4S Smart BMS 12V Lifepo4 Battery Protection Board Continuous 200A with Balanced UART Communication

4S Smart BMS 12V Lifepo4 Battery Protection Board Continuous 200A with Balanced UART Communication

Features:
- Support UART communication
- Intelligent battery balancer: Continuous charge and discharge currents are 200A. 150mA high current balancing
- Multiple protections: Overcharge, over-discharge, over-current, short-circuit, temperature-controlled and balanced protection
- High-current copper strip makes the diversion more stable
- Thickened copper strip is used for diversion. Continuous charge and discharge currents up to 200A. Copper bar is about 2mm/0.08" in thickness
- Board size: 192 x 105 x 20mm/7.6 x 4.1 x 0.8"
- Using front-end acquisition chip and MCU
- Phone APP: Battery parameters can be modified. Read the detailed parameters of battery through the APP. And the parameters can be customized and modified (*The software interface is optimized, and there may be differences in the interface, but it does not affect the use of functions*)
- Host computer monitors the state of battery use: Monitor the voltage of each battery, total voltage, average voltage, high and low voltage difference, remaining capacity, etc.
- Stable operation: Set up an independent watchdog for real-time detection procedures plus secondary protection
- Temperature-controlled detection: Built-in balanced 2-channel temperature monitoring
- APP and upper computer: It can lock battery and battery cannot be discharged. It supports Chinese and English interfaces
- Double detection makes it safer to use: AOI optical inspection equipment is used to inspect appearance, missing welds and false welding of the product. Professional testing machine enables fully automatic function detection of the protection board
