I used two such batteries in parallel (same voltage, double current) for my hot wire cutter.
My batteries come in 2, 4, & 6 AmpHour sizes at 18v.
Most lithium batteries for a camper/van are 100AH minimum. So you can see the big difference.
Perhaps as a small portable power pack, but for solar/alternator I couldn’t see it work. My Bluetooth speaker runs off these and kicks out juice for an iPhone all day long (with charging port). Which is quite nice for extended trips.
