I use one of the hitec x4 chargers so I balance charge both batteries after each run. Is there a better way for me to charge my batteries? I use 2 gens ace hard pack 40c 5000's for qualifiers and 2 Orion carbon pro 90c 5000's for my main. I'm wondering if there could be something in my esc that's making it happen? Some kind of setting I have wrong?
