RV, Van & Overland

Check your RV's converter/charger, solar charge controller, alternator charging system, battery monitor, and other charging equipment to verify they support LiFePO4 batteries. You should also confirm that the wiring, fusing, and other components are appropriately sized for the lithium battery system.

Your required amp-hour capacity depends on the appliances and electronics you use, how long you use them, and how frequently you can recharge the battery. Calculate your daily energy consumption and select enough battery capacity to meet your expected needs while allowing an appropriate reserve.

Yes, Dakota Lithium batteries can be charged from an RV alternator, but most deep-cycle lithium house batteries should be charged through a LiFePO4-compatible DC-DC charger rather than connecting the battery directly to the alternator. Dakota Lithium recommends a DC-DC charger for RV applications because it regulates the charging current, provides the appropriate lithium charging profile, and helps protect both the battery and the vehicle's alternator.

A DC-DC charger is especially important for larger RV house banks because lithium batteries can accept charge much faster than lead-acid batteries, which can place significant demand on the alternator.

Note: Certain DL+ Dual Purpose batteries are specifically designed for automotive or marine starting applications and may be capable of direct alternator charging when the alternator's output is compatible with the battery's charging specifications. Always check the specifications for your specific battery before connecting it directly to an alternator.

Before storing your RV, make sure your Dakota Lithium batteries are at the recommended state of charge and disconnect any unnecessary loads that could slowly drain the batteries. If the RV will remain plugged into shore power, verify that the RV's converter/charger is compatible with LiFePO4 batteries. For extended storage, follow the specific storage and temperature recommendations for your battery model.

Whether you can run an RV air conditioner from your battery system depends on the air conditioner's power requirements, inverter size, battery-bank capacity, and the battery bank's maximum discharge capability. High-demand appliances may require multiple batteries and a properly sized inverter.
