once these S model will become lower price these will be very interesting!
I feel lucky to have found my two on ebay for 225$ total in two different auctions

this is still VERY incredible how 3600Watts of power is so small and fit everywhere!

I would take one !

And I would offer connection board for them like for the FP2.
But I need one to prototype on.

still not that cheap. but theres no other PSU out there to beat that power/size.
how many guys are interessted if i can get that price?

Got a couple of S 1800 HE and wired them in series. They work great, but I noticed the right side gets pretty hot (at 20A DC). Might be a good idea to attach a small heatsink. Does anyone know if if the temperature is monitored in the unit and the amps will dynamically roll back above certain temperature threshold?

Edit: Found the permanent voltage setting procedure.

ok....should i start here?

20 pieces of the Flatpack "S" are on the way....

10 allready sold on motorcycle forums.



any interest again here? first ETA is 10 working days for me.


in 3-4 days i will open a new for sale thread when heres no / not enough interest.

Price is 280€ + Shipping each PSU. Coming with 6 Months warranty fresh and new from manufacturer.

How did you vary the voltage? was it sole through programming?

thanks

They come with default voltage set at 53.5V, so that's 107V with two in series. My pack is 26s or 109.2v HVC. For now, I just charge it up to 107v but I got an Arduino with a CAN Bus I am going to use for voltage fine tuning.
Also, answering my own question: a heatsink is probably not necessary. Units have high temperature and fan failure protection. It will not roll back current but, at least, will shut down if it gets too hot. We'll see how it behaves when its 100F outside.

one of the guys on the electric motorcycle forum commented on this already... apparently it will kick off if it overheats, but then kicks right back on after it cools enough. So he can just leave it plugged into the EVSE, it cuts off and cools, then kicks back on.

These units are made to be stack 3 units wide in a 1U and 2U rackmount with controller.. so these are made to operate in very compact area and the right sid eof one toutch directly teh left side of the next in this arrangement so no worrie.

Yes, my friend designed some that he's using for his charger setup. I will ask him to share the files.

I ended up making tabs with nickel and soldering them to 12Awg silicon wires. Works great and nothing is sticking out that can be snapped.
Still need to figure out the CAN BUS connection.

Hi,

It looks like the rectifier does not send the last two bytes of the serial number in the header but does something with it.
the last two bytes of your serial number are 40 81. So in my code i assumed that when the rectifier sends : 05004081, it would require the controller to respond and log in. BUT, your rectifier sends 05000081 instead of 05004081. Therefore the code does not recognise it and sends it back as a unknown command.

In the code, find the line where it says :
else if(canId==(0x05000000+256*buf[5]+buf[6])) //if CANID = 0500xxyy where xxyy the last 2 digits of the serial nr

and change it to :
else if(canId==(0x05000000+buf[6])) //if CANID = 050000yy where yy is the last 2 digits of the serial nr

That should work for your rectifier but for other serial numbers it may be different, for some it wil work for others not. that depends on what eltek has programmed. I would have to have a number of serial numbers and the responses of the rectifier to determine the precise formula the rectifier requires. It COULD be something like 0500xxyy and FFFFAFFF (this changes the '4' bit in the fifth byte to zero. In your serial number thatit would flip the 4 to a 0 resulting in returning 05000081 instead of 05004081

you could off course also change it to :
else if(canId==(0x05000081)) //if CANID = 05000081

but that would limit the amount of serial numbers the code would work with even further.

Good luck

Hey, I just bought a FP2 and was wondering if anyone has a connector for this version left.
I already have the proper CAN Module and want to program it with a ESP8266, so it will keep the FP2 all the time logged in and set to the right settings.
Additional to that, you would be able to control it via wifi and also check the current-, voltage- and poweroutput. Over the time even the delivered energy and therefor over the longterm use also the state of health (SOH) of the battery. I want to use it for an electric scooter with a 14s batterie with 10s, so current limiting will be also a priority for me...
Did anyone found a solution for a default current change?

Thank you remmie, that did the trick!!!
But I have another issue... The MCP2551 on the Leonardo Can-bus went very very hot, until it smoked... I have replaced it, a nightmare to change, and the other goes hot as well.
For testing it, I just plugged CAN-L and CAN-H of the rectifier to the according pins on the Leonardo (and both talk togeher as shown previously) but it still get hot.
Maybe both should be connected with a common ground?

Is this the right thread for 2000W Flatpack2 HE programming as well? I am familiar with basics of C++/Arduino programming, but know very little about communication protocols. I can whip together libraries and expand on basic preliminary sketches though. I'm just trying to get up to speed on what people have already done, to see if I can reprogram my Flatpack 2000W HE that I scored off ebay for a project of mine.

Or is this thread only focused on the Flatpack S 1800W? I personally haven't been able to find many of them yet for aprice I can afford.
New to endless-sphere? Notice a lot of signatures recommending Ebikes.ca? That's because it's the best place for a quality and manageable, (but still 'real'), first build. Justin is a solid supporter of electric bike development, and a good source of equipment.
