The conditions for successfully starting the drill:
1, need three 15C-20C power batteries or six 10C-15C power batteries (ordinary 18650 can not start drill)
2. The distance between the battery pack and the protection board should be as short as possible and the core should be as thick as possible.
3, When welding the battery for the first time, do not connect any output and equipment to the output.
4. If you still cannot start, please contact us first.
4 S 14.4V 40A lithium iron battery protection board (with recovery function -AUTO Recovery) Scope of application: Suitable for nominal voltage 3.2V, full-voltage 3.6V iron-lithium batteries (including 18650, 26650, lithium polymer batteries, there is no limit on the size) Product Size: 44*55*3.4mm Charging voltage: 14.4V - 16V Continuous discharge current (upper limit): 40A (If the cooling environment is not good, reduce the load current use) Continuous charge current (upper limit): 20A Suitable for electric drills with starting current less than 80A and power less than 200W. Note 1: The successful start of the drill requires four 15C-20C power batteries, or eight 10C-15C power batteries (ordinary 18650 can not start the drill! ! !). Note 2: Connect 0V, 3.6V, 7.2V, 10.8V, 14.4V in strict accordance with the diagram. Do not intentionally short circuit. Note 3: When the battery is charged, the “360” resistance heating is normal, indicating that the equalizing circuit is working; if the “360” resistance is also heating in the non-charging state, please check whether the wrong wiring is connected. For some customers with poor electronic foundation, please explain: Do not mix good battery and bad battery together! The capacity/internal resistance of the 4 batteries should be as close as possible (3 good batteries + 1 bad battery = 4 battery use effect). Package Include: 1* LiFePO4 Board
