Awesome!

Best video, very detail explanation

I have an e100 I'm building to get to 30mph and right now all ive hit is 20mph. I just have front brakes right now, and you're definitely right about needing discs lol. I have to slow down a whole business day early

You gained a new sub

Leaving lithium batteries at full charge will plate the anodes and significantly decrease battery life span. If you leave them at about 60 - 70% when not using them they will last a lot longer. If you want a lithium battery that will last decades look into lto scib batteries. They are incredibly safe and will not catch fire or explode even under extreme stress. They're not as energy dense as lithium ion 18650 but can be charged and discharge at much higher aperage and have a life cycle easily 15x longer than lithium ion 18650. I like what you're doing. And yes 30mph on razor scooter is not for the faint hearted. I got an old 10" wheel, full suspension off road maf scooter and have done a lot of work on it. I put in a 72v 20ah akkupack high drainage cells, bought a kelly KBS72151E brushless controller and a 72v my1020 brushless mid motor. The battery was too long for the body and couldn't keep front end down, so I built a new longer body out of 6mm aluminum plate and angle. At full power (12.4kw) it keeps ripping the inner tubes so I'm going tubeless with 11" wheels to calm the torque a little. With the 10" tyres it hit 72mph so with the new ones I'm probably looking at a top speed of about 77mph. If I go out on it I always gear up now. Looking forward to see how it turns out. Good luck mate and stay safe.

Good tip!

I got a broken Swagtron Swagger 3 (cracked frame, stable 36V 6AH Li-Ion pack tho) from the thrift store for $19.99, then today I just picked up one of these E300s scooters for $22.99 (good frame and tires, bad SLA batteries), thanks for the insights. I already have a 36V Lunar Scooter LS 1200 as well. They offer a hill-climb gearing kit too.

Wait so are you still using a 24v 500w motor and do you have a link for the batteries

Hiya so you can have 48v batteries and a 36v controller? I thought they had to be the same. I want mine the same as yours with really good torque for hills and still a fast speed. What is the best setup you have done for this 😊xx

Awesome builds. I'm looking to build three like the "Battle Scooter" with the meatier tires and lower gears; my 14 y/o is a little bigger than me at 6'1" 215# and he won't be driving for a while. We have slight hills and the 65t gearing should counter the weight and tires. What did you do for your brake set-up and thoughts on thumb throttle? --THX

Can you describe how you attached the discs to the wheel?

@NortheastVintage

Disc brakes are a must as soon as you modify it from stock. There are threaded brake disc mounts that you can buy on eBay to mount the disc onto the wheel. For the caliper, use a mtb caliper and fashion a mount. I welded mine onto the frame.

That should really rock! I’m running 52v lithium ion batteries on a 500w motor now with disk brakes!

How do those batteries fit in the case? Did you make a cover to fit it? Last question got link for it? I'm really interested.

I had to drop the bottom of the case by cutting and resending the steel support bars. I’ve since gone to lithium ion batteries which are smaller, lighter and more powerful

When using hoverboard batteries can you use the factory E300 charger? I'm pretty handy but don't know much about electrical

No. You need to use the hoverboard charger. It’s a lithium specific charger.

@@NortheastVintage one last question! Would the 36 volt batteries be too much for a 350 watt motor and 500 watt controller?

@22:20 Regarding your 48 V over-volting, you stated directly that you do it to get higher speed. Couldn't you easily get whatever speed / torque ratio you want with mechanical gearing e.g. the chain sprockets; which are standard parts, cheap, and readily available, very robust? "Torquey as hell", just trade that torque for speed with the gear ratio, that's literally why gears were invented. Then you wouldn't have to resort to "electrical gearing", e.g. over-volting, which is running the motor well beyond the rated voltage. Motors have ratings (voltage, current, power) for a reason. Now that you've got those motors welded to the frames, it seems like it'll be more difficult, troublesome to swap them again once they release their smoke. And, you're over-volting the motor controllers, too? Those things are also susceptible to failure for the same reasons.

I totally agree with you Scott. "(Voltage, current, power) for a reason" 36VDC controller Maximum Continuous Coil Voltage (-20%/+30%) = 46.8VDC, so 48VDC battery to 36VDC controller may burn or maybe not, it will be depending on the quality or rating of the part. 36VDC to 24VDC controller will burnout the coil and the on/off switch light indicator. All the Mathew's earlier motor failures came from unprotected or improperly protected circuit breaker when some batteries were low or going uphill giving too much stress to the motor.

​@@charlieson3394easiest thing to do is swap the 11 tooth motor sprocket for 12 tooth, 48v battery pack, 48v controller, then run a 36v motor a 33% overvolt will never kill a good motor as long as it's kept from overheating and kept within amperage ratings
