My motorcycle (honda CBF150) came with a 12V 3AH battery. I want to change the stock 35w headlight to a higher power one and connect them directly to the battery (the stock ones are not, and they fluctuate). I also want to add fog lights and usb chargers in the future. To do that, I'm thinking maybe I need to increase the battery capacity.
Will replacing the current battery with a 7AH battery be enough or will I have to change the whole system (rectifier and all).
