So if you have an original capacitor value such as 16v 500uf one can use a 16V 1000uf. I bring up this up because capacitors really only cost a few cents versus $3.50 or higher from various speed control manufacturers.
For capacitor replacements on Novak controllers, we recommend only our TransCap modules. They can be used as replacement caps on all racing controllers, brush or brushless. (see various lipo versions) We consider these modules an intrinsic part of our esc design; they are are not only capacitors, but also include two Transient Suppressors and three High Frequency Decoupling Capacitors:
