3S 40A - Lithium Battery Charger Protection Board PCB BMS for Drill Motor 11.1V 12.6V Cell Module

Continuous discharge current ( limit): 40A (if the cooling environment is not good reduce the load current ) Continuous charge current ( limit): 20A Color: green Material: PC + metal Enhanced version:Suitable for electric drill with starting current 80A and power 130W .(without balanced function) Note 1: To successful starting the drill requires three 15C-20C power batteries or six 10C-15C power batteries (ordinary can not start the drill!!). Note 2: When you wiring 0V 4.2V 8.4V 12.6V do it strictly according to the wiring .Do not deliberately short circuit. Note 3: When the battery is charging the 430 resistance heating is normal it means the balance circuit is working.If the 430 resistance is also heating without charging check if the wrong wire is connected. Note 4: Do not use a mix of good battery and poor battery make each battery is the same in capacity and internal resistance. For some of the poor basis of electronic customers to explain: balanced charge is only auxiliary functions try not to put a good battery and poor battery mixed together! 3 sets of battery capacity / resistance closer to the better! (2 good battery +1 Poor battery use effect = 3 poor battery use effect). Package Include: 1* Enhanced version PCB Only the above package content other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
