B2B 12V deep-cycle range
12V LiFePO4 batteries for lead-acid replacement projects.
12V remains a practical platform for RV house power, compact solar systems, service power and compatible marine auxiliary applications. Choose capacity from the energy budget and current from the actual loads.
Which 12V LiFePO4 battery should a B2B buyer start with?
Start with a load and charging brief. A 12.8V 100Ah reference battery stores 1.28kWh and is suited to compact auxiliary systems where the maximum continuous load is within its 100A limit. A 12.8V 300Ah reference battery stores 3.84kWh and supports up to 150A continuous discharge, but its larger capacity does not make it an unrestricted high-power inverter battery.
What to confirm before quoting
- Expected daily energy use in Wh and desired autonomy.
- Continuous and surge DC current at the battery, especially for inverter loads.
- Solar, alternator/DC-DC and mains charging equipment.
- Temperature range, physical space, terminal access and approved expansion plan.
