Description

If you have a later Razor MX350 Dirt Rocket (versions 9+) then we have a deal for you. Our OEM equivalent 24 volt battery pack for the Razor MX350 (versions 9+) is an unbeatable value in electric scooter and bike batteries that will definitely save you some money. For one low price we will send you two new high quality 12 Volt 7 Ah batteries. Or you can upgrade your battery pack with a pair of high capacity 12 Volt 9 Ah batteries that will give you an increased runtime of up to 28%. The choice is your's to make.

In its long production run, Razor used two different battery pack/harness configurations that are not compatible with one another! This battery pack is only compatible with MX350 versions 9 and up. The older versions of the MX350 Dirt Rocket (1 - 8) use a different battery pack.

The wiring diagram for your model can be found at the following links:

  • Razor MX350 Dirt Rocket Wiring Diagram (Versions 9-10)
  • Razor MX350 Dirt Rocket Wiring Diagram (Versions 11-19)
  • Razor MX350 Dirt Rocket Wiring Diagram (Versions 20-25)
  • Razor MX350 Dirt Rocket Wiring Diagram (Versions 26-32)
  • Razor MX350 Dirt Rocket Wiring Diagram (Versions 33+)


  • In addition; your model version can be determined through your Razor product ID, which is typically located on the battery cover or on the bottom of the frame on a barcode sticker. The 7th and 8th digits correspond to a version number (e.g. 01 = version 1, 02 = version 2, etc.).

Our batteries and battery packs use MK Battery or Universal Battery (UPG) brand batteries, leading suppliers of battery and power-related products in the United States for over 40 years. You can be assured that they are of a higher quality than the original batteries provided by the scooter manufacturers, Amazon dealers, or eBay sellers. All of our MK and UPG batteries are backed by a one-year warranty. Compare our batteries to the shoddy, cheap, and unreliable batteries sold by our competition and you will see why Monster Scooter Parts is the right choice.
