Does anyone know how to obtain any of these batteries ?? I found this company has some interesting batteries that are in the SLA size, shape, etc. but offers what looks to be DOUBLE the AMP HOURS, usinf Lithium technology. That would mean 1/2 the weight of batteries for EMAX owners, etc. According to one article it looks like Oxygen scooters will be using them soon to obtain 80+ miles of range.
