These bikes can't hardly charge their own battery much less run any accessories. Thanks for info
Why do you say that? This bike has a plenty strong alternator and provides plenty of power. I've run with two people with heated gear and never had a bit of problem. Never had an issue with the battery except for connections coming loose. Replaced the battery after three years for just because... It was still running fine at the time. Never put a battery tender on it in the winter and never had a starting issue. Are you trying to power up a rail gun or something? If so, inquiring minds want to know.
Have you had problems with the charging system?
