Vehicle | Steele Quad This is a mini atv with extensive upgrades and modifications |
Motor | Permanent Magnet DC Originally a 24V 750W motor from a golf buggy, it has been over-volted to 50V. Capable of handling 110Amps. Have tested it to 132A. Maximum power acheived has been 5770W when accelerating. |
Drivetrain | 25:1 transaxle-motor unit with built in differential. |
Controller | Yi Yun 24V - 60V DC controller. Can handle short periods of around 100A. Tested to 132A. |
Batteries | 8 x 6s Lipolymer packs, 50.00 Volt, Lithium-Polymer Each pack is a 6s 20-30C discharge RC aircraft battery. The entire system is 2S4P making a 50V 20Ah High discharge pack. Peak constant discharge is rated as 400A, Short burst peak is 600A. Fully charged the pack is (4.2V x 12)= 50.4V. The pack must not go below 36V (3.0V per cell) as Li-poly batteries become permanently damaged if discharged below this. I have 2 low battery alarms on different packs that signal when the cell voltage reaches 3.5V per cell. Batteries can be charged at a max rate of 2C - meaning half an hour. Each of the 8 packs weighs 600g. Total weight = 3.6kg and has a capacity of 1000Wh |
System Voltage | 50 Volts |
Charger | Turnigy Accucell 6 |
Instrumentation | Cycle wireless speedometer. 2 Battery monio tors with low voltage alarms |
Top Speed | 20 MPH (32 KPH) The 25:1 gear reduction ensures that a safe top speed is reached very quickly, providing exceptional torque. |
Acceleration | 0-20mph acceleration timed in approximately 2 seconds. The torque delivered by the system originally lifted the front wheels up (throwing the rider off the back!) The rear drive wheels were therefore extended further behind the drivers seat. |
Range | 30 Miles (48 Kilometers) Upto 30 miles is acheivable with the 6 batteries currently used.Vigorous driving will empty the packs in approximately 5 miles. Energy available = 750W/h |
Seating Capacity | 1 |
Curb Weight | 0 Approximately 35kg |
Tires | Four 18inch quad wheel tyres. |
Additional Features | Due to motor over-volting there can be a significant build up of heat in the drive motor. A cooling fan blows air directly on to the motor casing providing a cooling stream of air surrounding the case. |
