We currently have a 440Ah lead/acid house battery bank and a lead/acid starting battery that I want to upgrade to a more maintenance free battery type. Can you provide an opinion regarding the advantages/disadvantages of lithium ion vs carbon foam batteries in the marine setting? Since I am looking long term and planning to keep the boat, a higher initial cost is acceptable if the benefits are significant. - Pete
I’d suggest the Lithium makes sense over Firefly if:
All those benefits are potentially offset by large upfront capital costs. Otherwise, I’d go with Firefly AGM. – Jeff
