3S/4S 40A 60A Li-ion Lithium Battery Charger Protection Board 18650 BMS

brand: DIYTECH SKU:DT4648
Regular price $1.99

3S 40A Balance/Enhance

Description:

3S 12.6V 40A lithium battery protection board (comes with recovery function-AUTO Recovery)
Scope: Nominal voltage of 3.7V lithium battery (including 18650,26650, polymer lithium battery)
Product Size: 41 * 55 * 3.4mm (Enhanced Version), 41 * 60 * 3.4mm (Balanced version)
Product weight: 8.8g (enhanced version), 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 )
Continuous charge current (upper limit): 20A

Enhanced version: Suitable for electric drill with starting current below 80A and power below 130W .(without balanced function)
Balanced version: Suitable for electric drill with starting current below 80A and power below 170W .(with balanced charging function)

Note 1: To successful start, the drill requires three 15C-20C power batteries, or six 10C-15C power batteries (ordinary 18650 battery can not start the drill!!).
Note 2: When you wiring 0V, 4.2V, 8.4V, 12.6V, please do it strictly according to the wiring diagram. Do not deliberately make it a 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.
Note 4: Do not use a mix of the good battery and poor battery, please make sure each battery is the same in capacity and internal resistance.

For some of the poor basis of electronic customers to explain: a 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).

4S 40A Balance/Enhance

Description:

4S 16.8V 40A lithium battery protection board (comes with recovery function-AUTO Recovery)
Scope: Nominal voltage of 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

Enhanced version: suitable for electric drill with starting current below 80A and power below 180W .(without balanced function)
Balanced version: suitable for electric drill with starting current below 80A and power below 230W .(with balanced charging function)

Note 1: To successful start, the drill requires three 15C-20C power batteries, or eight 10C-15C power batteries (ordinary 18650 battery can not start the drill!!).
Note 2: When you wiring 0V, 4.2V, 8.4V, 12.6V, 16.8V, please do it strictly according to the wiring diagram. Do not deliberately make it a 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.
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 Discharge test, the voltage drop faster battery that group is a poor battery.
