<div dir="ltr" style="">Hank, I have been doing a lot of research on this vary issue with my new boat, the R800. I really like the Valence U27-12xp lithium <span><span style="color:rgb(0, 0, 0);font-family:times new roman, new york, times, serif;font-size:16px;">Li FePO4 </span></span>battery. There is a least one commercial private sub that uses these battery modules. Do a search on YouTube for info/ teardowns on these batteries. What is good about them is battery chemistry is more stable than conventional LI batteries and heavy duty electronics. Not your typical crappy Chinese electronics. They come in a group 27 form factor with a nominal 12V with a built in BMS in each module. Each module has a 137AH capacity.<br clear="none"></div><div dir="ltr" style="">These modules new are on the order of $2,500 each but are readily available on Ebay at $450 each. Each module has a life of 3000-4000 cycles with used modules on Ebay with 10-300 cycles so lots of life left in them. They are set up so that an overall BMS unit manages the entire pack interfacing with each modules interval BMS. These modules can be configured in just about any series/parallel arrangement you can think. For my boat, I am looking at 3S2P configuration, that is, 3 of these U27-12XP's in series with 2 banks, one in each pod in parallel. This would give a bank voltage of 36V and a bank capacity of 274AH or 9.9kWh. I am using 36V the main propulsion bank to mate with the Minn Kota 101 running at 36V nominal. IF you want more capacity, you would put more more in parallel, i.e., 3SnP where n=1, 2... I am also using these for the emergecy battery bank with a 0S2P configuration for 24V nominal.</div><div dir="ltr" style="font-family:times new roman, new york, times, serif;font-size:16px;"><br clear="none"></div><div dir="ltr" style="font-family:times new roman, new york, times, serif;font-size:16px;">Communication with module and cells within each module is via. serial communication using RS-485.
