A freind of mine is upgrading from 12v to a 24v system on his bass boat. He is going to locate the two batteries under the front deck somewhere. He asked me if I had seen any ready made, drop in comparments for sale anywhere. I told him no, but I never looked for one. Seems like somthing that should be out there, but I haven't been able to find any. Can anyone suggest a source for this product?
