*Important Message*
As of 28/1/26 my CANnedIce V3 is currently out of stock, another batch is being ordered middle of February 2026
I do not want to remove the listing as I will be getting more as soon as possible, but please do not order until I can give a date when I can restock them
Hello.
I use these fantastic Eltek
FlatPack power supplies in my RC/UAV charge case builds and thanks to the
original guy that helped decode the Canbus data, I have been able to set the
voltage required.
The only problem has always been the need for Revision 3+ units ideally for me so that I can permanently set the output voltage and leave it at that, but now my electronics wizard has got involved again on something to compliment his excellent Eltek power PCB also available;
FlatPack item number;
Front End Power PCB; 194518608979
So I present to you the CANnedIce
V3 controller (first photo is of new V3 board design) which now features an ESP32, this gives us more room and
currently we can control Eltek FlatPack/Front End as well as Huawei rectifiers.
Others such as Vertiv will be added as time allows. With the addition of a separate power board this can control HP DPS common slot server supplies also for PSU failure protection when used with the RC/UAV iCharger DUO LiPo chargers.
We have on-board
Canbus controller, buck convert for up to 60 volts operation, I2C for the PCB
mounted OLED display (this can be remote wired if preferred) and some other I/O
pins we are going to expand with as time goes on. Currently we can use a strip
or 20 NeoPixel LED’s to provide status information.
We’ve also incorporated
the contactor control components all on the one PCB now.
The ESP32 provides WiFi connectivity and can work as an access point for direct
monitoring of the data coming out of the Eltek, or can be connected to your
WiFi network for more remote monitoring.
The designer has built in OTA
updateability which is handy to meaning once granted access to your CANnedIce’s
web address we can push updates if made.
Using the web interface the user can set a voltage output value, which is then
updated regularly for pre-rev 3 units so it stays constant, but if the Eltek
allows (Rev3+), the set voltage can be stored permanently.
You can use the Serial monitor within Arduino which shows more data also, but
this now requires a separate CH340 adaptor and special lead as we removed the
USB port to put the contactor components on the one PCB.
I have made a YouTube video of
the original V1 controller in action, the V2 operates very much the same;

This V3 batch will just include the main PCB with OLED display fitted and snap off temperature sensor, leaving the customer to order any wiring and connectors themselves. Or I can provide these at extra cost when connecting to one of my power PCB's.
Also please note details above
are liable to change as I perhaps find better ways to explain the features of
this device and if we add more functionality via firmware changes.
I have put a longer dispatch time
to aid myself if I need to order more OLED display etc as these sell, but will
always endeavour to get your purchase out the door as quickly as possible.
