The battery in that system is a Lithionics the (Li3) is the giveaway. Best to look into the marine version called the OPE-Li3 a partnership between Ocean Planet Energy (Bruce Schwab) and Lithionics.. In my opinion it is the best and safest LFP house bank being built right now. The marine version is extremely well executed & designed. With LiFePO4 you definitely don't want to cut corners..
