Looking at upgrading my boat liveing battery setup. Am following this guide to dip my toe in, currently my main 500amp leadacide battery bank has failed after 4 years use due to a fault on my #MPPT solar controller with the boat left on hard standing in romania over winter. Being under voltage for a few months killed them.
Last year in the spring while on the danube delta I did a quick fix by rewiring to an old 110amp good quality starter battery I had as the boat liveing bank. This has lasted us through this year on low power usage overnight.
It’s time to get a better setup.
