Description

This 24 volt battery pack is a replacement for the Razor MX400 Dirt Rocket electric dirt bike. Choose two 12 volt 7 Ah batteries, or upgrade to two 12 volt 9 Ah batteries for up to 28% more runtime.

Razor uses a different wiring harness on later MX400 versions, so check your version before ordering. Your Razor product ID is on a barcode sticker, usually on the battery cover or under the frame. The 7th and 8th digits are the version number (01 = version 1, 09 = version 9, and so on).

The pack uses Universal Power Group (UPG) sealed lead acid AGM batteries that are maintenance-free and spill-proof, and it is backed by a one-year warranty. To prevent damage, it ships unassembled with protective terminal caps, and the wiring harness needs to be installed. Instructions are included.

Razor part numbers:

  • W15130640003 - Batteries
  • W15130412003 - Batteries with harness, versions 1-32
  • W15120040003 - Batteries with harness, versions 33+

RazorMX350 replacement battery.

Worked perfect for the application and it shipped very quickly. Would have been a perfect score but the system did not come pre fused like in the picture.
