Features 1、Stable Working: Nano amorphous isolated fully symmetrical transformer, ensuring minimum pressure difference. Ultra low internal resistance MOS devices form an ultra low dynamic impedance inverter circuit, achieving high power balancing operation. 2、Auto Balancing: Intelligent MCU chip master management, which can achieve automatic and autonomous balancing work. Automatically detect the minimum voltage of the battery, stop working when the battery has low energy, and protecting the battery from power loss. 3、High in Safety: Equipped with overcurrent protection resistors at each input end of the string, ensuring safety. Also equipped with automatic voltage detection and analysis function, it is convenient to understand the battery balance situation. 4、Premium Design: Equipped with LED high definition digital display screen for clearer data observation. Design of inverter heat dissipation under extreme balance of high voltage difference. 5、Good Protection: Add a small short circuit breaker device for over temperature and over current protection, which can control the sudden abnormal excessive current, break the circuit at over temperature, and protecting the battery pack from normal and continuous balance.
