3S 12.6V 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)
Size:41*55*3.4mm(Enhanced version),41*62*3.4(Balanced version).
Weight:8.8g(Enhanced version),9.8g(Balanced version).
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: When you wiring 0V, 4.2V, 8.4V, 12.6V, plese 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.
