Your recreational vehicle needs a reliable and robust battery that won’t fail during critical times. After all, the last thing you want to happen is for your RV to break down in the middle of nowhere because of a low-quality or inefficient power source. Moreover, you wouldn’t want your appliances to stop running because the deep cycle battery ran out of juice. In that case, you might want to invest in a good RV lithium battery system. Here’s a guide to help you pick the right battery for your RV, van, or camper:
Know the batteries required
RVs typically require two types of batteries: the starter battery for the engine and the deep cycle battery for powering appliances and electronics. If you have solar panels, these can recharge the lithium deep cycle RV battery and they won’t directly power the electronics or appliances. Deep cycle batteries are also called ‘house batteries’ and they are your power source for running the lights, fridge, and other essential items in your vehicle.
Most electronics in recreational vehicles and vans can work with any 12-volt RV lithium battery system. If you want a reliable battery with the longest lifespan and runtime while ensuring compatibility with your solar panels, consider lithium iron phosphate (LiFePO4).
Know the right size for your RV
Consider the size of your vehicle, the types of appliances and electronics you’re likely to use, and how long you will use them so you can pick the right sized lithium deep cycle RV battery. Pay close attention to appliances that draw a lot of amps or power, such as air-conditioning, as they may require a larger battery bank. You should also consider the size of your solar panels if you have any.
Choose an RV lithium battery system that has a built-in LED charge indicator to help you easily identify how much charge is left. Look for a built-in battery management system, too. It’s an electronic board that controls the battery and protects it from reverse polarity, short-circuiting, and overcharging.
