First off, I found the spec sheet for the lithium batteries (Amita model AM048040) in my EVT:http://www.thierry-lequeu.fr/data/AM048040.pdf
With that in mind, does the 80 A fuse not make sense? I guess what I'm asking is this: is it safe to ride the scooter, for any length of time, pulling more than 80 amps? I worry about the batteries and the motor in a case like that. I wish I had a Doc Wattson, or similar, so that I had an idea what kind of current the motor pulls under different, local riding scenarios.
As you've had your scooter for years, and you have a very good idea of what goes on, would you share some of your data?
Tomorrow I'll have the opportunity to buy a 60, 80, 100, 125, 150, 180 or 200 amp fuse to replace the blown one. According to the battery spec sheet, the peak discharge is 200 amps and the continuous discharge is 70 amps. Seems like the 80 amp fuse is ideal: likely the reason it was chosen by the manufacturer. On the other hand, I do want to be able to ride the scooter with a passenger up some minor hills.
I don't understand why the previous owner, in all of her 8112 kilometres, including riding double many times, in the same city in which I live, never had this problem (furthermore, my girlfriend and I together weigh less than the other couple). It confounds me.
I hope I am not sounding like a whiner; it's really not the case. I have been building and riding electric bikes and scooters for more than 10 years, and I've never been able to grapple with the competing ratings of batteries, controllers and motors. Throw volatile lithium into the mix, and I begin to lose my nerve!
