Range: Rated Voltage 3.6V, 3.7V lithium battery (including 18650.26650, lithium polymer battery)
Product size: 42 * 60 * 3.4mm (balanced version)
Product weight: 9.8g (balanced version)
Charging voltage: 12.6V - 13.6V
Direct discharge current (upper limit): 40A (if the cooling environment is not good, reduce the use of charging current)
Direct charging current (upper limit): 20A
Improved version: Suitable for electric drill with starting current below 80A and power below 130W. (no balanced function)
Balanced version: Suitable for electric drill with starting current below 80A and power below 170W. (with load balanced function)
Note:
Note 1: To successfully start the drill requires three 15C-20C power batteries, or six 10C-15C power batteries (ordinary 18650 battery cannot start the drill!!).
Note 2: When wiring 0V, 4.2V, 8.4V, 12.6V, do so strictly according to the wiring diagram. Don't deliberately short-circuit it.
Note 3: When the battery is charging, the resistance heating "430" is normal, which means that the balance circuit is working. If the resistor "430" is also heating up without charging, check if the wrong cable is connected.
Note 4: Do not use a mixture of good battery and poor battery, make sure each battery is the same in capacity and internal resistance.
