I'm looking to sell my onyx 245 and get one of these ^^bad boys..my question is while I'm looking/waiting for the right power supply I could just use the 2 12v car batteries correct ?
That I'm not sure would work. Your taking a huge step up from the charger you have now. I've seen the supplies you need for 80+shipping on eBay for 2 12v 47amps. Already to go so you don't have to convert your self

It is SOOOO easy to convert power supplies... and CHEAP.
One of the last ones I did did not even require soldering to get 12v and 41a... for less than $15!!
I have even had members buy supplies shipped directly to me to have them converted and ready to go...
Whatever it is I just typed... could be wrong.
It occurs to me that this is actually third-party product support, but in general any DC charger can be powered by a 12V battery, and some by a 24V battery/ies.
