Hi Brian,I am curious why you would want Lithium batteries instead of AGM.  Is it a weight issue?  In the DW it makes sense because weight is a huge factor, I would have guessed with your sub volume it would not be an issue.  Hank

Would be interested in anything you turn up as I am looking at either Lithium Ironor Lithium Sulphur if it eventuates. I have a year or so to make up my mind though.Hugh has had some experience (bad) with Lithium Sulphur. He may give some adviceif you take that path.Cheers Alan

Hello it's been a long time since I have chimed in but I have a few questions for the group 
I am getting ready to move and completely overhaul DSH 2 our pierce built sub and the final boat will resemble antipodes without the rear viewport 
My question is batteries I will have funding available for lithium polymer battery's has anyone used them or any knowledge on them 
And also are there any drawings around of antipodes ? 
Any help would greatly be appreciated and the boat will be at our shop in Salem Ohio if anyone wants to come by and lend some much needed knowledge 

Thanks Brian
