I have yet to find out Hippocampus, how the insurance market views the big power batteries. Its a next year before launch task, my lack of experience on a 24m hull might be a bigger issue! The ones we have installed from Praxis have marine approval (DNV) and isolation in their own containment with its own exhaust, cooling and alarm system so we have a degree of protection in case of runaway. We have also split the bank in to two times 60kWh for the same reason. If the vessel was within Class it would require complete battery room isolation which is near impossible on a huller size <24M. I would be very nervous of just creating big LiPO banks from multiple modular units without consideration of runaway and its effects. House batteries (20kWH MG Systems) are also isolated for the same reason.
