What's the input voltage?

The Diginow SCv2 bricks I have (early batch, later ones may be the same)
meter themselves are based on amps, not watts or kilowatts, so even though
they are 3.3kw each, I get 3500+ watts each when plugged into 240VAC power
and ~3000 watts when plugged into a crap station that dips to 197VAC under
load.

Contact cleaner may help, or it might not.  Depends where the resistance is.

Lost my faith in Zero with my 2011 S, but regained it with my 2014 SR.  Diginow SCv2 changed my SR from a fun ride to primary transport.

It should be 3 phase 240V. I haven't measured it yet myself but I'm pretty sure that the ABB Terra 53 that are next to the motorway here delivers and doesn't dip.

The charger is doing it's work pretty good for the rest and though it extends the charge time only a few minutes I would surely like to access those last 16A.

Wise man say: measure, don't guess.

I use DROK AC displays, bought them on ebay or Amazon. 
They show amps, volts, kw, wkh.  There are color versions
that do non-contact amperage measurement (you feed one
side through a coil) and monochrome ones that only go to 16A
that are wired through and are way less bulky.  My v2 patch
panel will use the latter.

I was waiting a few days until the weather cleared up a bit, which it didn't so today I took a wet trip to the fast charger to measure. On all phases 230-234V. However I did notice that the little led on the SC is blinking red.

Did some more charges at various battery SoC's and temps but I'm still only pulling 50A...

The mystery is solved! Because I ordered 4 units my SC was tuned down a bit to avoid going over 1C while charging.

Small update, I'm still working with two units but plan to install them all when my new side and top cases have arrived. In the meanwhile I was pondering how to reduce the clutter of cables and tubes. The cables will stay for now but the current liquid cooling can use some improvement. It is effective but pretty bulky with the separate pump, reservoir, radiator and all the tubes and 12V wires that go between them(If you haven't seen the liquid cooling in action yet there are some videos of it on my channel. And now double that with four units.
I had quite a few hard and long thoughts about how to shrink it down and then I realised that I was literally sitting next to the solution:



I do also water cool my desktop and it uses an all-in-one(aio) cooler, so that's CPU/GPU block, pump, radiator and fans in one small package. No reservoir but high flow and fan speeds should be able to negate the use of that. So I'm now looking in sacrificing a 240mm aio cooler and modding it to fit on a 4 stack SC like this:



Tdp shouldn't be that much of a problem, overclockers sometimes need to funnel away +500W of tdp and 240mm radiators have no problems doing that.

Much tidier and for a v2 it could even be moved outside the top case. I'm

Your thoughts?

Found the right cooler locally: http://www.swiftech.com/H240-X.aspx



This all-in-one cooler was designed to be modular, and I've found one without CPU block. It should be a matter of connecting the tubes and filling it up and after providing it with 12V it should be able to cool all 4 units comfortably.

Thanks, Erasmo!  Good details!
