My duct tape battery had 100's of spot welds joints, some bad joints amongst them. Claimed as 20Ah it only ever gave 12Ah (despite stripping the thing and repairing the bad connections). I'd never get one again.
The cells that make up my current battery are 40152's- 40mm diameter by 152mm long. They are threaded (easily connected with busbars) so the overall length is 165mm, and weigh 480g each. They are 15Ah, maximum continuous discharge 10C (150 Amps), maximum discharge 15C (225 Amps), maximum charge 3C (45 Amps). In the pack the discharges are limited by the BMS to continuous 50A / maximum 100A, but further limited to 50 Amp maximum by my programmable controller.
Charger is 8 Amps so it's only a couple of hours to charge from hitting the LVC.
I don't think I'll be overworking them.
