Great battery... I had a lithium one before this that swelled up and at the end of the day I think lithium are just too unstable and I have a bunch of them with all the model airplanes, quads, etc. Just not for my Morgan. The interstate is a champ for sure.
Isn't swelling a sign of overcharging on Li? Modern regulators should not be an issue with Li (unlike older bikes like my early wings). But you have to have a Li trickle charger, not a regular lead acid one.
