My AGM batteries seem to be on their way out, and replacing with lithium seems to be a no-brainer. Having already established that AGM batteries can probably be discharged by 80% without loss of overall life (see previous post…
@SLJ - we. too, have camped for a week with no solar input (rain, too) running our 2-way fridge on our 225Ah AGM batteries with power to spare. That is what we used to get, and what I was expecting on our last trip. Instead the battery voltage dropped too low to run the Alde when the Victron BMV told me we had 70% state of…
Battleborn says this: "Most lead acid batteries experience significantly reduced cycle life if they are discharged more than 50%, which can result in less than 300 total cycles. Conversely LIFEPO4 (lithium iron phosphate) batteries can be continually discharged to 100% DOD and there is no long term effect. You can expect…
