Missed that .. what confused me is that this seems to be a "new" post that popped up, as the Jan 2016 is still there, and both have Jan 2016 dates ???

They posted internal pix of their "supercaps" on F/Book - https://www.facebook.com/kilowattlabs/p ... =3&theater
Odd that they copied these from a previous post they did on 26 Jan 2016, over 2 yrs earlier ! So many more questions :-)

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

... But I asked GridEdge several questions per email, so far the silence is deafening. 100 watt to run them on standby and 14 hours to heat them up before they are usable? .. In contrast the supercap is very new, exorbitant claims .... Yes. Having seen the unit, plus it's build quality (excellent),...

Re: Stray Capacitance

Hiya, Yes it is definitely a capacitance issue. I seen it a lot, especially with Formula SAE-E builds (Universities), plus my own battery packs. Because the HV section must be isolated, usually with differential "earth leakage" to vehicle 0V, there is no point "earthing" the Al case to the vehicle c...
