Speaking of proprietary tech, this is what Advanced RV says...
"To develop this integrated battery system, we partnered with nearly a dozen suppliers who helped create custom products, software, and firmware."From:
Go Farther Off the Grid...I don't know how one would or could mess with an integrated battery system. Roadtrek says much the same with their developed proprietary systems. Are they messable? The actual hardware might not be so much but any proprietary firmware may be difficult to diddle with that puts all the hardware together.
My 600 ah of LiFePO4 lithium batteries are going to weigh about 170 lbs. and be located under the floor where a 125 lb. Onan propane generator would normally go. To get an equal usable amount of amp hours in AGM batteries they would have to weigh at least 500 lbs., if not more. I'm eliminating all propane as well which will be another weight savings.
