Are you looking for a lithium battery upgrade for your RV? Vatrer could easily be what you're looking for. This 300 amp hour lithium battery has reshaped the way we can camp now and has inspired us to change our approach. We were contacted by a company called Vatrer who is apparently becoming a leader in the lithium battery world and their options seem to be limitless. Vatrer has batteries ranging from 100 amp hours to over 400 amp hours with options including internal heating features, abilities to arrange multiple batteries in series, low voltage cut off, low temperature cut off, and dozens more features. Vatrer supplies lithium battery upgrades for golf carts, boats, home energy systems but this video will focus on RV lithium battery upgrade because we don't have a boat or a golf cart... Vatrer supplied us with a 300 amp hour lithium battery to replace our old 35 amp hour lead acid battery that originally came with our camper back in 2017.
