This is the 1V variant of the 3 Series 20A 18650 Lithium Battery Protection Board 11.1V 12V 12.6V in Battery Protection Board. Available at ₹37.29 (₹31.60 + GST) with free shipping across India.
The 3 Series 20A 18650 Lithium Battery Protection Board with Balance is designed for 11.1V, 12V, and 12.6V lithium battery packs, making it ideal for use in applications such as electric drills, sprayers, LED lights, and low-power inverters. Key features include:
Automatic Recovery Function: Restores the board after a short circuit or overcharge, ensuring reliable operation.
Low-Resistance MOSFETs: Equipped with 10 low-resistance MOSFETs to reduce heat generation and improve overall efficiency.
High Discharge Capacity: Supports continuous discharge up to 20A and a balanced current of 100mA, ideal for high-power applications. (Note: Reduce the load current if the cooling environment is inadequate.)
Wide Compatibility: Compatible with 3.6V or 3.7V nominal voltage lithium batteries, including 18650, 26650, and polymer cells. The board supports a charging voltage range from 16.8V to 18.1V.
High Charge Current Limit: Allows for a continuous charge current of 20A, making it suitable for drills with a starting current below 80A and power requirements under 135W (with balancing).
Compact Design: The board measures approximately 46 x 60 x 3.4 mm, making it easy to install in small spaces or directly on battery packs.
This protection board offers both efficiency and safety, ensuring balanced charging and discharging for longer battery life and optimal performance in demanding applications.
3 Series 20A 18650 Lithium Battery Protection Board 11.1V 12V 12.6V
Features:
- 3S 11.1V 12.6V 20A 18650 lithium battery protection board (comes with recovery function-AUTO Recovery).
- Application: Nominal voltage of 3.6V, 3.7V lithium battery (including 18650.26650, a polymer lithium battery).
- Continuous discharge current (upper limit): 20A (if the cooling environment is not good, please reduce the load current use).
- Continuous charge current (upper limit): 20A.
- Suitable for the drills with starting current below 80A, power 135W below.
Note:
- The Successful start of the drill requires a three 15C-20C power battery, or six 10C-15C power battery (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.
- 4 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. The Discharge test, the voltage drops faster battery that group is a poor battery.
