The GoGo Endurance comes with you choice of 8Ah or Maxx 16Ah battery pack, but you can buy add-on battery packs to keep you going farther for longer.

Lithium Ion batteries are very light, so these battery packs are easy to carry and you can keep an extra in the car or even in the optional rear basket!

It doesn't matter which battery option came with your Endurance scooter, either size add-on battery will work.  The cases are the same size, the only difference is the size of the battery pack inside the case!
