Protek 5129-19 7.6 volt 5000 Mah Hi Voltage Lipo | Pinnacle Hobby
2 Cell High voltage lithium polymer battery
This battery is shaped like an old style nickel batery to allow it to fit properly in older vehicles especially Tamiya brand cars.
The high voltage feature means that this battery is more tolerant of slight over charging or can be charged to a higher voltage for acheaving the 'hole shot' in that next big race!
