This protection board adopts mature protection circuit, special IC, imported high current ultra low internal resistance MOS (single MOS internal resistance as low as 3mΩ), and has perfect and stable charging and discharging protection functions. Small volume and large current can be used in high current applications such as power tools and aircraft models. Before installing the protection board, the battery must be matched well (the voltage difference between each battery is not higher than 0.05V, the internal resistance is not more than 5mΩ, the difference of the capacitance is less than 30mAh), the better the battery consistency, the longer the battery life, and the best performance of the protection board. This protective plate cannot be used for lithium iron phosphate batteries. Lithium battery protection board is strictly prohibited to be used in series.
