Lithium Battery Charger Protection Module (BMS) 7S 15A 24V

From the shop's description

Discharge products with above 3A current, battery discharge rate should be more than 3C. Magnification calculation formula: 1C rate battery,2000 capacity equals 2AH x 1=2A working current;3C rate battery,2000 capacity equals 2AH x 3=6A working current. Short circuit protection, delay self-recovery, provides overcurrent, overcharge and over discharge protection. Applications: Massager battery pack LED light backup power supply 12V electronic products Solar street light battery pack Monitoring standby power supply,etc. Specification: 7 Series (7 batteries in series) 25.2V (rated voltage of 3.6V polymer battery) 25.9V (rated voltage of 18650 or 3.7V lithium battery) 29.4V (voltage after the lithium battery is fully charged) Upper limit working current: 15A Upper limit instantaneous current: 20A Overcharge voltage range: 4.25 +/- 0.05V Over-discharge voltage range: 2.5 +/- 0.05V Charging voltage: 29.4V Quiescent current: less than 30uA General Specification Material: Plastic + Metal Model: HX-7S-TY-T20 Color: Green Size: 6x4x0.6cm (LxWxH) Weight: 30 g Note: CAN NOT be used for lithium iron phosphate battery, xenon lamp, and drill battery pack, electric fish battery pack, electric bicycle battery pack, baby car battery, 550 or more power type motor,1W fish eye LED light.
