Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

This is why I mentioned that they are better off having one independently tested.
One would have thought that opening the case and seeing the bits of wood, cardboard, tape and hot melt glue might have been an itsy-bitsy clue.

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

Well that clinches it, Kilowatt Labs is a scam. Given the tenor your initial comments here, I'm not clear on whether or not this is sarcasm, or an acceptance of what the known facts are telling us :| I'm assuming sarcasm though. weber beat me to the punch on the image search. Here's another site wi...

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

Kilowatt Labs have a lot of work to do and it appears it's the company founders who are shooting themselves in the foot so far.
Using a $10 / month hosting service for a supposedly international concern is hardly a good look.

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

OK, so I've been thinking about the whole lithium battery backup to mitigate against leakage concept that Kilowatt Labs talk about in their material - it bothers me. I did a couple of simulations and found out why: Assumptions: 3.5 kWh of total storage, initial voltage 60V, leak resistance 250 ohm. ...

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

They have not provided me with any evidence .. All of the evidence provided to date indicates that the individual storage devices are LTO cells. We've seen zero evidence that any supercapacitors are present. LTO cells seem a reasonable technology, but you should note carefully weber 's post above r...

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

Thanks weber , for those informative posts. Thanks also Nictron for your posted documentation, which further demonstrates that the Kilowatt Labs product cannot contain 3000F supercapacitors, which are huge compared to the LTO lithium batteries that it does contain. I'm sure that you will be pleased ...

At least this wouldn't happen with the supercaps! We haven't seen any flammability testing with any supercapacitors (as we've established here, the Kilowatt Labs product contains LTO lithium batteries, not supercapacitors), but Paul did post a video to youtube showing the ruptured LTO cell electrol...

Yeh cause having a range up to 85deg and running at 85deg for prolonged lengths is equivalent. :lol: That's right - it absolutely is supposed to be, for this kind of (supposed) component, as comprehensively explained above. Since what we are discussing is really a just lithium battery though, not s...

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

Thanks for your efforts in continuing to provide these videos, Supercaps . I'm afraid that I must concur with weber 's analysis though - your fast charge test is completely consistent with an LTO cell that is being charged well outside of its safe zone (you really should enclose the cells in an expl...

Re: Family car to EV Mazda Tribute conversion

Apologies if this is a silly / simplistic question (disclaimer: the closest I have come to the controller and motor you're using is seeing pictures on the internet), but: do you have the correct motor type code set in the controller(s) for the AC50? My understanding is that using a code for a differ...

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

What would a hybrid super capacitor graph look like then? Could there be more than one type of curve that they could produce? Every curve you'll find has regions that are capacitor-like. At higher currents, they become more and more capacitor-like. Feel free to provide us with counter-examples. Let...

Nice sleuthing there, @weber.

And (Oh, for goodness sake) you can actually see the 'h' on the end of '1000mAh' showing, as the sticker doesn't fully cover it.

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

It was for 10000. Multiply that by 100 for the number that Kilowatt Labs would order, and drop the price accordingly. You do understand the "from" pricing on Alibaba, I take it (?), but in case not: the lowest price is for large quantities. If you can easily find "from $1" in 10 seconds on Alibaba,...
