Product Name: 2 string 8.4V 20A lithium battery protection board (standard version)
Product model: HW-392
Charging voltage: DC 8.4~9V
Continuous discharge current: up to 20A (if the heat dissipation environment is not good, please reduce the load current)
Continuous charging current: up to 10A
Product size: 45*15*3.5mm
Applicable choice: Suitable for lithium battery with nominal voltage of 3.7V and full charge of 4.2V
(including 18650, 26650, polymer lithium battery), with starting current 25A, power less than 50W electric drill, or 168W resistive load
Note 1: Successfully starting the drill requires 2 10C-20C power batteries, or 4 5C-10C
Power battery (recommended power battery model: SONY VTC4, VTcC4A, VITC5A, VTC6)
For 0V and 84V cables, use copper wire of 2 square millimeters or more (nickel sheets cannot be used!!!).
Note 2: When welding the battery for the first time, it needs to be charged before outputting; strictly according to the diagram wiring 0V, 4.2V, 8.4V, do not touch any components on the board when soldering the wire, do not intentionally short circuit.
