If you're trying to choose the best deep cycle battery for your 4WD's dual battery setup, watch this! Lithium batteries may have a higher price tag but they've got a much longer lifespan, and a lot of pros: - Twice as many usable amp hours (AH) as AGM batteries - Higher lithium input charge means you can charge your battery faster with a DCDC charger - Higher lithium discharge rate means you can run high amp draw things like 240v inverters, power tools and blenders off your 12v system! - More discharge cycles so your battery lives a much longer life - Good quality lithium batteries have a built in BMS (battery management system) More on Shauno's choice:
