Product description

Description: 3S 12.6V 40A Iron Lithium Battery protection board Scope: Nominal voltage of 3.2V, 3.6V Iron Lithium Battery (including 18650,26650, polymer lithium battery) Product Size: 41 * 55 * 3.4mm ( Standard Version ) , 41 * 60 * 3.4mm (Balanced version) Product weight: 8.6g (standard version), 9.4g (balanced version) Charging voltage: 10.8V - 12V Continuous discharge current (upper limit): 40A (if the cooling environment is not good, please reduce the load current use) Continuous charge current (upper limit): 20A Package include: 1* Iron Lithium Battery Charger Protection Board Standard version: suitable for starting current below 80A, power 150W below the drill.(Not balanced function) Balanced version: suitable for starting current below 80A, power 150W below the drill.(with balance) Note 1: The successful start of the drill requires three 15C-20C power battery, or six 10C-15C power battery (ordinary 18650 can not start the drill!!). Note 2: strictly according to map wiring 0V, 3.6V, 7.2V, 10.8V, do not deliberately short circuit. Note 3: When charging the battery, the "360" resistance heating is normal, indicating that the equalization circuit is working; if the "360" resistance is also heating in the non-charging state, please check whether the wrong line is connected. 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).
