Homemade DIY battery packs

[agniusm]

So i thought we need a dedicated topic on homemade battery packs. There is one named like that but the info is one mans (DrkAngel) playground, give or take.
So folks, post your battery builds with specs, keep it simple, no charge/discharge charts needed.

This is for my recumbent trike.
They used to be HK 6s lipo packs that I dissemble and joined them into 4p.

I have another box made up of 5s.

Waiting on xt90 mounting brackets to come in this week.

Just posting some pics of a homemade 48V 20Ah ebike battery pack. It is a 10P 13S pack with a BMS. I'll heat shrink it eventually. I figured this might be useful to someone that's thinking about building a homemade pack.

All the cell to cell connections were made with 0.15mm x 7mm Pure Nickel. The 5 lead wires (18 awg) are all the same length and merge into one (12 awg wire). Lead wires were soldered to the nickel strip before the nickel strip was spot welded to the cans.

Feel free to comment about anything regarding this build.
