Product Details
100% Brand New and High Quality
The protection board uses a mature 4 string dedicated lithium battery protection chip, with high integration, high sensitivity characteristics, through the detection of the battery voltage, charge and discharge current and ambient temperature and other information on the battery overcharge, over discharge , Discharge over-current, short circuit, charge over-current, temperature protection and other real-time protection, but also through the external circuit to achieve the adjustment of the parameters.
