I think this is an under-discussed aspect of battery building, so if this evolves into a general discussion of ideas/solutions/resources, I won't mind, but I am hoping to get some input on my specific situation.
I'm building replacement batteries for an electric scooter, the Evader EV1000. It shipped with SLAs, but by the time I got to it, it didn't have any batteries at all. However, it does have custom battery trays that I'd like to take advantage of.
My first thought is that if I could get hold of SLA shells (i.e., SLAs without the L or the A) in the right size, I could pack them with 18650s and just slide them into the trays and tie them down.
Alternatively, I could find any other box that's the right size, and make some terminal connections through the lid.
However, I'm having a tough time finding boxes that are the right size, for some reason. The trays are 8" wide by 7" deep by 5-3/4" high (170 x 195 x 140 for those of you who use sensible units), although the box could be taller since the trays are open at the top. Of course, I'd like to pack in as many cells as I can, leaving room for BMS, insulation, terminal wiring, etc. So vertical sides, squared edges, and no protrusions would be best.
Should be reasonably rugged and waterproof. Any ideas where I could find such enclosures?
Thanks for your ideas.
