Which Would Last Longer 200 ah Lithium or 330 ah AGM Battery
Question:
Hi, I am wanting to upgrade the battery on my travel trailer. I am looking at the Brightway 330ah AGM vs the 200ah Lithium. Currently, with a single group 27 battery that came with the trailer, we have about 4 hours of use....which is primarily simply used running the fan for heat as well as the fridge. I know that the Lithium has a greater discharge depth, but how would the 330ah AGM compare to the 200 ah Lithium in terms of usage time between charges? Thanks

Expert Reply:
AGM batteries are only recommended to be discharged up to 50 percent whereas Lithium batters are not affected by depth of discharge which means you can totally discharge the battery and you'd be totally fine. So essentially a 200 ah Lithium battery is as useful as a 400 ah AGM which means for your comparison the 200 ah Lithium would last longer than a 330 ah AGM.
For a 200 ah Lithium we have the part # PS64FR.
