I am making a trailer out of a Land Rover Freelander. (Its ok to laugh) I have chopped it at the A pillar and want to put most of the weight over the rear axle. That being said there is a small storage compartment in the cargo area that is deep enough for motorcycle battery on its side but not car batteries. My though is to put 2 odyssey sealed batteries in the compartment. My only uses at the moment where I will use the batteries are in camp where they will charge the cell phones and power the LED lights I am installing. While driving I will be charging them through the 7 pin trailer connector. Any an all input is welcomed.
