This lithium-battery protection circuit suits both liquid/polymer lithium-ion and 4S LiFePO4/Li-ion batteries. It offers multi-protection functions for safe, stable operation, with customizable working current (4-40A).
Features
High - quality Appearance and Craftsmanship: With a rational wiring layout and neat component arrangement, there is no oxidation or stains. The soldering is excellent, and the PCB board is made of fiberglass double - sided material with eco - friendly lead - free solder.
Precise Electrical Performance: It has specific over - charge and over - discharge detection voltage ranges for different batteries. It can handle 40A charge and discharge currents stably, with fast - responding protection functions and low self - consumption.
Multiple Protection Functions: It provides over - charge, over - discharge, over - current, short - circuit, and temperature protection. The circuit can automatically recover after protection by removing the load.
Application
This protection circuit is suitable for 4 - series lithium - ion rechargeable battery packs and is widely used in various devices like portable power tools, energy storage systems, and electric vehicles to ensure the safety and performance of battery packs.
