Best RCR123a for a Fenix P1 & Nuwai Q3

I've gone through about 5 pages in this forum & a couple in the "Batteries" . Now I'm more wary about who to order from & what to order.

In simple KISS form.
I'm looking for opinions on who to order (3.6v rechargeables, protected or unprotected) from & which model.

My criteria is:
Best mix between output & running time
&
Fitment
i.e. I was ready to order from one of the repected vendors on this site; but I noticed in the feedback that his new line was a bit too thick for quite a few flashlights.

I'd rather pay a couple bucks extra up front (if need be) oppossed to getting a cell that is too thick or long. Sometimes size does matter.

Thanks for your input.

LGCubana,

You should ask John at Lighthound.com. The Nuwai QIII should take protected RCR123.

Any one try AW's new generation LiFePO4 R123 with safe chemistry a Nuwaii Q3, Fenix P1?

Im using lighthound protected rcr123 750ma battery, gives me 55-57 min continous runtime in my P1, and I charge it it with a nano charger takes bout 2 hrs or less with a completly discharged battery and barely gets the batt warm during the charging.

Thanks for the input
