2S 7.4V 8.4V 20A  lithium battery protection board with balance:
 
Applicable scope: Suitable for lithium batteries with nominal voltage of 3.7V and full voltage of 4.2V (including 18650, 26650, polymer lithium batteries, without limitation on the dimensions)
 
Product Size: 45*15*3.4mm (Standard), 48*20*3.4mm (Balanced)
 
Product Weight: 2.9g (Standard Edition), 3.7g (Balanced Edition)
 
Charging voltage: 8.4V - 9.0V
 
Continuous discharge current (upper limit): 20A (If the cooling environment is not good, reduce the load current use)
 
Continuous charge current (upper limit): 10A
 
Standard Edition: Suitable for starting drills with currents up to 25A below 50W, or resistive loads below 168W.
 
Balanced version: Suitable for starting currents below 25A and below 50W power drills, or resistive loads below 168W, with balanced charging function.
 
Note 1: The successful start of the drill requires two 10C-20C power batteries, or four 5C-10C power batteries (ordinary 18650 can not start the drill! ! !).
 
Note 2: Connect 0V, 4.2V, 8.4V according to the diagram strictly. When connecting the battery for the first time, it needs to be charged before output.
 
 
Note 3: When the battery is charged, “430” resistance heating is a normal phenomenon, indicating that the equalizing circuit is working; if the “430” resistance is also heating in the state of not charging, please check whether the wrong line is connected.
 
For some customers with poor electronic foundation, please explain: Do not mix good batteries and bad batteries together! The capacity/internal resistance of 2 batteries should be as close as possible! (1 good battery + 1 bad battery = 2 battery use effect).

3S 12.6V 40A lithium battery protection board with balance:
 
Scope: Nominal voltage of 3.6V, 3.7V lithium battery (including 18650,26650, polymer lithium battery)
 
Product Size: 42 * 55 * 3.4mm (Standard Version / Enhanced Version), 42 * 60 * 3.4mm (Balanced version)
 
Product weight: 8.8g (standard / 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 use)
 
Continuous charge current (upper limit): 20A
 
 
Standard version: suitable for starting current below 60A, power 100W below the drill.(Not balanced function)
 
Enhanced version: for starting current below 80A, power 135W below the drill.(Not balanced function)
 

Balanced version: suitable for starting current below 80A, power 135W 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, 4.2V, 8.4V, 12.6V, do not deliberately short circuit.
 
 
Note 3: When the load of the brush motor is used, try to connect a non-polar capacitor (withstand voltage above 25V, capacity 10uF-100uF) to the motor's positive and negative terminals to prevent the reverse spike from the motor. Break the MOS tube.
 
Note 4: 3 groups of batteries in series, please ensure that the voltage of each group of batteries, if not the same, please fill each battery separately and then use in series. The The Discharge test, the voltage drop faster battery that group is poor battery.
 
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).
