Defiant ST Spare Battery Light and Compact
By gilstanden on March 12, 2026
Totally happy with my spare battery for my Jupiter Defiant ST.! I found a great bike bag on Amazon that is a rear rack bag, but also can be instantly removed from the bike and used as a backpack so that I can take the spare battery with me when I'm away from the bike.
