Just charge to 50%, disconnect, and put in basement. Top up before winter. Done.

Theoretically yes, but careful! UPS chargers are designed for lead-acid. Without voltage adjustment, lifespan will shorten.
Frankly: pretty dumb. Don’t permanently parallel 100Ah and 120Ah — you risk trouble for little saving.
It works, but check your wiring and fuses first. A continuous 30A load in a van can heat things up, so route everything properly.
140Ah LiFePO₄ keeps voltage super stable and has great efficiency. With the right inverter you can run heavy loads easily.
@Dennis.Fuchs LiThink LiFePO4? Sure, they’re basically built for that. Low self-discharge, stable continuous operation, solid BMS — works fine.
