RV Battery

Your RV battery is the difference between actually camping and parking. We stock lithium RV batteries in the 12V house-bank sizes that RVs, campers and van builds actually use! From 100Ah weekenders to 400Ah off-grid banks for serious power. LBZ has the deep cycle RV battery power that charges faster, weighs less than half of lead-acid, and lives through thousands of nights for even the most active RV’ers.

Deep Cycle RV Batteries, Without the Lead

A deep cycle RV battery in lithium runs the same furnace, fridge and lights as your old lead-acid bank while using far more of its rated capacity: LiFePO4 discharges to 80 to 100 percent without damage, where flooded batteries want to stop near half. That means a 100Ah lithium battery replaces most 200Ah lead-acid setups, sheds well over a hundred pounds from your rig, and recharges in a fraction of the time from shore power, alternator or solar. No watering, no terminal corrosion, no off-season babysitting: store it charged and it loses only a few percent a month.

RV Battery FAQ

What size lithium battery does my RV need?+

The industry-standard house battery is a 12V 100Ah, which covers lights, fans, water pump and a fridge for a weekend. Boondockers and four-season rigs typically step to 200 to 400Ah banks. Call us at 888-274-7544 and we will size your actual loads in a few minutes.

Can I charge a lithium RV battery from my converter?+

Only if your converter has a lithium charge profile. Older lead-acid converters undercharge LiFePO4 and leave capacity on the table; a lithium-profile converter or DC-DC charger gets you the full bank and the full lifespan.

Do lithium RV batteries work in winter?+

Discharging works fine well below freezing, but standard LiFePO4 blocks charging under 32 F to protect the cells. For four-season camping, choose a heated pack: it warms its own cells and charges through winter without you thinking about it.
