[Frost Autumn Awe-inspiring] Energy Storage Station Second Generation 3S 21700 Battery Box

The design is hellish! ! !

The schematic is useless (funny) and the PCB is all done by hand. . . .

So just look at the PCB directly 

Parameters: Voltage: 11.1V Current: 0-10A Maximum power: 120W

B- and P- are the interfaces for connecting the protection board. If you do not use the protection board, please short-circuit it. Otherwise, if the xt30 has no output, you can also install a fuse. 

Balance charging can be used with or without a protective plate installed (details)

Sorry for my poor welding skills. . .

Adding an xt30 to the protective board pad makes it easy to switch modes and disassemble and install the protective board.

The protective board of "Magic Reform". . B- and P- correspond to the ones on the PCB and the balance lines can also be connected in order.

With the protective board installed, it looks like it can be made into a casing.
