I don't see any kind of grounding screw/terminal??? And there is no support directly under the end of the PCB when you hook up the BMS plugs. The PCB bends way to easily and can crack the electrical traces.
Thanks for your suggesions,our engineer said that only the battery above 110V will need grounding.and we will put an EVA tapes under the PCB board to avoid issues.
Hello,www.alibaba.com/product-detail/EEL-5kwh-10kw-JK-battery-box_1601177776290.html?spm=a2747.product_manager.0.0.612971d2aZGosL You can find my chat box through this link, don't find the wrong person~ I am Miya~ I will draft the order for you
I got mine after 2.5 months. The construction went well. The screws of the compression plate were too short so I bought longer ones. Unfortunately two Eva foams were missing. My cells are EVE 304Ah. Up to now I'm satisfied
The success will depend on what BMS is used, what balancer is integrated and how the connectivity with the external environment will be done. Cons: If one or more cells are not performing like expected, the replacement is not easy!
CCS battery pack is compatible with various BMS and can use 4A balancer. The battery has been tested many times and will not have poor performance. We have quality assurance. Please believe our investment, it is huge!😊
Actually, this version (which many manufacturers are using now) is having issues. No Grounding screw/terminal which is a major oversight. And the PCB's that bring all the BMS leads into one plug per side have no support under them where you plug in the leads from the BMS. They are bending considerably when people plug in the BMS and cracking the electrical traces. Poor design.

EVE has not allowed the flat mounting position which means EU inurances will not pay in case of a fire and what not if you abuse EVE cells this way. You are not allowed to at least here in central Europe / EU.
2:24 - I suggest to have a close look on the big red and black wire which connect to the battery terminals . The ring lug that gets connected to the terminal has to be in the right position which means the ring itself needs to be on the bottom. Otherwise the crimped ring lug would later press against the top of the cell and pressure from the terminals screw would be pushed into the top of the cell. 2:07 - shows the black cable ring lug in the wrong position cause it has to be in the opposite position. Now the flat metal part of the ring lug is closer to the table where it should be close to the ceiling. 3:03 - shows the red cable with ring lug but now in the right position, while the black on the left half is still wrong mounted cause the terminal screw will put force on the ring lug and that will lead the pressure into the top of the cell which is not really good. Not great and I have not seen any EEL video or manual which emphasizes on this topic how the ring lugs should be positioned if you screw them into the circuit breaker If you had done it wrong like I had done then you would have to unplug the front plate and disassemble the whole circuitbreaker and box assembly to get to the point where you can unscrew these 2 cable to turn them around AND i also had issues cause the red cable to the red terminal from that MCB was like in this example TOO LONG and put pressure on the circuit breaker which then was hard to get into the hole. Big mess if things go wrong and it needs a better manual and better videos - same for the whole mess regarding temperature sensors and where they have to be placed and bolted too. Finally: my pcb A and PCB b arrived only partly assembled which I learned the hard way cause at the end I had screws over where I found out that my PCBA and PCB BMS connection boards were only fixed with just 2 scews each. Bad move to not mention these topice in the videos and also not in the manual . These topics are important.
Buongiorno ho montato la batteria ma mi da errore, devo collegarmi con il cellulare e sbloccare il bms in carica e scarica? Quale app devo scaricare? E la devo comunque accendere ma mi da la luce rossa fissa
My case has just been delivered after about three months. The local distribution partner (DPD) didn't provide any track/trace information so I was really surprised to find it on my doorstep today. Anyway, it's finally there and I can proceed with the installation of my EVE 304Ah batteries
Obecnie piętrowy zestaw JK znajduje się w magazynie europejskim, ale wersja pionowa jeszcze nie dotarła. Proszę o kontakt e-mailowy, a omówimy szczegółowo: miya@eelbattery.com
The compression plate is not compressing the cells. 8-/ Look at the HUGE gap between the cells and the compression plate. The EVA tape is not even squashed. The screw underneath the circuitbreaker is not ligned up. You should do better EEL BATTERY
@@rubelbiswas939 Sorry, India cannot ship batteries at the moment, only kits, and the shipping cost is very expensive, almost catching up with the kit price~
EXW price is 269 USD!Yes, it can be transported to the Philippines. The price is very good and the logistics is fast. You can contact me with my email and we will have a detailed chat, miya@eelbattery.com
My review: Delivered after 4 months. No Manual at all, even no hint to this video in the box. There are only 4AWG or 2 times 7AWG cables. This is way to small for 200A. The cables are getting hot! You have to twist some cables, because some ringlocks or ferrules are mounted by 90° or 180° to the wrong direction. BMS B+ had no ringlock. Some screws were missing. Screws for compression plate are to short. No chance to get them in. Balancer PCB have no mounting support near the connector. This can cause a short while pushing in the connector, because PCB bends down and touches the metal bracket. The cables of the temp sensors are to short to thermal glue them on the alloy of the cells. (Mounting them on the cellbridges makes no sence.) The balancer cables are glued to the PCB pointing sidewards witch causes them to touch the sharp edge of the mounting rail. Comes with flexible 40mm2 cellbridges with thread inlets for the balancer cables. Quality of metal work looks good. Parts are fitting perfect together. Easy to assemble.
Thanks for your feedback. Our JK Box is a new model and does not have a manual yet, we put the instruction video first, and we will have it updated on our website very soon. -About 4AWG,we have tested them for sure it can easily pass 300A,and each 7AWG cable can easily pass 200A. -Screws for compression plate are too short Please make sure you are using the right one. -About the PCB board design, we will find a better way to avoid short and more safety to use. -The cables of the temp sensors are too short to thermal glue them on the alloy of the cells: We still recommend you fasten the sensor on the busbars to collect the data more specifically. Anyway, thanks for your suggestions, and this product will be better in the future.🤝
@@eelbatteryofficial Wich size of screws do you think are the right one? There were no other screws in the box, only the ones that are too short to catch the thread. They only fit, if the foam and epoxy plates between the cells are omited. How long did you tested the cables with continues current? Wich temperature did they reach ?
@Juergen_Miessmer I have one of these boxes also and I couldn't agree more with all of your comments. The small cables are just junk to much loss at high current. I am planning to build some new cables out of dual 25 mm2 for the negative and 50 mm2 for the positive. One of my balancer PCBs came with damaged pins and a dry joint.
Hello ! I order the 12V box for my vehicle.i want to buy and this 48V with jk bms .are you satisfied this 4 months ? It cost about 650 euro for Greece .is it a good product or you can recommend me another company diy box with jk bms ? Thanks 😊😊
Yes, it is still available now. This is my Alibaba link. Please come to me and I will quote you~ www.alibaba.com/product-detail/DIY-12V-Lithium-ion-Battery-box_1600696291356.html?spm=a2747.product_manager.0.0.30ff71d2z2TDGW
This battery box will arrive at the end of May~Now the European warehouse has batteries in stock. You can buy batteries first and then the battery box. I am afraid that the batteries will be sold out after the battery box arrives, so if you need it, please book with me in advance~
I had one of these delivered yesterday. Can't recommend it to be honest. The connections from BMS to Battery and BMS to terminals are insufficient and should be flexible busbars. Mine got shipped with the wrong busbars even know we discussed that my batteries have single M6 studs on them. I have contacted Howard from EEL and had no response. I am looking forward to what Andy and @OffGridGarageAustralia have to say about the box.
Can you please tell me what is the cable cross-section of Plus-cable from BMS to fuse and inverter connection (outside the box). Is it „only“ 4AWG (5,19mm / 21,15 mm2)? Or AWG 4/0 (11,68mm / 107,2 mm2)?
@@meins2881 I haven’t measured it specifically, but you can rest assured that they have been tested by technicians and reviewed by the state, and can fully support 200 amps.
@@solarcharging9743 No, how could it be possible? I will always reply to my customers! I will help my customers solve any problems, and the same goes for other colleagues. We will all help customers have a good shopping experience from purchase to completion.
When you say "on the right side" you need to say "your right side when you are looking at the front". But in this case it would have been better to say "on the Positive connector side".
When will you deliver the case by default with the New PCB with dedicated balancer Cables? Will there be an Option for the case without BMS or the New JK inverter BMS ?
Yes, there are kits without BMS, and there are also matching kits for the new JK BMS. Please feel free to click on the link to contact me if you need it~
