This is a configurable battery pack currently set for 18650 LiIon cells (3p6s).
Printed with ABS at 0.3mm layer height.
A test print with for example scaled z-axis is recommended to verify the tolerances of battery cells and printer.
Some parts, such as the battery compartment cover, are not completeley parameterized and have to be adapted to a different number of cells.
Parts:
Battery pack spec. for long cycle life with Samsung INR18650-35E:
I am charging/discharging this battery with a charger like the "ISDT Smart Charger Q6", so I did not plan to install a BMS board.
I purposely made the box a little smaller, so that the lid can be pressed firmly into the box by 3 cable ties or, as shown in one of the pictures, a strap.
