Yes, for everything except chains and EC.

Once you make it to your one-cube limit, keep running that level using only your hourly energon. You will (slowly) recover BC via hourly recharges and level recharges (if applicable). If you don't throw nets at anything, you will always be up nets.

As an example, this episode I am farming H10. While I have lost about 35 EC (most of them spent getting to H10 because I'm impatient), I'm up around 200 BC and 200 nets (I didn't throw nets until H10 at Slag, who returns one for defeat, and Bumblebee, who returns 3 BC for capture).
