My esc will handle 5s, can i run a 2s and 3s in series? Or is that a no no to mix cell count batteries? They are same brand, both 5200mah and 50c .Thanks

yes. but you better check battery that is closest to negative esc wire .that will give to most milliamps to esc it will have less voltage when done a simple battery buzzer can help you.
