The VEVOR 30A Smart Battery Charger is a versatile charger and maintainer designed for vehicles and small equipment. It supports 6V, 12V and 24V systems and works with a wide range of battery chemistries, including lead-acid types (Wet, Gel, MF, CA, EFB, AGM, Calcium) and 12V/24V LiFePO4 batteries. Delivering up to 30A with adjustable voltage and current, it also offers a Professional Mode to handle non-standard battery requirements. This charger includes four smart charging modes: a 7-stage Charging Mode for efficient recharging, a Maintain Mode for low-current upkeep, a Desulfation Mode to restore aged lead-acid batteries, and a Force Mode to activate batteries below 1V. Built-in protections guard against overcurrent, short circuit, reverse polarity, overheat, low temperature and overvoltage, while thermal compensation adjusts charging for safety. The 3.1 in LCD provides real-time voltage, current, battery level and status information, making it suitable for cars, motorcycles, RVs, ATVs, ride-on vehicles and compact lawn mowers.
