Precautions:
 
Strictly according to the diagram wiring: 0V(B-)3.7V(B1)7.4V(B2)11.1V(B ), Do not deliberately short circuit.
After the line is connected, Need to charge first, then have output.
When the battery is connected in series with 3 groups, Please ensure that the voltage of each battery is the same. If not same, please fill in each set of batteries and then use.
Do not mix the good battery and the battery.
The capacity of the battery internal resistance is closer will be better.
Attention: Do not mix the good battery and poor battery to use. The internal resistance of 3 battery capacity are closer will be better. Please buyers know the professional knowledge of this module before buying
 
 
Note:
 
Due to different producing batches, product details might be a little different. If you minding the difference, please buy it carefully.
Please allow 1-5mm differs due to manual measurement.

Description:
3S 12.6V 40A lithium battery protection board (comes with recovery function-AUTO Recovery)
 
Scope: Nominal voltage of 3.7V lithium battery (including 18650,26650, polymer lithium battery)
Product Size: 41 * 55 * 3.4mm (Enhanced Version), 41 * 60 * 3.4mm (Balanced version)
Product weight: 8.8g (enhanced version), 9.8g (balanced version)
Charging voltage: 12.6V - 13.6V
Continuous discharge current (upper limit): 40A (if the cooling environment is not good, please reduce the load current )
Continuous charge current (upper limit): 20A
 
Enhanced version:Suitable for electric drill with starting current below 80A and power below 130W .(without balanced function)
Balanced version: Suitable for electric drill with starting current below 80A and power below 170W .(with balanced charging function)
 
Note 1: To successful starting the drill requires three 15C-20C power batteries, or six 10C-15C power batteries (ordinary 18650 battery can not start the drill!!).
Note 2: When you wiring 0V, 4.2V, 8.4V, 12.6V, please do it strictly according to the wiring diagram.Do not deliberately make it 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,please check if the wrong wire is connected.
 
Note 4: Do not use a mix of good battery and poor battery,please make sure 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).
