DIY 14S5P ebike battery update: custom polypropylene shell
Quick update on my battery build from my previous post.
I made custom outer sleeve from 1 mm polypropylene sheet, shape around the pack profile. Its amazing that even cheap packing tape grips the PP pretty well. I'll reinforce it with fiberglass tape when I get it.
My next steps:
Fishpaper over the exposed nickel
EPDM around the perimeter and BMS installation
Mount it all inside a frame triangle bag with EVA foam for cushioning
Still work in progress. The current shell is mainly for mechanical protection.
Curious of what you guys think so far!
