Wayne,
I'd like to get a shark setup with a max output of 300 ma and the pot removed for an external pot. Is this possible and how much would it be? Also, could you please point me in the direction of a pot suitable for mounting in a Mag? Thanks in advance.

The sense resistor used on the Shark and many other boards follows the resistor values according to the E12 range.
See this chart (yellow column)
here.
The closest value would be 0.33 and I have those if you want them swapped.
Since I have not seen this request very often I will do this for you for free. If you order the Shark and select the remove trim pot option and then in the order notes put the request to change the sense resistor to 0.33 I can change the sense resistor at the same time I remove the trim pot.
I would really recommend others should reduce the sense resistor for maximum current of 750mA on the current shark as it extends the battery range options and makes the Shark thermal management easier.
There are a lot of pots out there to choose from and I have not suggested any one of them since I have not looked among the many out there to recommend any one in particular. I use digikey or mouser for many of my parts and mouser.
If anyone has a pot they have used and would like to recommend or share it that would be great.
Wayne
