Description

This high capacity 36 volt battery pack fits the Razor MX500 and MX650 Dirt Rocket electric dirt bikes. It includes the wire harness and wiring instructions.

The pack uses upgraded 15 Ah batteries for about 33% longer run time between charges than the standard pack, which makes it a good choice if the bike is ridden for long stretches. It is identical in physical size and wiring harness to the original Razor battery pack, so it drops right in.

Looking for the standard capacity version? See the 12 Ah 36 volt Razor MX500 & MX650 battery pack.

Perfect battery replacement for Razor MX500

Perfect battery replacement for Razor MX500. All the connections included, so it was “plug and play”. Some people wrote about one of the wires being a bit short/tight but I did not experience that at all. Hopefully they will last as long as the original batteries, which was around 4 years.

Replacement on an MX650 RZR

Product fits and works great. Connector save you a lot of time on these batteries One back cable tight as described in another review, but just makes. Could not be happier with this set-up. Install on a mx650 razor took about 25 minutes, just had to take the side panels off.

Replacement battery for Indian EFTR- jr

Battery instructions were easy to follow. Batteries included replacement harness. The higher output battery gets a lot more use per charge compared to stock battery. I’m glad I upgraded.
