Just got the Booster V yesterday, first thing I did was charge it. Being stupid, I stopped charging as soon as it hit 100% on the display. I then road it until it was basically dead which was approximately 5 miles. Now I realize those battery indicators are very inaccurate it was probably more at like 50%. I took it for another ride after charging it but not to full.
Now I hear people saying you have to charge the battery completely when you buy a new scooter. So I charged it up until the brick turned green which took close to 4 hours (Says 2.5-3.5) and like 2 hours past when the battery icon said it was at 100%. I rode it for 11 miles averaging like 19-20mph on pretty much a straight away no hills and that took it down to 10 percent. Did I damage it already by not fully charging it first use and taking battery all the way down or am I paranoid?
