OH, you certainly know more about li-po than I do! I didn't notice that was what he was asking about. However, I have, all my life, thought you could run any set of batteries parallel to increase amp's available along with increased 'gas'. I have been wrong many times in my life before! No reason not to be now!!

Are you using a li-po compatable ESC? If so, they are designed to shut off before the voltage gets too low to prevent damage. Regular ESC's do not shut off soon enough. You may very well know what you are doing and I don't mean to suggest otherwise, just that you mentioned the inadvertant safety feature of your ESC.[8D]

I'll leave well enough alone and see you later!
