3.0 Li-ion rechargables.

[Kraid]

Are 3.0 V Li-ion rechargables a good option for Fenix lights? I've heard that the 3.6 V rechargables cause you to lose the low modes.

That's right, 3.7v RCR123's do cause you to lose low levels. I have usd 3.0v RCR123's I got from the Source in my L1T with CR123 body. They work well enough but the runtime is not that great.

If you are using 3.0V RCR123as, you cannot use the standard type of Li-ion charger which charges to 4.2V. You must get a specific charger that terminates at 3.6V (I think).

That all has me reconsidering buying a single-cell Fenix CR123 light.

Depends on the cell. 3.0v LiFePO4 cells need a special charger.

However, they make 3.7v Li-Ion cells which have a special protection circuit with reduces the voltage to 3.0v after approximately 12 milliseconds under load. This will instaflash incan bulbs, the the Fenix P1D/P2D work just fine with them, keeping all modes. They also use a standard Li-Ion charger.

I think some of them use different chargers. 4.4v in a few cases, rather than the 4.2v with the "regular" RCR123s.

yea to overcome the voltage dropping device in the cell, they usually require 4.4V charging to actually bring the cell up to 4.2. But keep in mind not all 3.0V cells are this way, a LiFeP04 cell with the same type of circuit in it, will require about a 3.8V charging voltage, (instead of a bare cells ~3.6V requirement)

What cells are these? They don't have the reduced capacity of LifePo4s? And I can use them in my BatteryStation Charger?

I know Tenergy make some, not sure all who else.

Tenergy makes some 900 MaH 3.0 volt Li-Ion's. I use them in my Insight Typhoon (Gladius) and in my SF C2 with a BOG Q5 drop-in. I've done a runtime test in the Typhoon and got a 1 hr and 15 minutes before the light started blinking ( indicating the batteries needed changing). Hope this helps.

Thanks all!

Ok, how about using these on a Wolf-Eyes 3.7V-6V Q5? Will this damage the module?

I use 3.7v AW RCR123A on my Fenix P3D Q5 and I did not lose the low modes.

Which Fenix lights lose low modes using 3.7v?

Same here but my lowest mode are really low, but i enjoy my low low.

The P1D, P2D, L1D, L2D

It's useful to note that the P2D, L1D, and L2D all use the same head, meaning they will all take ~.9v-3.3v without issue. Ever notice that the brightness levels in the general modes are identical for all 3 of them, and only the brightness in turbo, and all the runtimes are different?
