Safety hazards of lithium batteries without protection board:
The lithium battery pack does not have a protective plate to over-discharge the lithium battery and affects the lifespan. It is very dangerous to use the lithium battery pack without a protective board. The lithium battery has strong activity. If there is no protective board, it is easy to explode if it is short-circuited or other factors affecting it. Multiple protective boards can enable the battery to automatically cut off the circuit during overcurrent or overvoltage without damaging the battery or exploding.
If the lithium battery does not have a protective plate, the life of the lithium battery will not only be affected, but also in serious cases will be dangerous. In a relatively mild case, it will damage the battery and affect its service life. In severe cases, it will cause the battery to bulge. In severe cases, liquid leakage, loose pressure, explosion or fire.
The lithium battery pack protection plate is a charge and discharge protection for series lithium battery packs. When fully charged, it can ensure that the voltage difference between each single battery is less than the set value (generally ±20mV), thereby achieving uniform charging of each single battery in the battery pack, effectively improving the charging effect under the series charging mode. At the same time, the overvoltage, undervoltage, overcurrent, short circuit and overtemperature states of each single battery in the battery pack are detected to protect and extend the battery service life. Undervoltage protection allows each single battery to avoid damage caused by overdischarge during discharge.
