What are the common failures of lithium battery protection boards? 1, no display, low output voltage, can not afford load 2, no charge 3, no internal resistance, internal resistance large 4, no resistance 5, overcurrent 6, do not decode lithium battery protection plate broken how to repair and repair? Lithium battery protection board is broken, you can charge it with charger to see if the protector can be activated. If you can't make it, it is definitely broken. It may be damaged by electronic components, and it is possible to reset it! However, if the protected plate is broken, it should be 0V.

If you have access to a lithium battery protection board, let's discuss why lithium battery protective plates have no charging protection, I hope to bring some useful help. What are the cases of lithium battery protection plates without charging protection? First, see the three-way parameters: routine is 2.8 ~ 4.

65V1. It may be voltage overcharge, overcharge, overcurrent, short circuit, over temperature. 2.

Do not open the charging MOS tube with a multimeter table 3. If the lithium battery protective plate is LED, it cannot be charged and discharge is a 0.5 second alarm.

4. If the lithium battery protection board is the host machine, the host machine can be connected. View Protection Status 5.

Lithium battery protection board is a weak point switch, please check if the weak switch is turned off.
