This is a protection board for a single cell Lithium Ion battery cell using the extremely common combination of DW01A and 8205 dual mosfet.
It suits lower current applications where you will require 1-2A maximum continuous, peak up to about 3A.
This board will disconnect the battery from discharging when the discharge current exceeds roughly 3 Amps within 10 milliseconds. Similarly it will disconnect the battery from charging when the charge voltage exceeds roughly 4.3v. And it will disconnect the battery from discharging when the battery voltage drops below about 2.7v.
This is NOT a charging board, repeat, this is NOT a charging board, you need to use an appropriate CC+CV charger to batteries packs, this handles protection, a properly designed system should not trigger the protection circuit.
I'm not going to tell you how to use this, if you are buying this, you already know what you are doing, or you shouldn't be playing with fire. Never rely on just one thing to protect you, others, or your things, always have a backup plan.
You might also want to check out my protected charging board as an alternative which incorporates both protection and charging in one for a single cell.
B+/- are the battery connections, P+/- are for the load/charger.
