    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 addition, you can select the Razor MX350 battery pack along with the correct wiring harness for your Razor MX350 versions 9-32 or versions 33 and up. You’ll save big on Razor battery packs and harnesses with Monster Scooter Parts.

    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. If you have the earlier Dirt Rocket, you will want our .

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

  • Razor MX350 Dirt Rocket Wiring Diagram (Versions 1-7)
  • Razor MX350 Dirt Rocket Wiring Diagram (Version 8)
  • 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+)

  • Note: If you select the "No Harness" option, you will need to re-use your existing wires and connectors; reconnecting them to the batteries by either soldering or using tab (aka "spade") connectors. For the best results, we recommend that you purchase the complete battery pack with the harness.

    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.).

    Why buy replacement Razor scooter batteries from Monster Scooter Parts?
    Monster Scooter Parts sells high quality sealed lead acid (SLA) batteries at affordable prices. Our battery packs use batteries from Universal Power Group (UPG), a leading supplier of battery and power related products in the United States for over 40 years. Based in Coppell, TX, UPG provides the OEM sealed lead batteries in critical applications such as medical mobility devices and equipment. If these batteries can meet the high standards set by the medical equipment manufacturers, you can be assured that they are of a higher quality than the OEM batteries provided by Razor, as well as the off-brand batteries sold by Amazon dealers and eBay sellers. All of our Razor battery packs 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.

    Does the battery part number x99-0903 have different power connectors
    +5
    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.
    Is this 1 or 2 batteries
    +1
    This is a set of two batteries. You also have the option of ordering it with the battery wires, or the batteries alone.
    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.
    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"

    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.
