Any Advantage to Lithium with Bluetooth?

At 3500 cycles they should still have 80% of their rated capacity.

yup that's how LiFePo4 are rated. but let's take a look at that number. I have a 280 AH battery of which I only make available 80% of the available capacity so that like saying I have a 224AH battery. If I do something to lower the cycle life or just hit that point then my 280AH battery becomes a 224AH battery and if I operate it at 80% capacity to keep it going as long as I have then I effectively have a 179AH battery. which for me means that I have lost 2 days of camping if the solar is down before I need a recharge. My point is if you are able to run at 80% capacity off the start and shallow discharge why wouldn't you try to post phone that 80% cycle life marker.

I understand for some people it isn't an option as they have to run their AC and such and its expensive just to get enough capacity both in solar and batteries for that, but while if I camped in my driveway, I would be one of those people also as I am in the hottest city in Canada for summer temperatures. but I can also drive an hour and get out of the valley and be at much higher elevations where it might be a little warm during the day but cools off dramatically for sleeping which means I don't need the high capacity some do.

now in my 5th wheel I would use more power and I am setting that up with a lot more AH and a lot more solar than the camper.. I have no 120power in the camper and my biggest worry is the furnace as I do a lot of early spring and lait fall higher elevation camping and that furnace will suck up to 36AH overnight, so it is set up to be able to do 7 to 10 days of camping if the solar is not producing so generally it is a shall discharge setup with and emergency reserve capacity.. so, a perfect set up to test how much you can increase cycle life.
