Thanks for the info Base - have to say after 3 years, my battery seems perfect, but I do take extra care of my Radrunner, I don't go our on trails if it is wet, I keep my Radrunner indoors in a heated garage, I don't even leave my radrunner on it's own! (I know - Scary) I always charge the battery in situ, with the correct (original) charging cable, so I do try to look afetr My Radrunner as O guess the company would specify.
Appreciate the warning.
Always Ride Rad
