Additional Features | Disabling the scooter is as simple as unplugging the throttle button The battery is held to the metal bar with ginormous heatshrink. I put some hot glue on the bar before I heated everything to make sure the battery wouldn't slide around I did stick on a brake light and a go light but haven't wired them yet The relay has an internal led across the coil. Wired one way the led lights when the relay is closed. Wired the other way it makes a visual flyback supressor! The 8 pin connector I got from allelectronics doesn't seem to mind passing 5 amps. While the charger side has 7 small wires from the balance connector and 2 wires from the charge port, the inside of the scooter only has 7 wires from the connector. Black and red go to the main battery connection and the other five go to the balance connector. This works because the red and black discharge wires are common to the red and black balance wires. Razor must have designed this scooter for 8 year olds because the handlebars were way too short for me. So I got a piece of steel pipe that fit and I used JB weld to keep it that way. |
Not sure how long the motor will last Not sure how long the relay will last |
