Cycle is back out for spring!

Since today had such nice weather, I went and picked up my EV Cycle from my storage unit.

I turned the key, and did just a real brief ride around the parking lot to make sure everything was still working. It rode fine, but the 12V system wasn't working - no lights or horn.

I usually "drive" the cycle up a ramp into the back of my S10 pickup. That is, I hold it steady and steer it while lightly pushing and turning the throttle very slightly, it climbs right up the ramp.

When I was doing this, the motor stopped working. !?!!?!?
Weird, but I got it up the ramp and lashed down. Once I got home, I put the multimeter on it.

2 of the 3 batteries were great, but the third was at 5.5V!!!!! Under load the total pack voltage must have dropped below the cut-off voltage for the controller!

Something must have had a small draw on that battery while it was in storage. The volt meter left on? Who knows? Next winter, I will have to COMPLETELY DISCONNECT the batteries for storage.

Needless to say the battery is on charge right now.

We still have a couple of snows left before spring, but maybe I can get a ride or two in before the next storm hits.
