So, i'm riding my zapino a fair bit more these days (yippee!). I've only had it about 2 months, and previously had only been riding it to two locations (3.2 and 3.9 mi each way respectively) and charging it in between each ride.
Yesterday, i went from home to location 2 (3.9mi) and back, and then immediately from home to location 1 (3.2mi) worked an entire day and then rode home (3.2 mi, total 14.2 miles). I ride it in the "unlimited" setting and pretty much have it going full throttle for most of all rides. On the last quarter mile or so of the ride, the throttle started acting funky. When i would apply the throttle, the scooter would accelerate normally, but after about 2 seconds, it would stop accelerating as fast and would accelerte much more slowly, and would not go faster than 25mph or so (almost as if i had flipped the limiter switch).
During the time it was doing this, i noticed that the battery gauge would dip into the red when first applying the throttle, but then after the acceleration slowed, the gauge would be in the yellow.
I didn't see where the gauge was (under load or at rest) before this acceleration issue started happening.
One other note is that I bought the scooter used, and he only put 150km (yes, 150, not 1500) on it. he said he took good care of the batteries, though i don't know exactly what he meant. I looked at the batteries are the green silicone type.
My question is: Is this behavior (acceleration cutting out) normal when the pack gets low? If not, is it an indication of another problem?
