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.).

  • Questions

    Is this 1 or 2 batteries
    This is a set of two batteries. You also have the option of ordering it with the battery wires, or the batteries alone.
    Does the battery part number x99-0903 have different power connectors
    There are 2 different wiring harnesses available with this battery pack. For MX350 models versions 9-32, the connector is a 4-Pin, 2-Wire connector. For versions 33+, the connector is a 3-Pin, 2-Wire connector. Please take a look at the photos on this item page to see the different connector styles.
    Can you provide the dimensions for these?
    Both the 7 ah and 9 ah battery options measure as follows:

    Length: 5-7/8"

    Width: 2-1/2"

    Height: 3-3/4"
    I have connected batteries and fuse is fine and I HAVE put batteries on charge not knowing if they come fully charged when I MOVE the throttle all I hear is like a dull click . any ideas?
    Typically, due to the lower amp hours, you would need to kick start the unit as these have a push to start feature. If that does not work, please give us a call at 1-800-798-0325 for further assistance.

    Better than the stock Razor battery. It actually makes the bike go faster. Make sure you charge periodically in the off-season if you want the battery to last.

    Batteries and wiring harness are great. Only issue I had was with red ex just leaving package in the driveway by garage door in the rain with no bag around box.
