Choosing the right battery voltage is one of the most important decisions for any RV or camper owner. Both 12V and 24V deep-cycle lithium systems have their place — here is how to decide.
12V: the common RV system voltage
Most RVs are wired for 12V, so a 12V 100Ah LiFePO4 battery can retain the system voltage. Compatibility still depends on the charger, alternator or DC-DC charger, inverter settings, cable size, protection and physical installation.
24V: for bigger loads and longer runs
If you run larger inverters, air conditioners or higher-power appliances, 24V halves the current, reducing cable size and losses. It is also the natural choice for custom builds and electric trolling motors.
Both share the same core benefits
Whatever voltage you choose, compare rated energy, BMS current, charger settings, cycle-life test conditions and installation dimensions. LINEX offers 12V and 24V deep-cycle models from 10Ah to 300Ah. Use the published specifications and measured load to select capacity.
