Battery & Charging
The scooters battery system consists of two 12 v sealed lead acid rechargeable batteries;and even though this is why of the reasons why the price of E300 is so low, investing in a good Lithium battery is a very good idea. The SLA batteries are old-school, they’re reliable and have a lot of power (that’s why they’re in your car), but they’re far too heavy for most modern scooters.
How do you charge the battery?
You get a proprietary charger with the scooter, and just leave it plugged in until it charges. The maximum charge time is 12 hours, and be sure not to overcharge it. SLA batteries, when overcharged, will release harmful acid particles in the air. It’s best to recharge this scooter in the garage, not the living room.
How long does the battery last?
These batteries will give you only about 40 minutes to an hour of riding time, and after that it takes 10-12 hours of charging for battery to be fully charged and ready to use again.
How to make the Razor E300 go faster?
You can use aftermarket parts and mods to modify your E300 scooter, but those mods are not covered by warranty and there’s a very good chance you’ll destroy your motor, your ECM or your batteries. To make it go faster, you need more powerful batteries (more voltage means more top speed), a stronger motor that can actually use that power and not burn out, and a better ECM that can handle that power and transfer it into the motor. A new motor will also require you to modify the chain, and making a mistake there (using the wrong chain) can get it to lock up and fry some component.
Only attempt to do so if you’re really good at electrical and mechanical DIY, as just upgrading one part (eg. the battery) will produce a lot more wear and tear on the other components of the scooter.
In short, while it is possible, it will make the scooter very unsafe and even seasoned DIYer fry their scooters often.
