Hello,
I am selling my 3x Eltek high voltage Flatpacks in working order. These units are programmable and would work well for a Zero motorcycle or similar pack voltage vehicle. Two are the 16A and one is the 20A They rarely come up for sale.
$300 each for the 16A plus shipping from Sacramento, CA. $350 for the 20A. I can point you to the thread for programming and provide some Arduino code. I no longer have the PCBs for the units as I unfortunately accidentally gave them away
-_-
