- MS 3 series 12.6V 20A lithium battery protection board (with recovery function autorecovery)
- 3 series 12.6V 20A lithium battery protection board (with recovery function autorecovery)
- Scope of application: lithium battery with nominal voltage of 3.6V and 3.7V (including18650,26650 and polymer lithium battery)
Product size: 59 * 20 * 3.4mm
Product weight: 4.3g
Charging voltage: 12.6V - 13.0V
Continuous discharge current (upper limit): 20A (if the heat dissipation environmentis bad, please reduce the load current)
Continuous charging current (upper limit): 10A
Standard Version: applicable to electric drills with starting current below 40A andpower below 65w.

Note 1: Three 15c-20c power batteries or six 10c-15c power batteries are required tosuccessfully start the electric drill (the ordinary 18650 cannot start the electric dril!!!);lf the battery is too small or the power of the electric drill is too large, please contactthe shopkeeper to tell you the solution.
Note 2: Connect 0V,4.2V,8.4v and 12.6V in strict accordance with the diagram. Do notintentionally short circuit.
Note 3: For loads with brush motors, a capacitor (10uf-1000uf) must be connected inparallel at the positive and negative terminals of the motor to prevent the reversepeak voltage generated by the motor from interfering with the protection board orbreaking down the MOS tube.
Note 4: when three batteries are connected in series, please ensure that the voltageof each battery is the same. If not, please fill each battery separately and use it inseries...
- During the discharge test, the battery whose voltage drops faster is a poor battery.
- For some customers with poor electronic foundation, please explain: do not mix goodbatteries with poor batteries! The closer the capacity / internal resistance of the threebatteries is, the better ( Use effect of 2 good batteries + 1 poor battery = use effectof 3 poor batteries).

Conditions for successful start of electric drill:
1.Three 15c-20c power batteries or six 10c-15c power batteries are required (Ordinary 18650 cannot start the electric drill!!!)
2.The distance between the battery pack and the protection board shall be as shortas possible, and the wire cores shall be in phase as far as possible.
3. When welding the battery for the first time, the output terminal shall not beconnected with any load or any equipment.
4. lf it still cannot be started, please contact the shopkeeper again to tell you thesolution.
Standard Version: applicable to electric drills with starting current of 40A and powerbelow 65w
5. If the battery is too small or the power of the electric drill is too large, which makes itimpossible to start, please contact the shopkeeper again to tell you the solution.
