[PSUBS-MAILIST] Batteries

[Brian V Ryder via Personal_Submersibles]

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
