I have two Lashout Scooters. They both have been modified. One has 3 SLA 22 AHR Batteries with a after market BLC 36 Volt 600 wattbrushless motor it used to have two of these motors until one fried. The other is a 48 Volt with four 10 AHR SLA with a custom Ametex 64 Frame Brusless which just fired since I ran over the recommended voltage of 36 volts.
I also have modified these scooters with Avid DownHill Rotor Disc Brakes. The 36 Volt will go 25 MPH the 48volt will go 30 MPH. I just ordered two 48 Volt Motors from powerpackmotors @socal.rr.com I will use a dual motor plate from www.evdeals.com I also am ordering LiFePO4 pack from www.yesa.com.cn The only problem is the battery tray sizes I have. I want a 20 AH pack but the only one that will fit is the 12 AH 48 volt pack. So I am researching what range is possible with this battery. Would this unit last as long as my 22 AHR SLA B 7 B high out put SLA?
