I've been poking around with my Flatpack2 HE but not really got started on a build yet.

Does anyone know what the third contact with the CAN H and CAN L is? I've stuck a 'scope on it but can't tell what it is.

I assume that when taking 12V from the fan that you also need to take the corresponding ground and link this to the - output. The fan supply seems to be isolated from the main output and this ties it back in. I know this will work, but I'm sure there must be a more suitable 5V somewhere to go with the CAN bus. It's just a pain to find with all that varnish all over everything.

CAN H & CAN L are balanced or symmetrical signals, but they are not floating. Always referenced to GND, the third wire.

Aloha guys,
its me, the FPS guy

everything is dry now....

as some guys from this forum told me 14 defintily buying guys are on board with this buy i had a talk with my eltek contact.
they need 10 working days for delivery.

I did a bunch of Groupbuys allready. Including 45 Big Hub Motors from China FOB. So it helps me when you just send me details on this template below without questions.

So I did it,

paid 1.135 € via PayPal for four flatpacks S 1.800 (4*280 = 1.120 €) and delivery in Europe (+ 15 €).

Andi aka Merlin from Endless-Sphere or here Ciscone is an experienced group buyer.

So let's keep up the speed ... the weather here in Germany is already Zero friendly ;-)

Great,. I am so happy that it worked out. Gonna send you my details via PM and the money via PayPal fro two flatpaks.

Now I indeed hope that people with experience can help a bit with tips & tricks (see also the other thread about the connector).

[evtricity]

Has someone made a good  quality PCB connector board for these Flatpack S models?

[wijnand71]

On this page Merlin has some..

[evtricity]

Thanks but that page has connectors for the Eltek FP2 2000 rectifiers. I understand that the Flatpack S have a different interface at the back and will require a different PCB connector.

[wijnand71]

Not sure about any differences, can't find any online info about the connector sizing. Just sent Merlin/ Ciscone a PM.

[remmie]

There's a big difference between connector of  the Flatpack 2 HE 2000 and the Flatpack S 1800. The FPS is much smaller and the + and - output is reversed (ask me how I know  )
EDIT : the connectors look very similar in width and position of the contacts.


In this thread on endless sphere a guy has made a board for the Flatpack S

https://endless-sphere.com/forums/viewtopic.php?f=14&t=71139&hilit=ultra&start=175#p1270667

the chargers in this picture is definitely a flatpack S 1800 W

[wijnand71]

Ah, crap. But it seems too big for my plans. Anyway, I have to wait till my Flatpacks arrive, then I will create a very slim adapter/breakout for it.

[remmie]

I stand corrected. I posted the last message that the connectors are very different from my memory because the width of the 2 flatpacks is very different.
I still have 1 FP2HE and comparing that to the FPS the connectors seem to be very similar ! I'll post a photo of them side by side later

I do however know for sure that the + and - DC outputs are reversed. The CAN connections appear to be on the same position.
So take care when using a board which is made for the FP2HE and has markings for + and - output. MEASURE which is the + and which is the -

Sorry about the confusion

Ah that's my old board. I was asked if I could make the board public. It was the first one I made for testing so things are a lot more spaced out and with bigger holes. I do have a stubby version but I didn't like it as much cause it would be hard to disconnect quickly. The board has two holes for each connection so you can connect between the two FPS.
Remmie is correct, the FPS and FP2HE are a bit different.

Be safe and have fun!

Uffz, done. Took me a huge fight with PayPal for their payment fees, so in the end I used bank transfer. Money should be on your account in 2-3 days.

Looking forward to my supercharger I already got the arduino, the Mennekes plug, and the zero connector. Still need some other small stuff, but slowly it will move forward

[hubert]

bank transfer done as well. In case of SEPA € to €, paypal only makes additional complexity and delays, and possibly fees.
