3S 30A

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

Enhanced version: Suitable for electric drills with a starting current of 60A or less, power below 130W, or resistive loads below 378W

Balanced 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: Strictly follow the wiring of the diagram 0V, 4.2V, 8.4V, 12.6V, do not touch any components on the board when soldering the wire, 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)

3S 40A

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 starting 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 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 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: 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).
