2Pcs 3S 40A Li-ion Lithium Battery Charger Protection Board PCB BMS For Drill Motor 11.1V 12.6V Lipo Cell Module With Ba

Description Suitable for starting current below 80A power 135W below the drill with balance 3S 12 6V 40A lithium battery protection board comes with recovery function AUTO Recovery Scope Nominal voltage of 3 6V 3 7V lithium battery including 18650 26650 polymer lithium battery Product Size 41 60 3 4mmProduct weight 9 8gCharging voltage 12 6V 13 6VContinuous discharge current upper limit 40A if the cooling environment is not good please reduce the load current use Continuous charge current upper limit 20A Note 1 The successful start of the drill requires three 15C 20C power battery or six 10C 15C power battery ordinary 18650 cannot start the drill Note 2 Strictly according to map wiring 0V 4 2V 8 4V 12 6V do not deliberately short circuit Note 3 When soldering the battery for the first time or while charging as long as the single battery exceeds 4 2V the 430 resistor will heat up and discharge discharge to about 4 19V to stop heating If the 430 resistor is severely hot check if the wrong line is connected 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 ProjectMin Typ Max UnitsNotesConsuming current121824uA Overcharge protection voltage4 24 254 3V Balanced starting voltage4 17
