Hello all. I am a new owner of a 21" hybrid trailer, a 2015 flagstaff shamrock. My wife and I want to do a little camping and traveling for the first time in our lives. My trailer currently has 2 interstate wet cell batteries that are in need of replacement. I have a 3800 watt Wen generator that I bought for the trailer as well. I am considering purchasing a Battle born 100ah lithium battery, mainly for the increased ah capacity, but also because I want less maintenance. I do not currently plan to install any solar as we don't do much boondocking, although we do go to "harvest host" sites at times where there is not power hookups. Does this plan make sense, as far as using lithium batteries without solar, and charging it with my generator or when plugged in to power. Is it reasonable to expect that between trips the lithium battery will hold charge for a month or two at a time with no problems?
