Features:
- 1. Scope of application: Suitable for lithium batteries with a nominal voltage of 3.7V and full voltage of 4.2V (including 18650, 26650, polymer lithium batteries, no size limit).
- 2. Product size: 41*62*0.34mm (balanced version)
- 3. Charging voltage: 12.6V - 13.6V
- 4. Continuous discharge current (upper limit): 60A (If the heat dissipation environment is not good, please reduce the load current)
- 5. Continuous charging current (upper limit): 15A
- 6. Balance version: Suitable for electric drills with starting current below 120A and power below 260W, with a balanced charging function.
- - Note 1: Successfully starting the drill requires 3 15C-20C power batteries, or 6 10C-15C power batteries (recommended power battery models: 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, and 12.6V, and 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.
- - Note 4: For some customers with poor electronic foundations, 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).
