Adding a cap

[mwe-maxxowner]

I have two blown novak HV maxx escs. I would like to remove one of the caps and install it on my mamba max (not pro) esc. I just installed an external bec to help keep temps down. I have read caps can help too. Seems pretty straightforward to me.

I just want to make sure, is there anything special I should know? Such as solder the cap wires near the esc or the battery plug? Or anything else?

Thanks guys.
