Description
The protection board can be used on a four-component polymer lithium battery pack with nominal voltage of 14.4V, 14.8V, 16.8V or a four series 8650 lithium battery pack.
Above configuration allows for overcharge and over-discharge, short circuit protection. There is no high instantaneous current to activate the function in the power supply application, and erroneous trigger protection is avoided in the inverter application, so it is more convenient to use.
Note: There is no part design on the back and can be connected to the heat sink to ensure long-term high current operation.
