With all respect, you guys are looking at numbers on spec sheets and marketing literature. I can tell you for certain that I, and many other members of this Forum, are routinely running, on the V650, all the equipment I mentioned (heated vest, heated gloves, GPS, extra lights, headlight modulator, etc) without any problem. I installed a led digital voltmeter that monitors the voltage level, and it never drops below 13.7 volts while running above 3000RPM. Varies between 13.9 and 14.1 volts; the drop caused by the headlight modulator. And, I'm still running the original OEM battery on my 09V, after over 20,000 miles.
BTW, I'm using a Gerber heated vest and heated gloves.
Several owners have had a problem with the rectifier/regulator after mileage is around/over 40,000 miles. But that's it.
