I don't care what they rate esc's at, if you put a 140 amp continuous load on your system you will have hot wires and melted solder joints. Along with a puffed lipo, actually you won't have a puffed lipo, The internal solder joints will melt first.
I never wanted to give the impression that these 120A or 160A numbers are entirely realistic, but even only 50% of these, is
so much more than most chargers can discharge with (certainly if only internally), just so the OP just shouldn't need to worry about that at all.
