Product Description for LiTime 12V 40A DC to DC Battery Charger with MPPT
LiTime 12V 40A DC-DC MPPT LiFePO4 Smart Lithium Battery Charger – Efficient Alternator & Solar Charging Solution for RV, Marine, Trolling Motors, Boats, Camping, and Off-Grid Systems
Elevate your battery charging with the LiTime 12V 40A DC-DC MPPT charger, a compact, high-performance charger designed for safe and efficient charging of 12V LiFePO4, Gel, AGM, Calcium, and SLA batteries using alternator, solar panels, or starting battery power in RVs, trolling motors, boats, camping gear, off-grid cabins, and home storage setups. Featuring MPPT technology for up to 93% efficiency, it delivers 40A output and up to 600W input, fully charging a 12V 100Ah battery in just 2.5 hours while activating dead lithium batteries at low voltage. Equipped with LED indicators and operation buttons for easy mode switching (alternator, solar, or reverse charge), plus multilevel protections against overvoltage input, output reverse connection, battery overvoltage, over temperature, charging timeout, and BMS protection for LFP batteries, this charger ensures reliable performance. Compatible with 7V to 15.4V input, it includes ACC wire, solar input terminal, DC input terminal, and output terminal for secure connections. Key Features:
- DC-DC MPPT Technology: Maximizes alternator and solar input efficiency up to 93%, with 600W max input for faster charging.
- Multi-Mode Operation: Alternator mode, solar mode, and reverse charge (when service battery >12.5V and starting <12V); easy switching with LED indicators.
- Battery Activation & Compatibility: Activates low-voltage lithium batteries; supports LiFePO4, Gel, AGM, Calcium, SLA with 100% charge capability.
- Multi-Level Safety Protections: Overvoltage input, output reverse connection, battery overvoltage, over temperature, charging timeout, and BMS protection for LFP.
- Versatile Connectivity: ACC wire, solar input terminal, DC input terminal, and output terminal for flexible installations.
- Efficient Cooling: Built-in fan for heat dissipation during high-load charging.
- Universal Input: 7V to 15.4V DC input (alternator or solar) with max 600W power; standby self-consumption <10mA.
- Compact & Durable: Humidity 0-90%; operating temperature -14°F to 113°F (-10°C to 45°C).
