Overview
The Baintech BT-1224-15A is a purpose-built 12V-to-24V marine DC-DC battery charger designed specifically for LiFePO4 and LiMn2O4 lithium battery chemistries — the two most common lithium types found in marine, caravan and off-grid setups. Using advanced switching-mode power supply technology, it delivers an impressive 96% charging efficiency with intelligent CC/CV (constant current/constant voltage) staged charging, ensuring your lithium bank is brought to a full, safe charge without the cell damage caused by using a non-lithium-optimised charger.
Built for demanding environments, the BT-1224-15A features a waterproof, dustproof and shockproof enclosure that meets CE, RoHS and ISO9001-2015 standards — making it equally at home on a fishing boat, a caravan roof-box system, or a hard-working 4WD auxiliary battery setup. Diversified DC output terminals ensure compatibility with virtually any 24V battery system, while comprehensive built-in protections (over-voltage, over-temperature, over-current and short-circuit) mean you can charge with confidence even in remote locations.
- Dedicated LiFePO4 and LiMn2O4 lithium battery charging profiles via precise CC/CV control
- High 96% charging efficiency — maximises solar or alternator input energy
- Input voltage range: 10–36V DC, suits 12V starter or auxiliary battery as source
- Intelligent two-stage charging: constant current to set voltage, then current taper to 10% — no float stage that could stress lithium cells
- Rated 15A output current for efficient 24V lithium battery top-up
- Over-voltage, over-temperature, over-current (CC mode) and short-circuit protection built in
- Waterproof, dustproof and shockproof enclosure rated for marine and off-road environments
- Diversified DC output terminals compatible with a wide range of battery system configurations
- Certified to CE, RoHS and ISO9001-2015 quality standards
