Description:
Application: lithium iron phosphate, ternary lithium battery, lithium cobalt oxide, lithium manganese oxide battery pack
QS-B305ABL-50A is a lithium battery protection board specially designed for lithium phosphate, ternary lithium battery, lithium cobalt oxide and lithium manganate battery. This protection board consists of 3 strings, 4 strings, 5 series lithium battery protection board (the universal version adjusts the corresponding components according to actual needs), adopts mature protection circuit, special IC and supports disconnection protection, and imports high current ultra low internal resistance MOS ( The internal resistance of a single MOS is as low as 3 milliohms. It has perfect and stable charging and discharging protection functions. The battery core is balanced, the balance current is proper, the balanced heat is reasonable, and the performance of the battery pack is not affected.
