No shot of the outside while doing it.
So 0-100 in 7sec while off the ground :lol:

The rest of the video is of a hatchback slowly driving around out of focus.

Bad cameraman :roll:

Iv'e seen people with better footage trying to prove their over unit motor working.

20KW BLDC Motor
I haven't seen anybody say they like these motors - I haven't looked recently tho..
The motor by itself seemed overpriced for what they are.
But as a motor+controller combo it is probably cheaper.

Evpower do a Me1507 pmac motor kit. 13kw con, 50kw peak.

So unless anyone here points out a flaw in my working out that's what im going to get
And that should be fine.

Sometimes the odd PMAC motor does turn up on fleabay.

Don't forget that the 6kW will be at a...

Yep it's a lot of work getting though silicone in the junction boxes. And it may not be fixable anyway. As a reconfirmation it is the panel you could measure with a DMM the PV output before charging then after the 20min when panel cuts out. But it sounds like the result be will be the same - new pan...

Well its their own fault for taking forEVER to make them.

But Tesla and Kona would be a different market.
Sure some will jump.
That will come down to:
1. If they had that choice of cars to start with.

Re: TE Connectivity contactors

So I ended up buying 5 of the mini-K contactor. They were about $25ea. Sad part was I decided I also wanted to isolate the charger from the pack when not charging. And now I can't get the mini-K contactors for $25 anymore - they are more like $100+ So I had another look around for some more smaller ...

Re: Hyundai Australia Kona EV info

yeah as far as hatchbacks go it's ok.
Probably the best electric one anyway.

So as far as I can see the difference between a hatchback and small suv is:
Snub nose
Impossibly small window at the back to make it easier to run kids over
Larger wheel arches
And whole vehicle raised UP 2-4 inches.

Re: Aux battery charging problems

As an off chance it still could be the battery. Lets say one cell is dead and has a typical output of 1.0V. So when you charge to 13.5v that means the other 3 cells are charged to 4.1V. As this battery has an internal BMS it could be doing something when it detects a fault. So it may take the 20min ...

Re: Aux battery charging problems

Well I figured if I ask enough random questions I'm bound to get somewhere :oops: Given the battery does charge and both solar controllers are doing a similar thing it does look more towards the panels and its wiring. The only other question I didn't ask were: 1. Did it ever work? 2. When did it sto...

Re: Aux battery charging problems

Ah ok.
12V 90W solar panel.
Do you actually expect that to charge a 12V battery to 14V?
Most solar controllers will accept a higher voltage (24V PV panel) and drop down to 14V.
Usually they don't boost a 12V panel up to 14V.

Re: Aux battery charging problems

Ok there seems to be missing information here?!?

Can you actually charge your aux battery to 14V by any other method eg lab power supply?
Can you measure the individual cells in the Aux battery?

The reason I ask is it may not be the dc/dc OR solar controllers but the AUX BATTERY.

I'm not too keen on your wiring panel at the top of the rack being made out of wood. It looks like at least one line is actually mounted to it through your brass bar. Wood absorbs moisture. I'd replace only that part with acrylic or polycarb or use another iso mount bar. Otherwise very nice 8-) I ha...
