I am currently using 2x2s turnigy 5000mah 40c they work fine but they get pretty warm, warmer than I have had on any of my other boats plus I'm using ec5 connectors and they get quite warm. The ecs is barely warm to the touch though so I was wondering what c rating everyone is using? I have some 25c 5800mah 2s batteries that I would like to use but I'm not sure they would hold up.
