“Connector for single-cell 3.7V Li-Po battery (battery shall include protection circuitry against SC, OD, OC)”

What? There’s a battery charge controller on-board yet they cheap-out and do not bother to include a cell protection IC? That’s terrible!

They should have put a nine-cent BRCL3130ME protection chip [1] on the board. Then any cell can be used with it, not just cells with built-in protection. The BRCL3130ME is like the ubiquitous DW01 protection chip [2] but with the two external MOSFETs built-in.
