Product Description for LiTime 12V 40A DC to DC Battery Charger
LiTime 12V 40A DC-DC 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 charger, a compact, high-performance charger designed for safe and efficient charging of 12V STD, GEL, AGM, and LiFePO4 batteries using alternator or solar input in RVs, commercial vehicles, marine setups, trolling motors, boats, camping gear, off-grid cabins, and home storage setups. Featuring smart multi-stage charging (2-step CC/CV for LiFePO4; 3-stage Bulk/Absorption/Float for lead-acid) with up to 90% efficiency and 680W max alternator input, it delivers 40A output (or 20A via low current port) and fully charges a 12V 100Ah battery in just 2 hours while activating low-voltage lithium batteries. Equipped with knob for battery type selection, LED indicators for charging status, and multilevel protections against overvoltage input, output reverse connection, battery overvoltage, over temperature, short circuit, and reverse polarity, this charger ensures reliable performance. Compatible with 7V to 15.4V input, it includes M8 terminals for secure connections. Key Features:
- Multi-Stage Smart Charging: 2-step (CC/CV) for LiFePO4 or 3-stage (Bulk/Absorption/Float) for lead-acid, with knob to select battery type.
- High Efficiency & Output: Up to 90% efficiency with 40A continuous output (20A low current mode) and 680W max alternator input.
- Battery Activation: Wakes up low-voltage lithium batteries to extend service life.
- LED Status Indicators: Clear displays for charging progress and error alerts for easy monitoring.
- Multi-Level Safety Protections: Overvoltage input, output reverse connection, battery overvoltage, over temperature, short circuit, and reverse polarity.
- Versatile Connectivity: M8 terminals for secure, high-current connections to various battery setups.
- Efficient Cooling: Aluminum alloy body with heat fins for optimal heat dissipation during high-load charging.
- Universal Input: 7V to 15.4V DC input (alternator or solar) with standby self-consumption <0.6A.
