I have an project where I am lighting up 3 6v 0.3 amp small lights from a double 9v battery pack wired in series. Although it works fine, the batteries are getting hot very quickly. I’m new at hobby electronics and have read several article in this simple wiring but no mentions of the controlling the heat. I thought the electricity flow would not cause this intense build up of heat and I’m not sure what to do to prevent it. Any pointers to something that will help me understand what’s happening with this simple circuit and preventing the battery heat build up would be appreciated.
Cheers,
Ed
