Note: The Successful start of the drill requires three 15C-20C power battery, or six 10C-15C power batteries (ordinary 18650 cannot start the drill!!). Strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, 16.8V, do not deliberately short circuit. When the load of the brush motor is used, try to connect a non-polar capacitor (withstand voltage above25V, 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 it in series. In the Discharge test, the voltage drops faster battery that group is a poor battery. Package Includes: 1 x Battery Balance Module Enhanced 18650( 3S, 60A )

[Lithium Battery Protection Board] This is 3S 12V 25A 18650 Lithium Battery Protection Board 11.1V 12.6V High Current With Balanced Circuit Over Charge Over-Discharge Over Current And Short Circuit Protection Function. Board charging and discharging are the same port, the board includes the balanced circuit. When the charge balance, the board will be a bit warm, even after disconnecting the charger, some are still in the balance, will continue to warm for a while until below the equilibrium break threshold. The protection board cannot be used for iron lithium polymer battery (for other batteries, no matter what material, as long as the overvoltage and put voltage can be used for cutting), electric finish machinery, electric bicycle batteries, car, and motorcycle starter battery protection. Applicable to the following products (within rated power): Electric drill, 775 motors (6A-10A), small power inverter, small power vacuum massager battery, LED lamp, 12V standby power electronic products, 12V120W car washing pump, battery, solar street lamp monitoring standby power supply, and other products. Rated current can’t over 25A, it can’t exceed 50A per 0.5 seconds. Specifications : Overcharge voltage range: 4.25-4.35v + 0.05v. Overdischarge voltage range: 2.3-2.7v + 0.05v. Operating current: 0 – 25A. Operating temperature: -40 – +50℃. Instantaneous current: 35 – 40A. Storage condition: -40 – +80℃. Quiescent current: less than 30uA. Balance current: about 40 – 50mA. Effective life: more than 30000 hours. Internal resistance: less than 100m ohm. Short-circuit protection: protection, delayed self recovery.
