Equalizer is used for 12V batteries connected in series to maintain voltage balance. This battery equalizer ensures charge and discharge balance among series-connected batteries. It provides bidirectional compensation. With reverse polarity protection and low-voltage disconnect, it extends battery life. It can remain connected to the battery pack continuously to automatically maintain state-of-charge balance. The intelligent battery voltage balancing system helps maintain battery health and prolongs lifespan. Maximum equalizing current is 4A, with fast and intelligent balancing speed. It protects individual batteries, extends battery pack service life, and improves runtime. When voltage differences are large, the equalizer automatically reduces equalizing current and pulse duty cycle for improved efficiency and intelligence. Built-in MCU chip enables integrated multi-protection management, accurate data acquisition, and fast processing. Reverse connection protection safeguards both the equalizer and batteries from damage due to incorrect polarity connections. Compatible with various battery chemistries, including lead-acid, gel, lithium iron phosphate (LiFePO4), and ternary lithium. Features solid heat dissipation via aluminum housing and thermal conductive adhesive for enhanced cooling performance. Battery standard voltage: 24V. Compensation current: 0–4A. Standby current:
