After the line is connected, Need to charge first, then have output. When the battery is connected in series with 3 groups, Please ensure that the voltage of each battery is the same. If not same, please fill in each set of batteries and then use. Do not mix the good battery and the battery. The capacity of the battery internal resistance is closer will be better. Attention: Do not mix the good battery and poor battery to use. The internal resistance of 3 battery capacity are closer will be better. Please buyers know the profeional knowledge of this module before buying 3S 40A Balanced Balanced version: suitable for starting current lower than 80A and power lower than 135W of drill bit. This Balance is a new upgrade: 1. Enhance anti-interference function, 2. Reduce high current heat by 30%, 3. The starting power is increased from 135W to 170W (3S40A) 3S 40A 12.6V 40A lithium battery protection board (with recovery function - automatic recovery) Scope of application: nominal voltage 3.6V, 3.7V lithium battery (including 1865026650, polymer lithium battery) Product size: 42 * 55 * 3.4mm Balanced version: 42 * 60 * 3.4mm Product weight: 8.8g Balance version: 9g Charging voltage: 12.6V - 13.6V Continuous discharge current (upper limit): 40A (if the cooling envment is bad, please reduce the load current) Continuous charging current (upper limit): 20A Note 1: Three 15C-20C power batteries or six 10C-15C power batteries are required for the succeful startup of the drilling rig (ordinary 18650 cannot start the drilling rig!!); 0V and 12.6V cables, use copper wire of more than 3mm2 (nickel plate is not allowed!!)! Note 2: Wiring 0V, 4.2V, 8.4V, 12.6V strictly according to the map, and do not intentionally short circuit. Note 3: When using the load of the brush motor, please try to connect the non-polar capacitor (withstand voltage higher than 25V, capacity 10uF-100uF) to the positive and negative terminals of the motor to prevent reverseke of the motor. Break the MOS tube. Note 4: 3 groups of batteries are connected in series. Please ensure the voltage of each group of batteries. If they are different, please charge each battery separately and then use them in series. Discharge test, the battery voltage of the battery pack drops faster. Basic explanation for some bad electronic customers: balanced charging is only an auxiliary function. Try not to mix good batteries with poor ones! The capacity/resistance of 3 sets of batteries shall be as close as poible! (2 good batteries+1 poor battery use effect=3 poor battery use effect). Package includes: 1 * 3S 40A protection plate

3S 60A Enhanced

Description:

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 envment 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 succeful 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 le 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.
