Description:

Suitable for starting current below 80A, power 135W below the drill. (with balance) 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 * 3.4mm

Product weight: 9.8g

Charging voltage: 12.6V - 13.6V

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

Note 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
