It’s a fine line balancing between higher costs and capabilities in my opinion. If the RV has enough battery capacity so it doesn’t need a generator as a backup, then it needs extremely high recharging rate to get the batteries charged back up in short period. That’s tough on a system with 36,000 Watt-hour of usable capacity.
On the other hand, if you’re going to include a generator anyway as a backup, then why spend so much on that much battery capacity? Granted, if the cost is indeed around $300 per kWh (or lower) as Jamie reports, then 36 kWh is under $11,000, so the high system cost is coming from somewhere else.
The difference between $125,000 for this lithium system seems out of proportion with what Winnebago charges, about $20,000, for the much smaller Travato system. And even that seems high to me.
Personally, I like the idea of having just enough batteries to boondock overnight, assuming you’re going to be driving next day to recharge. Initially that’s where I see the sweet spot between cost and capabilities, or most bang for the buck.
