PRODUCT OVERVIEW

QS-B305ABL-50A is a lithium battery protection board specially designed for lithium phosphate,ternary lithium battery, lithium cobalt oxide and lithium manganese oxide batteries. The protectionboard consists of three, four and five series lithium battery protection boards (general version,adjust the corresponding components according to the actual demand). lt adopts mature protectioncircuit, special lC and supports disconnection protection. The imported high current and ultra-lowinternal resistance MOs (the internal resistance of a single MOS is as low as 3 milliohm) hasperfect and stable charging and discharging protection functions. The cell hardware is balancedand the balance current is appropriate, The balanced heating is reasonable and does not affectthe performance of the battery pack.

FUNCTION INTRODUCTION

1.The user can freely set 3 strings, 4 strings or 5 strings. The default delivery is the number ofstrings taken by the customer when placing the order. The customer can refer to the wiring diagramof the corresponding number of strings after receiving the goods, and there is no need to changethe board. lf you need other number of strings, you can adjust it to the required number of stringsaccording to our operation guide.

2.This protection board uses 15 high-power ultra-low internal resistance MOS transistors(8 for discharging and 7 for charging) at any cost. It supports 60A for discharging and 6OA forcharging in the same port mode and 80A for discharging and 60A for charging in the separateport mode. It is not the low power MOs in the market. The internal resistance of our single MOstransistor is up to 3 milliohm.
