Troubleshooting:
Fault phenomenon
Fault check and cause
The solution
Unable to charge
Measuring the voltage of 4 groups of batteries.
Pair the battery pack well, do not mix
when one of the battery voltages exceeds 4.25V,
the good battery and the bad battery.
the protection board will activate overcharge protection.
Unable to discharge
Measuring the voltage of 4 groups of batteries.
Pair the battery pack well, do not mix
when one of the battery voltages is lower than 2.7V,
the good battery and the bad battery.
the protection board will activate the over-discharge
protection.
Charging discharging
OV, 4.2V, S.4V, 12.6V, 16.8V miswired
Rewire or replace the new board
failure
(human failure, no warranty)
Overcharge overdischarge
OV, 4.2V, 8.4V, 12.6V, 16.8V miswired
Rewire or replace the new board
failure
(human failure, no warranty)
Discharge protection
Check that the battery pack has sufficient discharge
Replace the battery pack with a higher
capability and check that the load s starting current
discharge capacity, or a protective
exceeds the overcurrent protection current of the
plate with a larger current
protection board.
(super working range)
Component soldering
There is no connection between one of the components
Repair welding
and the PCB pad.
Component welding
There is a short circuit between two or more pins of the
Remove the component and re-weld
component.
Electrostatic breakdown A
In the unpowered state, measure the G, D, and S
Remove the replacement MOS tube
poles of the MOSFET. If the forward and reverse
resistances of any two pins are 0Q,
it indicates that it has broken down.
Electrostatic breakdown B
Remove the MOS tube and measure the resistance
Remove the replacement MOS tube
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.
Package includes:
3 x Battery Protection Board
