X2 on that. Love mine and had it in the garage below freezing many times. Not using the recommended charger either. I think my charger is a c-tek peak charger, a lot like a tender. In a pinch I drained it too low and used a 2 amp car charger on it at the lake. Still works like a champ and I leave it hooked up all the time as well. Flame TL ign. I have another new one for a backup just in case, but no need yet.
