Lithium batteries are a game changer from the ni-cad 'totes' of old.
Just the fact that they can dump so much, so fast.
As charge density goes up it can only get better.
I too have heard good things about noco.
Only got a chance to use them a few times.
But they certainly did work.
I'm a little leary of their small cables, but they're made for modern vehicles who's starters don't seem to draw so much.
