I have a solar setup that includes two lifepo4 batteries in parallel that power a very small freezer and a couple 6w led lights on motion sensors. After several cloudy days they need to be brought in and recharged with a battery charger. When I do that, I hook up a two year old agm that has been used a lot. It always seems to last longer and it’s significantly smaller. Is there a way to tell if your batteries are defective? I also get off charging info from the MT50.”(video) when running the LifePO4 batteries…volts bounce up and down with no draw on the system.
