My two Jersey Modeler units are a bit old, about 10 years. Has anyone upgrade to a bigger battery case? if so which one? or what site carries them and what are they called/used for? I don't mind having to transfer all my electronics over. I know many people like the convenience of just strapping the battery to the side and it looks fine, but I would like to find a bigger case for my two JM cans. rcfuelingsystems.com has bigger batteries and cases than those in my JM jugs, but I don't know if he sells those out as spare parts.
