Electrobot BMS 3S 40A Li-ion Lithium Battery Charger PCB BMS Protection Board Electronic Components Electronic Hobby Kit

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!!!).// Features: Internal resistance: Less than 100m? Working temperature:-40° ~ +50°Celsius Storage Temperature:-40° ~ +80°Celsius Weight: 9.8g Size:41 mm×60 mm×3.4mm/1.61? ×2.36?×0.13?// Note: Strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, do not deliberately short circuit. When the load of the brush motor is used, try to connect a non-polar capacitor (withstand voltage above 25V, capacity 10uF-100uF) to the motor's positive and negative terminals to prevent the reverse spike from the motor. Break the MOS tube. 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 The Discharge test, the voltage drop faster battery that group is poor battery. Do not mix the good battery and poor battery to use. The internal resistance of 3 battery capacity are closer will be better.// Package Includes: 1x BMS 3S 40A Li-ion Lithium Battery Charger PCB BMS Protection Board.
