I offered 75. They came back with 90 like yours. So it looks like that is there minimum.
I ordered 3 of them. I have never used or programmed any of these so it will be a fun learning experience. With minimal investment.

I'm curious if you can change the voltage permanentely like I did this before with the help of Remmie on other Eltek Chargers.
All you need is a Arduino with CAN bus.
Here's the Arduino sketch and info:

All credits are for Remmie, who reversed engineerded this all. I just added some text so everybody can understand and use it.

Thanks for the Arduino sketch. I have never used one before so will need to learn for sure. I found the original post that Remmie had for the programming

I got my 3 units today.

Wow what a nice packing and bubble wrap protection around those!!

Will play with these over the next weeks.

I'm pretty sure these can also be permanently programmed to a new defaut voltage. I succeded to do that on my Flatpack S with a simple command line and my IXXAT CANbus interface.

Sounds great Doc. Mine are on the way also. Just shipped yesterday from Texas. They should be here Monday. I read thru the whole post of the homemade supercharger to try to learn the programming. I found the leonardo board but from a UK online store. Does the ixxat work similar?  I will have to look that one up. I since the new charge tank for the 2018 wont work on the 2017 this will be a good option for faster charging.

yes the IXXAt is one of the top CAN programmer, It work for nearly everything.

Thank you Doc.  I ended up ordering the Leonardo Can Bus from Hobbytronics. This is all new to me so spending the $200 on the IXXT was a bit much for now.   Still reading thru the Endless Sphere write up on the programming and trying to digest.  I may have some questions for Doc and wijnand71 if that is ok when it gets time to see if I can set the voltage?  Keep us update Doc if you get to work on yours with the programing and how it went.

Haha, yes the Hobbytronics CAN interface is really cheap and works also great. Proffesional Interfaces are very expensive.

There's a how-to included in the Sketch. If you open the sketch with the Arduino program you will see the instructions on top of the file. You need to fill in the serial number and the desired voltage. I copy below the instructions wich is in the file:


// Eltek Flatpack Permanent Voltage changer, Code By RHO
// Used Arduino board is a Leonardo CANbus Board, abtainable at http://www.hobbytronics.co.uk

// The procedure for permanent default voltage change is :
// You have to have a connection to the CAN-bus (obviously)
// if the serial number of your Flatpack is 123456789012
// Change line 46 with the serial nr in the code as below
// send 0x05004804 0x12 0x34 0x56 0x78 0x90 0x12 0x00 0x00 (to log in to the rectifier)
// send 0x05009C02 0x2B 0x15 0x00 0x80 0x16 (to set the permanent default voltage)

// upload code to Arduino
// disconnect Arduino from usb so it powers down
// First power on the Flatpack
// Then power on Arduino via usb

// After about 10 seconds or so the output voltage should change to the new default voltage.
// Now wait 30 seconds and disconnect the power to the rectifier.

// When you start up again the voltage will default to (in this sketch ) 57.5 Volt. The default voltage is determined by the last 2 bytes of the second command.
// Multiply your desired voltage with 100 (57.50 => 5750).
// Convert this number to HEX values (5700 => 0x1680). switch the two bytes (0x1680 => 0x80 0x16) and you have your code for setting the voltage

// NOTE: Some Flatpacks needs to run this procedure several times to change the Voltage.
// Sometimes the Flatpack shows an yellow led, but no Voltage change. Just repeat the procedure until it changes the voltage.

Thank you wijnand71. I downloaded the Arduino software on my computer and was able to see the sketch like you posted. I just need to figure out which connections on the Leonardo hook up to the CANL and CANH connections when I get the equipment this week.

Oh, but thats really straight forward. Its all printed on the pcb.
Included are some screw terminals to connect/disconnect wires easy.

Great information.  The chargers and the board should be here tomorrow.  Not sure when I will get a chance to play with everything.  I may bring the chargers and board to work to work on at lunch.  We have tons of 240V to plug into at work.  Thanks for the reply.

I was googling where to buy Hobbytronics Leonardo Canbus in USA, found this... is it the right thing?

Seems not...

Not the same, if it says shield, it is an add on board for an existing arduino, this will allow and arduino to use can bus.
