BMS 3S 40A 18650 BOARD PENGISI DAYA BATERAY LITHIUM

BMS 3S 40A 12.6V Protection Board Enhanced Version 18650 Li-ion Lithium Battery Package: 1 x Module BMS 3S 40A 12.6V Protection Board Specifications: - Charging voltage:12.6v ~ 13.6v - Over Charge voltage:4.25±0.05v - Over Discharge voltage: 2.5v±0.05v - Continuous discharge current (upper limit): 40A (if the cooling environment is not good, please reduce the load current ) - Continuous charge current (upper limit): 20A - Internal resistance: Less than 100mΩ - Working temperature:-40 ~ +50Celsius - Storage Temperature:-40 ~ +80Celsius - Weight: 8.8g - Size:41 mm×55 mm×3.4mm/ 1.61″ ×2.17″×0.13″ Suitable for: 1.Suitable for lithium batteries with nominal voltage of 3.7V and full voltage of 4.2V (including 18650, 26650, polymer lithium batteries) 2.Suitable for electric drill with starting current below 80A and power below 130W . Attention: * To successful starting the drill requires three 15C-20C power batteries, or six 10C-15C power batteries (ordinary 18650 battery can not start the drill!! Recommended power battery models: SONY VTC4, VTC4A, VTC5A, VTC6). * 0V and 12.6V cable, use copper wire of more than 3 square millimeters (cannot use nickel plate!!!). Strictly according to the diagram wiring: 0V/4.2V/8.4V/12.6V,Otherwise it will cause damage to the chip. * 3 groups of batteries in series, please ensure that the voltage of each group of batteries,if not the same, please fill each battery separately and then use in series. * The Discharge test, the voltage drop faster battery that group is poor battery.
