Battle born and dragon fly lithium are built in the same building. One is on one end and the other is at the other end. That’s what I was told a couple of years ago when I bought the dragon fly lithium batteries. A lot less weight and deep discharge and quick recharge. Glad that I changed over from lead acid. Supposedly the battle born are residential where dragon fly are commercial. That’s what I was told by my dealer.

Please keep in mind that if you have an inverter to change dc to ac, you would be able to to keep your o2 concentrator working. But to keep the batteries charged up, you either need to have enough batteries to get you through the night and then charge with and on board generator or several solar panel to recharge those batteries

What kind of rv do you have. Fifth wheel or motor home. Does it have a generator or room for solar panels

I only use my concentrator at night

I have four lithium batteries rated at 100 amps each or total 400. Gives me between 4800-5000 watts of power. I also have solar panels on the roof of 5th wheel and a 2800 true sine inverter. The fridge is 120 volts. I also have the inogen in home concentrator which draws around 120 watts and CPAP which draws total over 8 hours use of 380 watts. All together, when the sun goes down and no charging, with lights on and tv along with the fridge operating, total draw is 20-22 amps dc. So from around 5 pm until 8 am my total draw brings these four batteries down to A total draw of 300-325 amps. You may need to rethink this joule box as it may not provide enough power.

my wife has been on champva since 2016. Just show her Medicare card to physician or hospital and secondary show the champ va card. Works great and no problems. If you need meds, then get you doctor to do emeds and it goes to champva to be filled. Call their number to give them you current address if you are not at your home address. If you get a prescription from a doctor out of your area that you only need a 10 day or so prescription and you need it right away, use optimum va prescription. You do need to find what drug store can handle the filling of your meds. They have a drugstore locator on line. I believe optimum charges an annual fee of $50. Plus sometimes a couple of dollars copay. All this is in your champ va handbook
