UPGRADE your SX500 Razor 5+ mph CHEAP, for $65 hit 21 MPH!

Описание: Upgraded a friends Razor SX500 from 36v to 48v for $65.
4th battery for $30
48v lead acid charger for $30
2 longer bolts for lower bracket for $5
Reconstructed the lower bracket to mount the upper batteries. I used spacers (wood) under the bracket above the lower batteries for space over the battery terminal ends.

When first run it was 15mph and a final run of 21mph. Most SX500 and MX500 will run 16mph in stock form.

ONLY stayed with Lead acid because the 3 batteries were almost new.
UPDATE!!!
Charger pins did not line up with the factory port. Need to resolder the negative from number 2 pin to number 3 pin on the charge port on the bike. OR find a different charger.
