The lithium battery protection board is the charge and discharge protection for the series-connected lithium battery pack; when fully charged, it can ensure that the voltage difference between the individual cells is less than the set value (generally ±20mV), so as to realize the equal charge of each single cell of the battery pack. , effectively improving the charging effect in the series charging mode; at the same time, it detects the overvoltage, undervoltage, overcurrent, short circuit, and overtemperature status of each single cell in the battery pack to protect and prolong the battery life; undervoltage protection makes each A single-cell battery is used to avoid damage to the battery due to overdischarge.

Buried hole: Buried hole, the connection of any circuit layer inside the PCB but not conducted to the outer layer. This process cannot be achieved by drilling after bonding. Drilling must be performed on individual circuit layers. First, the inner layer must be partially bonded and then electroplated. Finally, all bonding can be performed. Compared with the original "through hole" and "Blind hole" is more labor-intensive, so the price is also the most expensive. This process is usually only...
