Worst ever "fill up" since I started tracking it - 62.5 MPG(US) equivalent. Combination of very cold temps & recharging it before it was too drained.

In better news, on the advice of one of the EVDL Yodas, I bought another DC-DC converter off eBay, and it arrived yesterday. $26.50
It's the exact same VICOR model we already had, but it comes mounted on a circuit board with the needed bits and pieces to ensure we don't burn it out prematurely by hooking it up "raw" between the 48v pack & the 12v accessory battery.
I could have assembled the circuit components to do the same job as this little PCB, but this was just easier.
So... I may have the "naked" VICOR 48-12v DC DC for sale, if anyone's interested...
