Upgrading my Super Soco TS
i am looking at ultra capacitors as my next upgrade, they are almost at the W/kg of 18650s, but i could still give myself allot more Ah (35-40 i think) the same space as 2 x 26Ah battery
best thing is, potential for full charge way under 1hr (maybe 20mins!)
The factory is just starting to ramp up production in China now, fingers crossed i will have working prototype before the end of summer!
After that i will look at controller to improve acceleration, then next year maybe look to increase speed (depending on legal checks and insurance practicalities)
What's the benefit of capacitors aside from ultra fast charging, where the question rises where can you charge so fast and how often do you really need it?
I would rather have faster acceleration / more range / more top speed than just faster charging.
there are quite a few fast chargers around cities these days - but in addition, a multi-kW charger that plugs into a domestic mains supply is not to hard to find
PS note on range. The bike should be able to hold 2 super capacitors (plus a smaller acceleration booster), potentially offering 70Ah + 1Ah - but im not that rich at the moment. - i also felt it was safer to not over pack the bike, heat will be generated, I have no idea how much - although these caps will not cause catastrophic explosions like lithium, they are expensive to replace
Thank you Nardcox, I will receive my TC in a week or two and was thinking of doing almost the exact same thing as you -swap out the motor, new controller, build diy battery (funny enough I had the same 29E cells in mind).
Looks like I can learn a lot from your project and not have to reinvent the wheel again! Thank you again, the time and effort that you put into describing and logging everything is highly appreciated (at least by me).

Yeah, do you research, it's a big 'investment'.
How much power (W) do you want to pull? 20S20P will fit in a single / standard form. I have 2 packs or 10S20P and connected them in series. See my pictures. https://photos.app.goo.gl/rWyHYPyg7BZbEREW7
Bigger is possible but don't forget you also need to house a controller. With those 2 in my 'buddyseat' it's full so then you need to start modifying the structure of the body. I couldn't mount the controller in the original location since it's quite a bit bigger.
The difference in width is about 1cm I can probably make that fit. However the axle is 14mm on the QS and only 12mm original so I would need to modify the arm. Next to that I won't be able to use the rear brake anymore since the motor itself is to wide.
I have the motor spinning, but not properly and for some reason it hits regen extremely hard as soon as I want to go past 50kmph, no idea why.
