I have a 12” LED light bar and two LED fog lights that that are seldom used (I don’t do much night riding). And soon will be installing some kind of basic sound system or sound bar that will be used about half the time I am riding in my buggy. That will probably be the only electrical accessories that I ever install on my buggy. Questions...is the P500’s charging system up to the task and also, do I need a dual battery set up ? I don’t mind going to dual batteries if needed but don’t want to go through the trouble/expense if it is not necessary.
