AGM Batteries and Inverter - What Is Best For My Needs?

This is one reason I kind of laugh at the people who claim LiFePO4 will last 3000 cycles. Using it every weekend of every year would be 28 years before you hit 3000 cycles. The battery will be useless because of age long before then. It may make sense for someone who is boondocking 24/7.

Running the AGM batteries down to 30% and getting 90AH out of a 125AH battery you will still get around 300 to 400 cycles, which for a typical camper used 40 nights a year means 8 years of life.
