3S 12.6V 40A lithium battery protection board (comes with function-AUTO )
: Nominal voltage of 3.7V lithium battery (including 18650,26650, polymer lithium battery)
Product Size: 41 * 55 * 3.4mm (Enhanced Version)
Charging voltage: 12.6V - 13.6V
Continuous discharge current (upper limit): 40A (if the cooling environment is not good, reduce the load current )
Continuous charge current (upper 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 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 ! 3 sets of battery capacity / resistance closer to the better! (2 good battery +1 Poor battery use effect = 3 poor battery use effect).
