I built the EVE V4 battery.
Hi Andy, While this is seemingly a great battery box, I thought you were advising MOVING ON from batteries that use the JK-BMS as detailed in your video of a couple of weeks ago? I'm trying to determine if the savings from this DIY box will be worth the myriad of potential communications, instability and compatibility problems between the JK-BMS and whatever inverter I select, compounded by the poor customer service and poor communication so many people have experienced. Thanks for your thoughts...
The title said 'moving on?' That was a question to the community. Have a look at the community post I recently made on the channel. There is progress (and hope?) with JK.

Hello Andy, greathings from Ron from the Netherlands, Gday mate, great video, i just build my first Yixiang 48V DIY Battery Kit with 280Ah EVE cells, I found something strange..... Maybe this is interesting for everyone.!! While installing the battery I noticed something, All batteries were between 0.19mΩ and 0.20mΩ before I placed them in the DIY box and compressed them. But after I placed both PCB boards and before I wanted to connect the measuring wires, I wanted to check the IR again. Very strange, it surprised me a bit. the internal resistance was suddenly 0.30 mΩ on all 16 individual cells. Can you or someone else check that also on your battery? I thought I had placed too much compression on the cells, but that was not the case... as soon as I disassembled the PCB - A and PCB - B, and i measure again, the cells were 0.20mΩ again. Conclusion: probably inductive voltage?? metal over the batteries?
PLEASE HELP... I'm nearly finished putting together my battery box with 304a/h EVE cells in this XIYANG Box but 1 out of the 4 NTC Connections is missing, (NTC2)...
Can I just solder a piece of figure 8 on to each side of the NTC2 terminals...?? And I've tested for continuity between the terminals on the other NTC terminals to the lug on the end of the figure 8 and I don't seem to find continuity, PLEASE HELP 😬
Can I use the batteries without it...?? Any help from anyone would be GREATLY APPRECIATED... I've taken the heat shrink off another one and it appears to be a thermal sensor as the terminal on the end doesn't make contact with the figure 8... Also I only have POSITIVE cables coming from the central rail, except B1-, then B1+, B2+, NTC1, B3+ B4+, B5+, B6+ B7+, B8+ B9-, B9+ B10+ NTC3, B11+ B12+, B13+, B14+ NTC4, B15+ B16+

Hi Andy. Thank you for this video. I got the same one 2 weeks ago. In mine all the screws were out of torque. The display was upside down. And there were no insulation rings included. They did send me a mail to remove screws to prevent the shorting you talked about. All small things that are easy to solve. They provide good service. and respond quickly. The second box is already on its way here. Thank you for this gem. Prost ps. Wenn Sie diese Informationen lieber nicht hier haben möchten, verstehe ich es, wenn Sie sie löschen
Thanks for sharing. I will get back to them and let them know to better check what they are sending. That is not great.
I'm not deleting comments.
@@OffGridGarageAustralia Moin Andy. I received my 2nd this week. And it remains an excellent diy set. But you notice that they take shortcuts. With the first one the handles and clips were mounted on the side. And the BMS connected to the fuse. The 2nd one came with the handles and clips in a bag. In both deliveries all the screws were through the cabinet because the bag was broken. So check very carefully whether a washer has ended up somewhere between the BMS. There is also no longer a fast disconnect on the + thin cable of the BMS. And no more DRY connector with it. I was unlucky this time because the Run LED was bent during installation. I remove the PCB and straighten LED. They did solve the problem with the PCB screws with insulation disks. Still a great kit. If I had enough PV power I would buy another one. Prost und einen schönen Tag im sonnigen Australien. Grüße Sebas
@@pondandmore873 Thanks for sharing. Yeah, they change the layout and design very often. I think the next one has a new circuit breaker as well as some vent openings at the side of the box.
10:56 Hi Andy, why you only use 4Nm for the Busbar nuts? From what I have seen in the forums and everywhere else All recommend 6Nm. Is there a special requirement for these Xinxiang Box + cells? I ordered the same combination at Ali and it’s currently on the way. Now I‘m a bit unsure. I don’t want to kill a cell by using too much torque. 🤔

Always good to lose the wedding ring when working around electrical connections Andy. lol
Lose not loose
Auto correct takes control
What's wrong with the ring? Explain what could happen and how?
@@OffGridGarageAustralia If you were to come in contact with one of your ac leads you could shock yourself. My father's wedding ring fit very loosely later in his wife and would occasionally fall off. so Imagine if your wedding ring fell off causing a dead short across your input or generator leads? If you have a lathe and you snagged the ring then it could drag you finger and or hand into the lathe.
@@innerspaceavailable We do NOT work on live AC wires ever! So this can never happen.
If you ring can fall off, well, obviously you are aware of that then and take measures to avoid any accidents in such regard.
Operating machinery with jewellery is beyond my understanding. Just follow the safety regulations in place. Ignoring them can be fatal.
We can probably come up with 100 other examples where it is just careless and grossly negligent to wear anything like rings, necklaces or even glasses.
Hi Andy, why is there no fuse or breaker between the cells and the BMS?
A BMS can also cause a short circuit...
Hey Andy, there is a V2 of this box coming out very soon. Do you think you will get one to test it?
I’m a bit confused because, in a previous video, the JK BMS system seemed to have many unresolved issues when used with more than one battery in the Victron ecosystem. I’m wondering if it’s possible to buy three of these battery packs and have them work in parallel with the Victron Multiplus II
JiKong has Ghosted everyone for over 2 weeks now. Zero interaction of ANY sort, no response or anything when queried by Vendors/Resellers, Clients/Customers & users. BIG Thread at DIYSolarForum on it and elsewhere as well.
Yes, that will work but the JK need better software. That's what I'm working on with JK atm. See the recent community post on the channel.
The BMS will still work with Victron, just not report if one turne off.
that was very easy to assemble
Thanks a lot for dropping a comment. I'm watching your channel for years! Big fan with everything you're doing.
@@OffGridGarageAustralia I would like Andy to test a new PCB board: 12V-24V-48V for 280Ah - 304Ah cells from Jehu, would that be possible?
24V PCB: 280Ah - 304Ah should fit inside the DIY battery boxes from the video.
Good stuff Andy , thank you for the detail. I want to build these batteries but they will have to work alongside my 15s 200a batteries , can these Yixiang batteries be configured to 15s ?

Thank you and welcome!
Thanks Andy!
Merci Andy ! 🥰👍
De rien mon ami!
Hi Andy, very good, clear and practical! What about your previous very criticals issues with JK ? Has this now suddenly and magically evaporated? New firmware?
I just published a community post on the channel's page here on TH-cam.
JK has a new FW by this week, fixing some/most of the issues. We will see...
Hi sir
Thank you for the knowledge you share now I have my own build battery...
From Philippines
Where did you get the wheels from and how did you install them?thanks great video
The wheels came with the box. There was an M8 thread welded into the case, so they just screwed in.
Thanks Andy
Thank you, Wayne!
Hi! Cool DIY box but still confused about the possibility to connect JK with a Cerbo GX. How? .)
You have to use a Victron Type A cable and connect the BMS side to the JK CAN port. The other side of the Type A cable goes into the CAN-BMS port of the cerbo.
In the JK BMS you have to select the Victron protocol (4) in the settings.
In the Cerbo, go to Settings - Services BMS-Can Port and change the profile to 500kbit/s if not already set. Under network status, you can check if data packages are coming in Rx and sending Tx.
See here for all details: off-grid-garage.com/my-settings/
Does the sticky foam come normaltwith the cells or Box?
With the eve MB31 i dit not receive sticky foam.
They come with the box. The cells sometimes come with the yellow epoxy sheets.
What are your latest parameters for bulk and float ?
Are they still 3.45 bulk per cell
And 3.35 float ?
Yes, correct. Works perfectly fine.
I let them sit on 3.45V for 30min to allow balancing and have the re-bulk timer set to 10h to ensure, it will charge to 3.45V only once a day.
Hi Andy, thanks for all your information, Fanny to see that ONE off the manufactors zend me a link to one of your product so I could see a “independent” review. Well done! Regards Eloy
Quick question. This box as two positive and two negative terminal. What if I connect two EG4 6000XP in parallel together can I just connect inverter one to pone positive and negative terminal on this box and inverter two on the next positive and negative terminal on the box or do I need two busbars to to connect positive and negative from both inverter and a single cable to one postive and negative on the box ?
Andy, what is your opinion about fuses (per pack) and the type to use? There seems to be consensus that we should use a T-class fuse per pack, because these are one of the few that er rated for the shortcircuit current of lifepo cells (which is higher than the 2.5kA a megafuse can handle)…
That's a big topic.
I would recommend using NOARK DC breakers for that purpose. 25kA breaking capacity and double pole, so they isolate.
Have you come to a conclusion on the c quality of this unit after a month of use???
You put a spotlight on me - don't shoot the messenger if it doesn't work out in this case :)
Hey, up north.
I know you from your posts on the forums. I have this box and I'm trying to decide if installing in either the vertical position or tipping it on side, handles facing up and down would put undue stress on the cells? I have very limited space. I contacted Yixiyang and they said vertical is no problem, but I have read otherwise online. I trust your experience so I figured I'd ask.
@@rtsrts2317 In my personal opinion, cells should be placed upright, not on their sides. I know technically it's fine, but in a DIY situation, I always put them upright. No need to put them under stress by the weight of other cells on them...
@@upnorthandpersonal So, it's okay if the build was professionally designed to be vertical, but for the diy schmuck, like me, not advised.
@@rtsrts2317 Just that it's not worth the risk. In a 'professional' pack, it's not your responsibility should things go wrong.
You said it, so you are in charge.☺️
We will see, ey?
Hi do you ever sell any of yr batteries that you have?
Andy, thanks for keeping us up to date with these builds. Do you think you could review this 48V prebuilt kit, Lithiumway Batteries from Rockhampton. Says they are A grade cells up to 330Ahr from EVE with paperwork provided. Old JkBMS or inverter JkBMS are options.Says made in Australia! Fairly competitive price if they are A grade.
I'm not revieing batteries made in Australia for legal purposes, sorry.
@@OffGridGarageAustralia- know exactly where you are coming from, that's what I thought when the DCS vs SF case blew up - no YT reviewer is going to be sued by Chinese manufacturers -their legal system can't cross borders. Of note I have a 15kWh DCS LiFeP04 51.2V storage battery off-grid that I replaced a 17yr old Pb Acid battery 4 yrs ago. The DCS battery is now doing well after I added a JK standalone active balancer. Thanks for your great videos which are full of detail, allowing users to understand their batteries and this holds manufacturers accountable.

Hi Andy, I stumbled across this video. Can i please get some info on the white battery stack that's in the background?🙏
I ordered this box along with REPT 320 ah cells from Yixiang. I tested 8 out of the 48 cells and they all pulled 329-333 AH individually. After building the box, I top balanced the pack for 2 days to where all cells were within 2mV with an average voltage of 3.64V! Together, the pack only pulled 323 AH at 40 amps! Could this be from over compressing? I followed your steps and tightened the bolts to where the plates were flush with the case, I thought they seemed a little tight but this is my first time building a pack. I plan on capacity testing those cells as individuals soon to see. What happens if they are over compressed?
a how much force should the cells be tight please
Ive seen the voltage curve do this before i corrected by turning on balance at 3.45 and same as charge voltage 55.2
What is the weight of this box?
Can it be configured as a 24v bank?
I've just taken delivery of one of these and about to start building it, so I can tell you it's around 26kg before adding cells.
I don't think it's designed to use as a 24v bank, it comes with a 48v BMS.
I always put a fuse between cell 8 and 9 instead of a bus bar.
Nice kit.👍
Eine Sicherung ist auch immer ein Widerstand und verbraucht Energie. Damit erzeugt man an dieser Stelle im Batteriepack eine Differenz zwischen den Zellen.
Why?
That’s potentially damaging to the bms or its balance circuit. Traditional it’s at the positive output but it can also be at the bms’s negative output.
Yeah, not great I think as it can damage the BMS as Karl said.
Great I ordered three of these. The manufacturer cannot answer my question and there is nothing in any of specs published. What is the maximums size of the battery cavity before compression? I'm guessing around 600-700mm but I need to be more specific. Thanks you for anyone who can help.
I have a question about fuse (switch): this is mounted on negative terminal. Battery bank is connected to Cerbo with VE.can to CAN-bus cable. There is Ground, Can H and Can L. If we turn off the fuse, will the current damage the CAN socket in the BMS? Positive terminal battery (+48V) is still permanently connected . Now I have a battery ready to connect and I'm thinking about it. Have you turned off your batteries while working (Yixiang)?
Heya, nice DIY bild looks very good
Yeah, it's really good!
What kind of wall material will you attach to the frame for the battery room?
Plasterboard both sides with insulation in between.
@@OffGridGarageAustralia RF (fire resistant) or normal? You can consider OSB first and then plasterboard so you can attach more heavy stuff more easily afterwards to the wall
Hi Andy
i want to make 200ah battery pack by connecting 2 pieces 100ah in parallel and then put all 16 pairs of cells in series to make 51.2v...is it a good idea?
Yes, you can do that. Parallel 2 cells together and then series connect 16 of these pairs. It will make a 2p16s battery. You can use one 16s BMS to control this battery. The downside is that you can't control single cells. The two in parallel act as one for the BMS. So, if one of these two cells has a problem, it's hard to detect.
To overcome this problem, build two 16s batteries with their own BMS each (full cell control and monitoring) and parallel these two batteries together afterwards.
It also has the advantage, that you can take one battery offline (repair, maintenance) while the other one keeps powering your system in that time.
Hello Andy, do we have any promotion code for the Yixiang box? Thank you!
Hello Andy,
i have a simular issue with not matched cells i got from QSO.
They never got together, they still have different charge curves after 150 full cycles.
Would be verry nice to know, how your cells behave over the time.
I guess we will find out. HA will take care of that...
I'm wondering why they offer 48v and 51.2 versions with a different price - any idea if there is a difference except the price. BMS is on both JK 200 amps.
Hi guys, I have an off topic question. I have 2 24v mppt charge controllers, can I use them to charge 2 24v batteries that are being hook up in series as 48v system. Is there any problem with is arrangement ? Thanks.
That's not going to work, you need 48v charge controllers
Hi Andy
Had some damaged EVE MB30 cells on a delivery from EEL , would a charge / discharge capacity test and internal resistance test be enough to confirm it is cosmetic damage only ???
so you did not talk to EEL? I bought only the box there with only minor scratches. the cells i bought in europe...
It depends on the damage. I the corner is dented, it could short some of the internal layers if not now, it could over time. If it is just scratches, it should be OK.
This is exactly what I've been looking for - I need 4 of them. Price seems good, but shipping to Oz is nearly as much as the box - 307 USD. Based on the suggested delivery date that's clearly air freight, but they don't seem to offer sea freight. Especially irritating given that delivery to the US is less than half that. Any suggestions for ways around this?
Put all in your shopping trolley on Alibaba and get in contact with them. Ask for Miao and that I have sent you. They should give you a new quote incl shipping.
21:00 Yixiang sent me CATL cells.
I charge the cells upto 3.500V and during discharge, the delta is >50mv.
My EVE boxes had delta of
What is the delta at 3.5V?
During charging, the delta is usually very small and only rises above 3.4V cell voltage.
@@OffGridGarageAustralia Delta @ 3.500V is very small less than 5mv (maybe because of JK's active balancing).
After a week of cycling, delta is now getting better less than 20mv. So I think it is all about more cycling.
@@DanBurgaud How long do you keep the cells at 3.5V and when do you start balancing?

Hi Andy, wonderfull video from you. Again! 🙂. Would you connect this case to HA. Then it would be great that you can check the 2 special cells with historical data. I think, that would be great to make the analizing after the first charging process.
That's what I did. Video is coming next...
Hey Andy,
Something has me puzzled.
What type and thickness foam is put in between?
Expected properties :
1) It is supposed to dampen the pressure, so it probably has some air bubbles and elastic properties.
2) It is supposed to transfer heat between the cells, but then you don’t want the air bubbles/insulation
3) It is supposed to isolate electric current and not react to the petc film around the cells
Please share your findings?
1) is almost correct.
It is more to smooth out uneven parts of the cells when they expand and contract.
@@OffGridGarageAustralia thanks for sharing your thoughts. Does it by any chance also state what material the foam is made of and how thick it is? I don't have the box, but construct things myself. I would like to understand what it is and build using this foamy material. Mostly for camper solutions, so because it is mobile and sometimes on rocky roads, it would benefit quite a bit from this foam (at least I expect it would).
@@Arjen46 EVA is made from synthetic polymer of ethylene and vinyl acetates.
(I googled that, didn't know myself either).
Thickness can vary from 0.1mm to 4 or 5mm and even thicker.

What fun is that? I love building my own batteries and each time I build one I learn something and the next one is better.
This is sissies.
Hey Andy, what is the purpose of the epoxy sheet between cells? I know we all do it but I am not sure the reason or even if it is necessary?
Safety
battery garage must be the new channel title considering the amount of batteries ?
The sticky tape is also an improvemnt to point on cause I missed that when I built the EVE V4 battery.
Some batteries come without foam, but I actually like it as it smoothes out the cell surface when they expand and contract.
Hi Andy, While this is seemingly a great battery box, I thought you were advising MOVING ON from batteries that use the JK-BMS as detailed in your video of a couple of weeks ago?
I'm trying to determine if the savings from this DIY box will be worth the myriad of potential communications, instability and compatibility problems between the JK-BMS and whatever inverter I select, compounded by the poor customer service and poor communication so many people have experienced.
Thanks for your thoughts...
The title said 'moving on?' That was a question to the community.
Have a look at the community post I recently made on the channel. There is progress (and hope?) with JK.

Hello Andy, greathings from Ron from the Netherlands, Gday mate, great video, i just build my first Yixiang 48V DIY Battery Kit with 280Ah EVE cells, I found something strange..... Maybe this is interesting for everyone.!! While installing the battery I noticed something, All batteries were between 0.19mΩ and 0.20mΩ before I placed them in the DIY box and compressed them. But after I placed both PCB boards and before I wanted to connect the measuring wires, I wanted to check the IR again. Very strange, it surprised me a bit. the internal resistance was suddenly 0.30 mΩ on all 16 individual cells. Can you or someone else check that also on your battery? I thought I had placed too much compression on the cells, but that was not the case... as soon as I disassembled the PCB - A and PCB - B, and i measure again, the cells were 0.20mΩ again. Conclusion: probably inductive voltage?? metal over the batteries?
