I own a 24 volt gel cell beside the fact that they are a little expensive. I feel it is money well spent if you use a electric motor alot. I have a 74 volt minkota Tide Water and I can run it hard all day and it still has plenty of juice left at the end of the day. There is no fumes and very compact for a 24 volt system. They do charge quick and hold a charge for a long time even if you don't use it right away. I feel it is a good investment if you have the money to spend. That's just my opinion though.
