12V Batteries

About

12V LiFePO4 Batteries for Every Off Grid and Mobile Power Application The 12V battery is the most universally used voltage in portable and mobile power. It is native to RVs, boats, vans, and trucks, compatible with the widest range of inverters and charge controllers on the market, and the natural starting point for most people building their first solar or off grid system. At Off-Grid Source, we carry a broad selection of 12V LiFePO4 batteries across the full capacity spectrum, from compact units for small electronics and trolling motors to high capacity deep cycle banks for serious off grid builds, all with the LiFePO4 chemistry that makes them a lasting upgrade over lead acid. Why 12V LiFePO4 Is the Right Upgrade Lead acid has been the default for 12V systems for decades, but the case for switching to a 12V LiFePO4 battery is straightforward once you look at the numbers: Dramatically longer cycle life. Most LiFePO4 batteries in our 12V collection are rated for 3,500 to 8,000 plus cycles at 80% depth of discharge. Lead acid typically delivers 300 to 500. That difference represents years of additional service life from a single purchase. More usable capacity. Lead acid is generally limited to 50% depth of discharge to preserve longevity. LiFePO4 delivers 80 to 100% usable capacity, effectively doubling the energy you can draw from the same rated amp hours. Stable voltage under load. The flat discharge curve of LiFePO4 means your inverter, trolling motor, and electronics run at consistent power right through the discharge cycle rather than experiencing the gradual voltage sag common with lead acid. Significantly lighter. A 12V 100Ah LiFePO4 battery typically weighs 25 to 30 pounds compared to 60 to 70 pounds for an equivalent AGM unit. That difference matters enormously in a boat, van, or RV where weight affects range and handling. Zero maintenance. No water top-offs, no equalization charges, no terminal corrosion to manage. Install it and run it. Features Worth Pri
