The lithium battery protection circuit board is mainly composed of protection IC (overvoltage protection) and MOS tube (overcurrent protection), and is a device used to protect the safety of lithium battery cells.
Jump-starting the BMS is a process that can be used to revive a lithium-ion battery pack that has a 0V output. According to the information above, this process can be done in cases where the BMS has tripped and is preventing the battery from functioning normally. To jump-start the BMS, you need to short the B- and P- connections on the BMS.
Generally speaking, however, most BMS will completely disable the battery (go into protection mode) if the cells fall below around 2.4 volts or so. Once this happens, both charging and discharging is disabled. The only way to solve this is to access the individual cell groups and charge them to within range of the BMS.
First, locate the B- and P- connections on the BMS. They are usually marked on the circuit board or can be found in the wiring diagram for the battery pack. Once you have located the connections, carefully touch the metal wire or other conductive material to both connections at the same time.
Being required to be attached to a charger for the BMS to wake up is the safest way to operate a lithium-ion battery. It means that the load wont randomly turn back on, and it means that the battery cells will for sure no not be put under a load that will damage the cells.
There are several reasons a BMS would end up in protection mode and sleep mode is basically an extended version of protection mode. For example, when a lithium-ion battery is at around 30 percent capacity and is then put under a sudden, high load, the battery cells can momentarily dip below the LVC (Low Voltage Cutoff).
Analysis of common problems and causes of lithium battery packs
The lithium-ion battery pack cannot be charged when charging. The possible reasons are that the charger is reversed or the charger is faulty; the protection of the protection board is not restored, or the protection board is defective; the battery pack and the electrical appliance are externally disconnected.

Why is my Lithium battery Discharging and shutting off at night?
1. The B1 at the shunt have to be after the BP-100, so the BMV also gets shut down if the BMS disconnects all loads. 2.
