Solid choice going Fogstar. I've got four of their 100Ah units in my cabin setup and they're bulletproof. Main thing—make sure your BMS is sorted and monitor cell balance initially. Narrowboats benefit massively from the weight savings, yeah, but that 600Ah will last you ages without the constant top-up faff of lead-acid.

Spot on choice with Fogstar. Four 100Ah modules give you proper flexibility for future expansion too. The real game-changer isn't just weight—it's the usable capacity. You'll actually have access to nearly the full 600Ah without worrying about depth of discharge like you would with lead-acid. Have you sorted the BMS integration with your existing charger setup, or upgrading that as well?
