Empty battery case.

[f1991]

Hello,
I ordered on DocanPower a 4s LF280k.
But I forgot to order a box to build the battery.
Can you recommend me a seller of quality box and not too expensive?
A box that can therefore contain 4 cells.
I am looking for a seller on Aliexpress, Alibaba or a reliable website.
Thanks for your advices. Peace

I got this one, originally planned for building a 4s 280Ah battery:

Eventually I ended up using it for an 8s 24v build using EVE 105Ah cells (with room to spare).
But it should fit the 280Ah cells. Make sure dimensions are adequate, just in case I missed something. Don't forget you need room for the BMS too.

Here's how my build looks like:


As for quality, it seems pretty good. I mean it's simple ABS plastic, but seems pretty sturdy. I didn't notice any bending when I pick it up.
You will need to find a solution for sealing the lid though. For now I haven't done anything since I'm still testing my pack. But you can seal it up with some silicone glue or maybe epoxy (if you aren't planning on opening it... epoxy is pretty hard).

I used the Noco 24-31 battery box for both my first build on my brothers trailer as well as the 280k's for my solar dolly. The cells fit both times and it's pretty cheap.

This is awesome ! Is there a chance to find this kind of box on Aliexpress to have a better price?

It's really not bad! But there is no Walmart in my country. I'll still see if there is an equivalent here.
How did you do your two terminals (+) (-)?

The terminals are a bolt in off-the-shelf set I picked up at my local battery store. Drill a hole, bolt through the inside, done.
