E-FAST 12V 20A Lithium Battery Charger for 12V LiFePO4

The E-FAST 12V 20A Lithium Battery Charger supports 0V activation for LiFePO4 packs, ideal for golf carts RVs marine boats and trolling motors. 100–240V input.

Designed for 12V LiFePO4 packs, this charger delivers a stable 12–14.6V output and up to 20A, enabling efficient charging of high-capacity packs used in golf carts, RVs, off-grid solar setups, boats, and trolling motors. The universal 100–240V AC input supports global use, and the unit features a robust aluminum housing that helps dissipate heat during long charging sessions. With its 0V reactivation capability, it can recover deeply discharged cells so you can rely on ready-to-use batteries after storage or extended downtime. It is suitable for high-capacity deep-cycle banks (40Ah–300Ah) and ensures reliable performance across environments.

Safety is a priority with CC/CV/Float mode transitions, along with protections against over-voltage, short circuits, and overheating. The charger uses a cooling fan to maintain safe temperatures and prolong component life, while the premium aluminum housing provides rugged durability for mobile applications. The combination of precise charging (14.6V) and automatic safety cut-offs supports 12V LiFePO4 battery longevity across golf carts and marine vessels.

Quick connections simplify setup on site. The system offers dual heavy-duty connections including M8 terminals and a 50A Anderson connector for secure, fast hookups, and the dual-state LED indicators show charging status at a glance. Use cases include topping up golf cart batteries after a day on the course, maintaining RV house batteries during trips, or keeping trolling motors ready for action, without compromising battery health.
