The original author's project used a 2 in parallel and 6 in series 21700 battery to make the energy storage module. I only have a bunch of 18650, so I made a battery compartment that can fit 3 in parallel and 6 in series 18650 with a bracket. The model is quite simple and only meets the usable standard. It uses 6 M3 cup-head hex socket screws to connect, and the screw length can be within 14mm.

It should be noted that when making the circuit part, you need to change the external resistance of the IP2368 according to the actual situation based on the circuit diagram provided by the original author to match the corresponding battery capacity and number of series.
