Ordered an electric 'motorcycle', err... scooter

[ClodMaxx]

i'll find more out about the batteries when they contact me to get payment for shipping. (memory, how long it can sit without a charge, etc.) it looks like Kelly includes a charger in their kit, but i can't find anywhere on kelly's site about what batteries it charges.

edit: ahh, here we go:
