I just got a Trojan group 31 AGM for my camper. 100 AH is awesome. 200 would be better.
It will run the fridge on DC all day while driving, and it will still be at 12.3-volts at the end of the day.
The lithium ions are nice, but I talked to a battery guy at the battery store, and he said they are too expensive, plus you would have to have a special charger/converter for them.
Progressive dynamics makes the converter for them, but I still think the technology is too pricey at the moment.
Not correct. I didn't say Lithium-Ion (which does take a special programmable charger). I said LITHIUM-IRON which does not. Lithium-Iron batteries charge just like a normal flooded cell / agm. No difference except you can completely drain a Li-Iron battery without no side effects, unlike a conventional battery when discharged below 50% starts gassing off and producing lead sulfate which eventually shorts the plates.
Reading the voltage on a battery is a poor indicator of actual charge left. You could be well below the 50% threshold and be unaware of it. You need a unit that is capable of reading capacity left, not voltage. Only 2 I know of, SeeLevel and Trimetric.
You need to educate your battery guy on the new technology.
When my Trojan(s) expire. I'll have 2 in the battery box. Hopefully, by then, the price will come down a bit.
