Razor MX650 battery tray upgrade — clean custom battery installs

Running a custom battery in your MX650? Stop strapping it to whatever's down there. The Ampirra tray gives it a real home — plus a hidden AirTag mount so your bike can tell you where it went.

1

Open up the battery bay

Power off, unplug the battery connector, and open the MX650's battery compartment. If you're still on the stock lead-acid bricks, this is the moment they retire.

2

Pull the old setup

Remove the stock batteries and any straps, foam, or zip-tie engineering holding your current battery in place. You want a bare bay before the tray goes in.

3

Drop in the AirTag first

The underside of the tray has a built-in AirTag mount with double-sided tape already applied. Peel, press, done — once the tray is installed, the AirTag is completely hidden. Easiest anti-theft upgrade you'll ever do.

4

Mount the tray

Set the tray into the frame — it's shaped for the MX650, so it sits where the stock batteries lived. Fasten it down so it doesn't shift under braking or landings.

5

Strap your battery down

Use the multiple strap slots to lock your battery in — the slots let you position straps for whatever size pack you're running. Route your power leads cleanly, reconnect, and give the battery a hard shake test before you close it up.
