The voltage stability you're getting is the real win here. I've got a pair of Fogstar 200Ah units in the camper (paired for redundancy, bit overkill but peace of mind), and the difference under...
@Paddy's absolutely right about continuous draw being the key metric, though I'd push back slightly on overlooking peak loads — they'll size your inverter, but continuous draw sizes your battery...
The weight saving is genuinely transformative on a narrowboat—you're looking at roughly 1.5 tonnes less than lead-acid for equivalent capacity, which makes a measurable difference to draft and...
The efficiency argument gets overstated, but there's a subtler benefit worth considering: the II's improved transformer design means better performance at partial loads, which is where most of us...
