Choice of current sensing reisistor
The "RN, RH" are wirewound with no hint about inductance, so depending on your use case, they might be unusable.

I can't open the link for http://www.topresistor.com/wp-content/uploads/2013/07/FL.pdf so it may be no use either.

I would have expected something like 50mΩ ±1.0% 7W SMD or 50mΩ 1% 5W through hole, designed to be low-inductance current shunts, which specify inductance. 

Maybe a lower resistance to reduce power loss.
