I haven't done any off grid camping yet but just testing the battery
in my driveway the battery
hardly lasted at all running almost nothing. Few hours of leaving my fantastic fan on would just about drain it. So I wanted to do some good testing and got a 180 watt portable Zamp solar panel
. I charged the battery
100% (12.71V) and disconnected the battery. The battery was at 12.6 the following day, a week later and it is at 12.43V. It has not been connected to anything since it was charged. I contacted the manufacturer of the battery (Centennial Deep Cycle DC24RVM non sealed Lead Acid) and it turns out this battery is 75ah. Kind of lame for a 21' Bigfoot
. Not sure if that is how it was sold
, and the first owners just ran on the grid, or if the first owners of the trailer had better batteries and used them in their new trailer so they threw this one in.
So now I need to decide if I'm going to upgrade to a set of sealed deep cycle AGM batteries, or just go full on with a lithium conversion like Jon Vermilye did here:
I'm kind of a gadget geek so having lithium seems pretty neat, but I'm still not 100% convinced I'm going to keep the trailer. I love it but it seems just a bit too big. Towing it with my Colorado is ok but not super fantastic. Really I'm still getting use to towing so with some more practice I may find it's ok. Adding 2 decent AGM batteries is going to add a lot more weight
than the lithiums, and I guess if I do end up selling it, having upgraded the batteries wouldn't be a loss since I could add it into the cost of the trailer right? Either way I go, I am pretty sure there is enough room for the batteries. There is a large area in the front under the cowl behind the propane
tanks. 2 batteries should fit great there.
Mostly maybe I'm just venting I guess, much like my poor little 75ah lead acid battery.
