Fascinating. I bought Lifepo4 for a trolling motor battery box. Three 20 AH batteries in series. Just did a test and ran a 3 amp load for about 19 hours before the inverter beeped and shut down at 10.9 volts. That jumped up to 11.3 volts when I removed the load. That was pretty close to the 60 AH rated. I’m probably losing some power through wiring. I paid $200 for the three batterie and of course a NAPA 62 AH marine battery costs half of that. But my whole battery box weighs 22 lbs instead of 44 just for the battery. Plus these are guaranteed for 3 years and slated to last far longer. So a decent trade off. I’m going with 2 Lion Safari batteries for the RV that fit the group 24 space and will get 210 AH with a progressive dynamics charger for lithium’s and a dc to dc converter for the alternator side. A bit expensive but a good amount of power to use, compatible with my portable solar panels and hopefully a long life. Since this RV is new to us I’m willing to spend more to not have to switch out the batteries every 3 years or so.
