All these machines charging system generally can't keep up once you add the extra draw like the things you have which is typical. Get in the habit of connecting a good trickle or smart charger when you are not riding to have your battery fully charged each time you head out. Many upgrade to a larger battery or various dual battery setups. That will help if but you can't keep up you charging needs now you still won't with dual batteries, it will just take longer to draw them down. If you use an isolator with duals you can keep your starting battery hot all the time and just use the aux battery for the add on acc. Regardless for optimum performance connecting a charger when done riding is a must IMO. There are some upgraded charging systems but the ones I have seen are expensive and require a belt and hole in you belt/clutch cover. They are not popular for those reasons.
