Super Capacitors?

[Netvaper]

I got round that issue by buying a second revo, if it's not for you, leave it, tearing down advancements because of a single issue is a bit pointless imo.

I was just pointing out it has drawbacks and at well over €200 buying a second one is a lot of dosh so it deffo isn't for me.

Do you think these Super Capacitors are the way to power EV's?

Cheers guy. Nice find.
Same old problem though. They are high capacity and charge quickly. But can’t hold a charge. It shouldn’t be a shock. We’ve been using capacitors (chem capacitors are just the same)for many decades, in many applications. And they still can’t hold a charge for an extended period. The section Electrochemical capacitors. says it all right there. And very little of it is fixed from the mech version. Their ability, today, to deliver only 10% of the power an equivalent Lithium ion battery does, is also salient. Hence the mod only just managing 5ml per charge.

It’d be fine a some uni students project. But as a viable retail item. I’d say not for many years, if ever.
I’m guessing accumulator tech will advance, before they are useful in gear like this. But they may well be ground breaking in other areas.

I like the idea of the supercaps, particularly if they last anywhere near as long as suggested without significant aging and really can take thousands of charges.

The con, for me, is the pair of supercaps look large - and fitting them sideways makes the ends protrude - it may be a design feature to highlight the battery tech, but it' makes the mod ugly and uncomfortable to hold.

It is an interesting mod though, and I'd consider buying something using supercaps if they were enclosed, and were positioned in a format where they didn't bulge out of the sides.
