This is the one I bought $1,057.48 shipped. The big name companies like ABYSS, Dakota, Battle born or Iconic are way more expensive than this for less features and a lesser build. This is a Roy Pow product. I like the fact that it is 1 battery, 24V100AH. I have done a lot of research. Could I have gone cheaper, yes, but I don't plan on replacing this for a very long time, if ever. Haven't had a chance to get it in the boat yet. Waiting for spring!
