18650 powerbank / fieldbattery case using spring contact terminals.
With this solution, you don't have to solder your li-ion cells and risk damaging them.
If later some cells go bad you can replace them, which is difficult when soldered or even spot welded together.
It is a bit difficult to get all cells making contact with the flat terminals. I would suggest using spring terminals for both the negative and positive sides.
This case is designed for 6s8p configuration.
Parts needed:10 x hex socket cap screw M5x75mm or 80mm
10 x M5 nuts/locknuts
