The Baintech BT-1212-30A is a 12V 30A Marine DC-DC Battery Charger purpose-built for LiFePO4 and LiMn2O4 lithium battery systems, delivering up to 96% charging efficiency using advanced switching mode power supply technology. Charging is handled through intelligent multi-stage CC/CV control — for 12V LiFePO4 the constant-voltage threshold is 14.6V, and for 12V LiMn2O4 (3-series) it is 12.6V — ensuring your lithium bank receives a full, correct charge without the float stage that can degrade lithium cells over time.

Designed for demanding marine and off-grid environments, the BT-1212-30A carries a waterproof, dust-proof and shockproof construction that stands up to salt air, vibration and the elements aboard a boat, caravan or 4WD auxiliary system. It accepts a wide DC input range of 10–36V from a starter battery, alternator or solar regulator output, and versatile DC output terminals make it compatible with virtually any 12V battery setup. Built and certified to CE, RoHS and ISO 9001:2015 standards, this charger is a professional-grade solution for anyone running lithium batteries who needs reliable, safe and efficient charging on the water or off the grid.
