3 series 12.6V40A lithium battery protection board
Scope of application: suitable for lithium batteries with a nominal voltage of 3.7V and a full voltage of 4.2V
(Including 18650, 26650, polymer lithium battery, there is no restriction on external dimensions)
Product size: 41*55*3.4mm (enhanced version), 41*60*3.4mm (balanced version)
Product weight: 8.8g (enhanced version), 9.8g (balanced version)
Charging voltage: 12.6V~13.6V
Continuous discharge current (upper limit): 40A (If the heat dissipation environment is not good, please reduce the load current to use)
Continuous charging current (upper limit): 20A
Enhanced version: suitable for electric drills with starting current below 80A and power below 170W.
Balanced version: suitable for electric drills with starting current below 80A and power below 170, with equalizing charging function.
Note 1: Successful start of the electric drill requires 3 10C-20C power batteries, or 6 5C-10C power batteries (recommended power battery models: SONY VTC4, VTC4A, VTC5A, VTC6), 0V and 12.6V connection lines, use Wires of more than 3 square millimeters (Nickel sheets cannot be used!).
Note 2: Wiring 0V, 4.2V, 8.4V, 12.6V strictly according to the diagram, and do not touch any components on the board when welding the wire, and do not intentionally short-circuit.
Note 3: When the battery is being welded for the first time or is being charged, as long as a 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 seriously hot (you can't touch it when it is too hot), please check whether it is connected to the wrong wire.
Conditions for successfully starting the electric drill:
1. Need 3 15C-20C power batteries or 6 10C-15C power batteries. (Ordinary 18650 can't start the electric drill!!)
2, 0V and 12.6V connection wires , use copper wires of more than 3 square millimeters, the shorter the length, the better.
