thats weird, if you managed to fry the ccbec, there is a chance you have fried the MMM bec in the exact same way, thats quite a coincidence, something must be wrong with your setup, like a short in wiring somewhere that you are not aware of may be. I've been running my V2 MMM flawlessly thru 6 packs so far with SportBec and fan wired to RX directly
