(Drill Motor Lithium Battery Protection Module -3S 12.6V 40A )
개요
- 본 제품은 드릴 모터 리튬 배터리 보호 모듈 -3S 12.6V 40A입니다.
- 드릴과 같은 모터를 배터리로 동작시키기 위해서 필요한 제품으로 연속적으로 40A를 공급할 수 있습니다.
- 3S 12.6V 40A 등급입니다.
- 알림: 밸런싱 기능은 없으므로 배터리 상태가 좋지 않은 배터리를 섞어서 연결하지 마십시오.

Suitable for starting current below 80A, power 135W below the drill. 3S 12.6V 40A lithium battery protection board (comes with recovery function-AUTO Recovery)Scope: Nominal voltage of 3.6V, 3.7V lithium battery (including 18650,26650, polymer lithium battery)Product Size: 41 * 60 * 3.4mmProduct weight: 9.8gCharging voltage: 12.6V - 13.6VContinuous discharge current (upper limit): 40A (if the cooling environment is not good, please reduce the load current use)Continuous charge current (upper limit): 20ANote 1: The successful start of the drill requires three 15C-20C power battery, or six 10C-15C power battery (ordinary 18650 cannot start the drill!!).Note 2: Strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, do not deliberately short circuit.Note 3: When soldering the battery for the first time or while 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 hot, check if the wrong line is connected.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).

Troubleshooting: Fault phenomenon Fault check and cause Approach Unable to charge Measure the voltage of the three groups of batteries. When one of the battery voltages exceeds 4.25V, the protection board will activate overcharge protection. Pair the battery pack well, do not mix the good battery
and the bad battery (normal function)Unable to discharge Measure the voltage of the three battery packs.
When one of the battery voltages is lower than 2.7V,
the protection board will activate the over-
discharge protection.Pair the battery pack well, do not mix the good battery
and the bad battery (normal function)Charging/discharging failure OV, 4.2V, S.4V, 12.6V miswired Rewiring or replacing a new board (human failure) Overcharge/overdischarge failure OV, 4.2V, 8.4V, 12.6V miswired Rewiring or replacing a new board (human failure) Discharge protection Check that the battery pack has sufficient
discharge capability and check that the load's
starting current exceeds the overcurrent
protection current of the protection board.Replace the battery pack with a higher discharge
capacity, or a protective plate with a larger current
(super working range)Component soldering There is no connection between one of the
components and the PCB pad.Repair welding Component welding There is a short circuit between two or more pins
of the component.Remove the component and re-weld Electrostatic breakdown A In the unpowered state, measure the G, D, and S
poles of the MOSFET. If the forward and reverse
resistances of any two pins are 0Q, it indicates
that it has broken down.Remove the replacement MOS tube Electrostatic breakdown B Remove the MOS tube and measure the
resistance of the G and D, G and S poles of the
MOS tube. If there is a resistance indicating that it
has broken down, the resistance should be
infinite.Remove the replacement MOS tube
