Description:
Note: If you need other battery protection board,please click here.
Standard version: Suitable for electric drills with a starting current of 120A or less and a power of 260W or less.
Balanced version: Suitable for electric drills with starting current below 120A and power below 260W, with balanced charging function.
3S 12.6V 60A lithium battery protection board:
Scope of application: Suitable for lithium batteries with nominal voltage of 3.7V and full voltage of 4.2V (including 18650, 26650, polymer lithium batteries, no size limit).
Product size: 41*55*3.4mm (standard version), 41*62*3.4mm (balanced version)
Product weight: 8.8g (standard version), 9.8g (balanced version)
Charging voltage: 12.6V - 13.6V
Continuous discharge current (upper limit): 60A (If the heat dissipation environment is not good, please reduce the load current)
Continuous charging current (upper limit): 15A
Note 1: Successfully start the drill requires 3 15C-20C power batteries, or 6 10C-15C power batteries (recommended power battery models: SONY VTC4, VTC4A, VTC5A, VTC6); 0V and 12.6V cable, Use copper wire above 4 mm2 (cannot use nickel plate! ! !).
Note 2: Strictly follow the wiring of the diagram 0V, 4.2V, 8.4V, 12.6V, do not intentionally short circuit.
Note 3: When charging the battery, the "430" resistance heating is normal, indicating that the equalization circuit is working; if the "430" resistor is also hot in the uncharged state, please check if the wrong line is connected.
For some customers with poor electronic foundation, please explain: Do not mix good battery and poor battery! The closer the capacity/internal resistance of the 3 batteries is, the better! (The effect of 2 good batteries + 1 poor battery) = 3 use of poor battery).
