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)
