Double fenix pd30

[dmoose]

Hey new to the flashlight world

I had an idea what if i added an extra body inline to my fenix pd30 to allow 2 more batteries...

would this work or go kaboom ?

Ive looked around and cant find the technical info that would help me answer this maybe one of you know

thanks

The driver would fry from the extra voltage, unless you bored both bodies out to use (I'm assuming, here) the 4 CR123's in a 2serial2parallel arrangement. That would provide the same voltage, but significantly longer runtimes.

I heard about the good old Fenix T1's driver: it was capable of taking 16 Volts of input voltage, if I recall it correctly. I would not be too sure about saying that the PD30 will go then...

If you put 2x17670 instead of 4xCR123, it would be within range.

I think the driver would go poof with more than 6volts. Fenix's don't even like li-ion. Also, Fichtenelch, the driver in the PD30 is different than the one in the T1. So while the driver in the T1 "may" support 16 volts, I'm 99.999% sure you'll damage the driver in the PD30, even at 7.2v (nominal voltage).

PD30 works fine with fully charged 2x RCR123 (8,4V).

Do all the modes work? I've read many reports that most of the Fenix lineup lose modes with Li-ion, and even using li primary AA's in my LD20 can cause the loss of the low mode.

 

[LightChaser]

Since it uses a buck circuit, I'm assuming all the low modes will be available as long as you stay within the voltage limits of the driver. I believe the other lights (LD10, LD20, PD20) use boost circuits, and that's why you lose the low modes when using Li-Ion's in them.

Somebody please correct me if I'm wrong.

All my PD30's Q5 ; R2 and R4 have no problems at all with RCR123A Tenergy rechargeables batteries. Fully charged batteries give 4.2 Volts each = 8.4 Volts for two... All my tests always done at turbo mode.

I ran my P3D with Q5 Emitter flawless with 2xRCR123...didn't go yet...but i don't use it a lot.

Has anyone asked Fenix about this yet? They might give us more information...

Here's a 4sevens thread on running 3 RCR123 behing a P3D head. I've read somewhere that 4sevens tried 16V with a P3D and it didn't fry. That is not to say that it won't.

I do have all three of them... PD30 Q5, R2 and R4 and on the instruction booklet coming with all these superb flashlights there is no warning at all for not using RCR123A nor on the official site neither on an official Fenix Dealer site in Canada selling a Tenergy charger for all the Fenix Premium LED Torch. That is why I did not contact Fenix to ask them.

See what warning I do have with my TENERGY 4 Pack RCR123A 3V 900mAh Rechargeable Li-Ion Battery with Smart Charger :

Compatability/Suitability:​

• For SureFire and other brands of incandescent (halogen, kyrpton, xenon, etc.) flashlights which have a bulb rated 7.2V and under we do not recommend this setup. We typically do NOT recommend these for any incandescent flashlights. They work GREAT for most LED flashlights!

I hope my small input will help!​

To complete my last post, see what I found on a canadian web site selling mostly Fenix led torch :

Yes, that is clear...but I meant running not only 2, but more RCRs.

Anyways, your posts are helpful for some users for sure :thumbsup:
