Product size: 59 * 20 * 3.4mm Product weight: 4.3g
Charging voltage: 12.6V-13.0V
Note1:
Continuous discharge current (upper limit): 20A (If the cooling environment is not good, please reduce the load current for use)
Continuous charging current (upper limit): 10A standard version: suitable for electric drills with starting current below 40A and power below 65W.
Note 2: Strictly follow the wiring diagram for 0V, 4.2V, 8.4V, and 12.6V, and do not intentionally short circuit.
Note 3: When carrying a load with a brush motor, a capacitor (10uF-1000uF) must be connected in parallel at the positive and negative terminals of the motor to prevent the reverse peak voltage generated by the motor from interfering with the protection board or breakdown of MOS tubes.
Note 4: When connecting three sets of batteries in series, please ensure that the voltage of each set of batteries is the same. If it is different, please fully charge each set of batteries separately before using them in series.. The group of batteries with a rapid voltage drop during discharge testing is a poor battery.
