3S/4S 40A 60A Li-ion Lithium Battery Charger Protection Board 18650 BMS For Drill Motor 11.1V 12.6V/14.8V 16.8V Enhance/Balance
3S 60A/30A 4S 40A Li-ion Lithium Battery Charger Protection Board BMS 3S/4S For Drill Motor 16.8V Battery Balancer Power Bank
 
 3S 60A lithium battery protection board
Scope: Suitable for lithium battery with 3.7V nominal voltage and 4.2V limited charge voltage. (includes 18650,26650, polymer lithium battery)
Charging voltage: 12.6V - 13.6V
Continuous discharge current (upper limit): 60A (if the cooling environment is not good, please reduce the load current)
Continuous charge current (upper limit): 15A
Enhanced version: suitable for electric drill with starting current below 120A and power below 260W .(without balanced charging function)
 
Balanced version: suitable for electric drill with starting current below 120A and power below 260W .(with balanced charging function)
Note 1: To successful starting the drill requires three 10C-20C power batteries, or six 5C-10C power batteries ( recommended battery:SONY VTC4,VTC4A,VTC5A,VTC6).Ordinary 18650 battery can not start the drill!Requires 0V and 12.6V copper wire which is no less than 4SQMM(Can not use nickel!!!).
 
Note 2: 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.
 
 3S 30A lithium battery protection board    
Feture:
Scope: Suitable for ternary lithium battery with nominal voltage of 3.7V and full voltage of 4.2V (including 18650, 26650, polymer battery, no size limit)
Charging voltage: 12.6V-13.6V
Continuous discharge current (upper limit): 30A If the heat dissipation environment is not good, please reduce the load current.
Continuous charging current (upper limit): 20A
Standard version: Suitable for electric drills with a starting current of 60A or less, power below 130W, or resistive loads below 378W
Equilibrium version: Suitable for electric drills with starting current below 60A, power below 130W, or resistive load below 378 with balanced charging function.
Note 1: Three 10C-20C power batteries or six 5C-10C power batteries are required to successfully start the drill (recommended power battery model: VTC4 VTC4A VTC5A VTC6)
Note 2: do not intentionally short circuit
Note 3: When soldering the battery for the first time or charging, as long as the single battery exceeds 4.2V, the 430 resistor will heat up and discharge (discharge to about 4.19V to stop heating). If the 430 resistor is severely heated (heat is not enough to touch, please check if the wrong line is connected)
 
4S 16.8V 40A lithium battery protection board
Scope: Nominal voltage of 3.6V, 3.7V lithium battery (including 18650,26650, polymer lithium battery)
Charging voltage: 16.8V - 18.1V
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
 
Note:this item is Balanced version.If you need other Version,please contact us.The 3 version price is different
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 220W below the drill.(with balance)
Enhanced version Purchase link:Please click here
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, 16.8V, 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: 4 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.
