Re: AGM batteries: Someone using them?
I never had lead acid or lead. When I bought my boat, and studied a bit, aside from cost, AGM was a no brainer. They lasted four years, and my use was very irregular. Last year, I upsized my battery bank to (7) 105Ah battery bank, AGM. I run a 10,000BTU air conditioner with it. Love it, no genset. Turns out that my engine is quieter than my single-cylinder genset too. Another advantage is that AGMs are sealed, zero maintenance and zero gas emmissions from what I have read. Good AGM bank and large alternator. More than enough for your refrigeration. Do the numbers. Good luck!
Thanks! Yes I have done the math and it looks good on paper, just wanted someone that uses them to confirm that on the reality. It seems that you have done just that
Just a last question: For your 735Ah battery bank what is the power of the alternator you use to charge them, the one on the engine?
