Product Description :

3S 40A  Lifepo4
BMS 3S 40A  Balance 18650 3.2V LiFePO4/3.7V Li-ion  battery protection board /iron lithium BMSwith equalizing startable drill
 
3 S10.8V 40A lithium iron battery protection board (with recovery function -AUTO Recovery)
 
Scope of application: Suitable for nominal voltage 3.2V, full-voltage 3.6V iron-lithium batteries (including 18650, 26650, lithium polymer batteries, there is no limit on the size)
 
Product Size: 41*55*3.4mm (Standard Edition), 41*60*3.4mm (Balanced Edition)
 
Product Weight: 8.6g (Standard Edition), 9.4g (Balanced Edition)
 
Charging voltage: 10.8V - 12V
 
Continuous discharge current (upper limit): 40A (If the cooling environment is not good, reduce the load current use)
 
Continuous charge current (upper limit): 20A
 
Standard Version: Suitable for electric drills with a starting current of 80A or less and power of 150W or less.
 
Balanced Version: Suitable for electric drills with a starting current of 80A or less and power of 150W or less, with a balanced charging function.
 
This is Balance Version!
 
Note 1: The successful start of electric drill requires three 15C-20C power batteries, or six 10C-15C power batteries (ordinary 18650 can not start drill! ! !).
 
Note 2: Connect 0V, 3.6V, 7.2V, and 10.8V according to the diagram strictly. Do not intentionally short circuit.
 
 
Note 3: When the battery is charged, the "360" resistance heating is normal, indicating that the equalizing circuit is working; if the "360" resistance is also heating in the non-charging state, please check whether the wrong wiring is connected.
 
For some customers with poor electronic foundation, please explain: Don't mix good battery and bad battery together! The capacity/internal resistance of the 3 groups of batteries is as close as possible! (2 good batteries + 1 bad battery use effect = 3 battery use effect).

 

Package Include:

1*LiFePO4 Board

The conditions for successfully starting the drill:

1, need three 15C-20C power batteries or six 10C-15C power batteries (ordinary 18650 can not start drill)

2. The distance between the battery pack and the protection board should be as short as possible and the core should be as thick as possible.

3, When welding the battery for the first time, do not connect any output and equipment to the output.

4. If you still cannot start, please contact us first.

3S 40A Li-ion

 

3S 40A 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: 42 * 60 * 3.4mm (balanced version)

Product weight: 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

Balance version: suitable for starting current below 80A, power 135W below the drill.

Note 1: The successful start of the electric drill requires 3 15C-20C power batteries, or 6 10C-15C power batteries (ordinary 18650 can not start drill! ! !).
 
Note 2: Connect 0V, 4.2V, 8.4V, 12.6V,in strict accordance with the diagram. Do not intentionally short circuit.
 
 
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.

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).
