Product Name: 3 string 12.6V 60A lithium battery protection board

Charging voltage: DC 12.6V~13.6V

Continuous discharge current: 60A maximum (if the heat dissipation environment is not good, please reduce the load current)

Continuous charging current: up to 20A

Balance Version Product size: 41*61*4mm

Enhance Version Product size: 41*55*4mm

Applicable choice: applicable to the nominal voltage of 3.7V, fully charged 4.2V lithium battery (including 18650, 26650, polymer lithium battery), can be drilled below 170W

Note 1: Successfully start the drill requires 3 10C-20C power batteries, or 6 5C-10C power batteries (recommended power battery models: sony vtc4, vtc4A, vtc5A, vtc6) OV and 12.6V cable, use Copper wire of 3 square millimeters or more (nickel sheets cannot be used)

Note 2: Strictly connect 0V, 4.2V, 8.4V, 12.6V according to the diagram. Do not touch any components on the board when soldering the wire. Do not intentionally short circuit.

Note 3: When soldering the battery for the first time or when charging is in progress, as long as the single battery exceeds 4.2V, the "430" resistor will heat up and discharge (discharge to about 4.19V to stop heating). If the "430" resistor is severely hot, check if the wrong line is connected.
