EEL 48V DIY Vertical Battery Kit with JK BMS(for 280Ah/302Ah):
eelbattery.mys...
contact us for more details: [e-mail]
Finally, the vertical battery box is compatible with JK 48V inverter BMS,
BMS version:JK-PB2A16S20P/JK-PB2A16S15P
The NEW box design with easier to build the battery system this time!
we put in the extra display screen and upgraded terminals this time,
hope you will like it!
Enjoy the video.

Hi EEL, it's nice to see how you assemble the boxes. I'm still waiting for my delivery which I payed three month ago! But nothing happens .. why are you so slow? Will I still get what I've payed for or how can I get back my money to buy at a vendor who is more serious?

[@Ali.ALjabery]

Hi dear, Can the cells be assembled and placed in the assembly unit to produce the battery, so that the cells are placed horizontally and not vertically??? Does placing them horizontally affect the cells and their lifespan, charging and discharging???

[@Electronzap]

Cool battery box.

[@ntram2]

I think the handles should be installed the other way around. The way they are installed now, will crush your fingers when carrying.

[@honumoorea873]

The busbar between the breaker and the Positive pole is passing ovver the nerative bussbar connected on the bms....even iff not in contact it's not good, those need to be arranged differently.

[@eelbatteryofficial]

You can look at 6:00 there, actually will not touch the protective plate, the distance is still far, thank you for your suggestion.

[@cptbill80]

nice battery. i already have one. My concern is, what is the real disadvantage of 2 terminals instead of 4 for paralleling?

[@samir101ng]

A cool new design. However, there are a couple of things to note. There is no mid plate to reduce the load on the bottom battery from the weight of the top batteries. The Seplos Mason 280L DIY BOX has implemented this change. Secondly , try making the battery connection with an option to choose an easy disconnect head instead of using lugs. Finally, it seems the space at the top is a bit tight. You can make the cover at the top to be removable for easy access. But overall, nice case and i like the screen display at the top of the box. 👍

[@ntram2]

They seem to have forgotten to add foam (or not enough foam) between every battery, so now too much space is left over at the top, so no compression is applied at all 😢 Oh well, at least is it is a DIY battery, so you can correct this error. Bit painful for a demonstration video though.

[@eelbatteryofficial]

You need to add enough foam to compress the cells, you can check 2:25, and we put extra foam for compression.

[@DukeEast]

@samir101ng I can confirm the Seplos Mason 280L Does Not have a Middle plate to take weight of the upper half of batteries..

[@ntram2]

@@DukeEast The old version does not, the new versions since end of 2023 do.

[@PhilippeCJR]

why 2 terminals and not 4, no paralleling?

[@vit_tam]

What is the brand of the torque wrench?

[@think-agile]

One question towards the architecture of the middle rail in the box: On the footage on your website there is no middle rail to additionally compress the cells in the middle of the compress plate. Here in the video there is a middle rail. Which version is the current one. Before ordering the box this would be important to know. Thanks.

[@eelbatteryofficial]

This video is the current one,thanks for your question~😁

[@PhilippeCJR]

no compression at all?

[@takeahike858]

There is no compressive device available that would meet the manufacturers specs to do it properly. You might as well let them breathe.

[@PhilippeCJR]

@@takeahike858 300kg is just 0.5Nm if you press with a plate and 6 screws lol

[@b67fstb]

Does this not harm the batterycells ?? The position of the cells is questinable ???

[@kennyrodg]

Lots of vertical kits on the market now...Batteries can be any orientation except upside down.....Apparently.

[@eelbatteryofficial]

​@@kennyrodg Basically all the wall-mounted batteries on the market are this battery position, we asked the engineers of EVE, they only suggest that the positive and negative poles face the ceiling. And with enough force to clamp down on the cells, we're launching a CCS battery module that might solve all your doubts.

[@bakhjon931]

Скажите пожалуйста сколько аккумуляторный сборки можно подключить параллельно на таком Inverter BMS ?

[@eelbatteryofficial]

the host can be connected in parallel with up to 15, and the data of another 15 devices can be monitored on the host

[@Ramjet7777]

Will this box work with MB31 cells with the single M6 stud pole as the terminal?

[@eelbatteryofficial]

Yes, you can choose the corresponding busbar when buying

Sur le groupe Entraide DEYE France (Facebook), une personne parle d'un problème sur sa batterie (vertical DIY EEL-48V 16S avec onduleur JK BMS) qui ne démarre pas. Il possède le nouveau modèle avec l'écran 4.3 pouces, y a-t-il des problèmes sur ce modèle? Où il faut mieux commander le modèle avec l'écran 3.2 pouces ?

[@AL-53]

Le dysfonctionnement du démarrage a été résolu. ( Problème carte com )

Anyone tried it?

[@pinco2004]

EVE Energy не рекомендует располагать ячейки батареи ГОРИЗОНТАЛЬНО 😮

[@typxxilps]

EVE warns german customers to use these cases for their batteries, all EVE LF and MB are not meant to be stored in these vertical boxes which will force the cells to lay flat instead of an usual upright position with the valve and terminal showing to the ceiling . No warranty regarding cycles and capacity if the EVE cells will be abused this way . Stupid move by EELL and SEPLOS anD GOBEL to sell crappy boxes and batteries that viloate the warrany terms.

[@XB-ff2gf]

While I believe you, any url source for this statement would be useful.

[@eelbatteryofficial]

This is a false statement, basically all the wall-mounted batteries on the market are this battery position, we asked the engineers of EVE, they only suggest that the positive and negative poles face the ceiling. And with enough force to clamp down on the cells, we're launching a CCS battery module that might solve all your doubts.

[@Angelorademon]

Why didn't you provide compression for batteries, 300 kg?

[@eelbatteryofficial]

This almost all battery boxes can not do, we are developing CCS battery module, it can do, please look forward to it.

[@Angelorademon]

@@eelbatteryofficial For example, I could weld stiffeners to your pressure plate and add a stiffener to adjust the height of the battery stack. Will it work?

[@eelbatteryofficial]

@@Angelorademon Your method is more difficult to achieve, the car is like us this method (using CCS and steel strip clamp), you can take a look at this video: kzbin.info/www/bejne/j6DOanaunrOqiJI

[@Angelorademon]

@@eelbatteryofficial Mr. Howard, by the way, we are already communicating via email, and I paid for the order today. I just want to say that welding the stiffeners in your box is not difficult for me, it will only take 15 minutes and it will be the most inexpensive solution :)

Can you tell me your order number? Which website is purchased, I will check the order status as soon as possible.
