The Fenix line is no, it is meant for 3v CR123A batteries only.
The CPF generally accepted line is yes, it can take it no problem, but it is driving it hard, and you will lose the lower levels.
Hi,
has anyone run his PD1 or P2D (PD20) on a LiPo for a couple of charges?

I've run my P1D CE and P2D on RCRs with no problems.
I've EDC'd a P1D CE for over 3 years.
On my keys, it ALMOST negates the need for my belt carried, (in AW holster from Lighthound), Nitecore Extreme.
interesting...this is the first non-anecdotal evidence ive read that rcr is safe...High is not going to be any brighter with an RCR123 than with a CR123. The other two modes will be the same brightness initially untill the voltage on the RCR123 starts to drop.
I don't think it is being driven harder with the RCR123 because my MM shows .7A on high. With the CR123 it shows 1.15A.
I've noticed this with my other Fenixes also. When a 4V battery is used there is less draw on it.
