The 24-085-21-1754-B-Group Battery, a BCI Group 24 lithium iron phosphate (LiFePO4) design, is engineered for deep-cycle applications demanding high reliability and extended lifespan. With 48V/25Ah capacity, 50A BMS, and 2560W load capability, it excels in off-grid energy storage, marine propulsion, and mobile power systems requiring robust cycling performance (15,000 cycles) and 10-year operational durability.
What distinguishes BCI Group 24 lithium batteries in mobile applications?
BCI Group 24’s standardized dimensions and LiFePO4 chemistry enable seamless integration into RV/trailer battery compartments while delivering 10-15% higher energy density than AGM equivalents. Their 100% depth-of-cycle capability supports uninterrupted power for refrigeration, lighting, and HVAC systems during extended off-grid use.

These batteries feature low self-discharge rates (3% monthly) and operate across -20°C to 60°C, critical for marine and overlanding scenarios. Pro Tip: Use a compatible 48V LiFePO4 charger with temperature compensation—charging below 0°C without heating elements accelerates lithium plating. For example, a dual-battery Group 24 setup in campers can power 2kW loads for 4-5 hours, outperforming lead-acid systems by 300% in usable capacity.

How do these batteries enhance solar energy systems?
With 51.2V nominal voltage aligning with solar charge controllers, Group 24 LiFePO4 units minimize DC-DC conversion losses. Their 25Ah capacity at 1C discharge sustains 2.5kW solar arrays, storing 1.28kWh usable energy—sufficient for overnight power in small off-grid cabins.
Advanced cycle life (15,000 cycles at 80% DoD) reduces replacement frequency versus lead-acid alternatives. Practically speaking, a 4-battery bank provides 5.12kWh storage, enabling 24/7 operation of 500W critical loads. Pro Tip: Implement active cell balancing every 50 cycles to maintain <2mV cell variance, crucial for maximizing solar storage efficiency.
| Parameter | Group 24 LiFePO4 | AGM Equivalent |
|---|---|---|
| Cycle Life (80% DoD) | 15,000 | 500-1,200 |
| Weight (kg) | 14.5 | 25-28 |
| Charge Efficiency | 98% | 85% |
Are marine applications viable for this battery type?
IP67-rated Group 24 lithium batteries resist saltwater corrosion and handle vessel vibrations up to 5G, making them ideal for trolling motors and navigation systems. Their 50A continuous discharge supports 12V/24V marine converters, powering 2kW sonar/GPS arrays without voltage sag.
During testing, these batteries maintained 95% capacity after 1,000 salt spray hours (ASTM B117 standard). For example, twin 48V Group 24 batteries in a 28-foot sailboat reliably power 1.5kW bow thrusters for 45-minute maneuvers. Pro Tip: Install battery trays with 15mm ventilation gaps—LiFePO4’s low gas emission permits safer below-deck mounting versus vented lead-acid.

FAQs
Yes, when paired with pure sine wave inverters, it reliably operates CPAP machines and portable dialysis units—its <2% voltage ripple meets IEC 60601-1 medical power standards.
Is paralleling multiple Group 24 batteries safe?
Only with factory-matched units having <0.1V open-circuit variance. Random paralleling risks creating reverse-current pathways that degrade cells unevenly.
