I pulled Eltek chargers from my car now. Interested? They work up to 420Vdc and are programmed for different addresses 0x300, 0x310 and 0x320. But they also work with 0x2FF command. Liquid cooled and easy to setup
I offer single charger for 600€ and 2x for 1000€.
I would offer all 3 but one is reserved for Johannes 
.
Some photos will follow...
