Gen 2 Flux Mopeds DIY Special

by Ben N on December 2, 2017

Recently, I’ve had a fair number of people asking me about electric scooters.

Not only are scooters fun to ride, but you don’t need a motorcycle license, and they are often cheaper to insure and title.

That’s why I was excited to recently hear from Matt at Flux Mopeds. A while back, they had a few of their scooters available for sale, but WITHOUT battery packs. For anyone who could build their own battery pack, it was a great, inexpensive way to get into an all-electric ride without a lot of money. I got one of the scooters and built a pack for it from some Nissan Leaf cell modules I had. Since the scooters were originally designed for a removable pack, they feature a pair of 50A Anderson quick disconnects and DC circuit breakers, making connecting your own pack very simple.

Here’s a playlist of videos from working on one of those scooters:

So now, Flux again has a few of their scooters available, sans battery, as a DIY special. These are now the Second Generation EM1 mopeds. The second gen features a Sabvoton brushless DC sine wave controller.If you can assemble your own pack, you can get a great deal on an electric ride. They are only charging $730 each. These are BRAND-NEW, with a real VIN, all ready for street-legal riding EXCEPT for the battery. Buy two or more and they are only $680 each!
Visit for more information. If you are interested contact Matt at

Get them while you can, and tell them Ben sent ya!

Hi Ben,
I watched your videos and would really by one of these ‘battery-less’ Flux scooters.
The problem – I have never built a battery pack and am looking for some advice, how and where to get the right batteries and how to put everything together.
Thanks and Best Regards,

Hi Alex,
There’s a lot of different ways to build a battery pack, but the first thing you need to do is educate yourself! I highly recommend Micah Toll’s DIY LITHIUM BATTERY BOOK.
Battery technology (and Battery Management Systems to go with them) have changed very quickly. The various electric bike forums tend to be some of the most useful for learning about batteries. Check out the Endless Sphere forum.
Lastly, see who you can meet up with in the real world who knows more than you about batteries. Try finding a Makerspace or Hackerspace or any kind of related club that has members with interest in electronics, batteries, EVs, etc!
Good Luck!

Any chance one of these flux mopeds sans battery will go on sale again? I’d love to build an electric car, but I think it is way to big of a project for me to handle. I think a good way to get into EV’s and conversions is by adding a battery pack to an existing vehicle.
