5S 19V 21V 18650 Li-Ion Battery Charging Protection Board O

Detailed Information About The Product:

1. Made of high-quality materials with stable performance, this protective plate is suitable for 5S lithium-ion batteries and is mainly used for electric tools.
2. This product uses 5 series of lithium battery management dedicated ICs as processors to detect real-time information such as voltage, charging and discharging current, and environmental temperature of each battery.
3. Welding wires are convenient for connection, and selecting the correct protective plate is crucial for extending the battery life.
4. Stable various charging and discharging protection functions, achieving protection functions for battery overcharging, discharging overcurrent, short circuit, charging overcurrent, temperature protection, etc
5. The protection board has delayed self recovery, low power consumption, and can be used for the Makita battery pack. With thick copper hardware terminals, durable! Long term use does not generate heat.
