Hello. I'm new to this technology. I bought an Xtreme XB600 from a guy a few weeks ago who claimed that his wife didn't want it and that he had charged it only five times. He seemed like an honest and technically oriented guy, so I bought it. I started keeping a charge cycle book of my own so I'd know the estimated lifespan of the battery as I used the machine. My log tells me I've charged it about ten or twelve times over a six week period. I rarely drove it more than seven to ten miles per charge and the meter was never below about one-third drawdown when I charged it. I was also careful to plug in and unplug from the outlet first when hooking up the charge.
Yesterday the battery crashed after I'd driven the bike a couple miles after a full green light charge. It was a warm day and I was cruising along and the thing suddenly lost about 80% of its power and started making an abrasive sort of noise. So maybe I bought the thing from someone who lied or maybe it's just a piece of crap.
I hooked up the charger again after rolling it home and got a green light a few hours later, but I haven't driven it yet. Can anyone tell me if it sounds like my battery is fried for good or just being tempermental? Thanks.
That DOES NOT sound like a battery problem, alas. Does the wheel revolve freely with power off? (no abrasive noise) If noise, you have either a bearing or brake problem. Check the following axle lock diagram:

If noise only under power, you may have a hall-effect sensor problem, perhaps as trivial as an unplugged connector, perhaps inside the wheel motor :( Connector health is a continuing problem. see http://visforvoltage.org/forum/7914-regular-connector-inspections-yall
Battery failures tend to be fairy "soft," with only a premature and fairly sharp drop in voltage.

Thank you Mark! I will look into these issues ...
