HKJ has released a review of the ncrpf lately, it’s called orbtronic PD in his comparator.

RMM:
I’m sure that others will chime in, but here are my 2 cents:
-If you are looking for maximum output, go with an unprotected cell. All protected cells will increase resistance. The 20R will give you a slightly higher initial output, while the PF has a lot more capacity and will hold brightness longer. The PF so far has been slightly outperforming the PD it replaced.
-If you are more concerned with safety, especially when using cells in series, then protected is the only way to go. Both the protected cells I sell (Evva) and the KP cells use a quality Seiko IC and the same AO MOSFETs. The Evva Pana. 3400 has 3 MOSFETs vs. the 2 on the KP. What I do not know is if this will make any significant difference in resistance.
Can you please check to see if unprotected PF’s will make contact with each other in series (without magnets)?

They will, I have tested them. The button doesn't protrude much but it is enough to make solid contact as long as your spring can keep them together.
Nice, looks to have slightly more sag VS 20R at the start like RMM said.
As far as the increased resistance goes with protected, how much of a decrease am I looking at roughly? I know my generic NcrB 3400 protected DD just an emitter (Test bench setup) at around 5amps.
Should i be concerned about Direct driving 3x high draw batteries with the stock DRY driver (using 20R/PF)?
