Tenergy 3.0v R123A

[Hallorann]

Can anyone tell me if these batteries are protected against overdischarge or not?

Usually protected cells include "Protected" in the product name, but these Tenergys do not. They do, however, list overdischarge protection in the description.

Only interested in Protected cells.


Thanks!

If you look carefully, you can find the part that says, "Full PCB protection against: Over-Discharge, Over-Charge, Short Circuit & Over-Current along with voltage regulation." This means they're protected against the most common Li-Ion problems. If you search for runtime graphs of lights with these cells, you'll see a nearly flat discharge curve, followed by a perfectly vertical drop when the overdischarge protection kicks in and cuts power. I don't know if it's too good for the cells to discharge them that much, but the protection should prevent the cells from becoming too damaged if you ever turn on a light and forget to turn it off. I EDC a pair of these cells in my Gladius, and they work fine.

if you are planning on using em to power an incan light, I suggest just switching to a 3.7V or 9V solution. the 3.0V li-ions are just voltage regulated 3.7V cells. They don't do well in heavy loads, and will usually prematurely fry lamps designed for 2 CR123s. If for some other application then pretend my post doesn't exist, lol.

I use them in incandescent lights such as a 3c with sleeve loaded with 3 R123s to overdrive K-12 6V lamps in the Mag. This lamp pulls low amps. so the tenergy has no problem. For high amp draw icandescent lamps that require 3 Volts, I use Powerizer 3 Volts. These are not protected except for venting at high temperature. The Powerizers can pull amps. I have the in my M6. There is a seperate charger for each battery. Don't get them mixed-up. The Powerizers work well, and provide the the proverbial "guilt-free" Lumens. They also slightly over-drive the lamps. They do require the most caution, particularly in packs. They need to checked often, and balanced with other powerizer cells if you plan to use then in packs. They do perform well and most people can see the difference when replacindg CR123as with Powerizer R123as.

Hey guys

Thanks for the replies! The application for these 3.0v R123s is twofold:



1) For use in a Streamlight TL-2 LED with SSC P4 emitter mod. I strongly prefer to use only rechargeables in all of my lights, so it looks like there are two options here - 1x18650 for a dimmer light and more runtime, and 2xR123 3.0v for a brighter light and less runtime. I am told that using two of my AW 3.7v R123s will be too much current for this light.

2) For use in my new AmiLite T5 after I replace its burned out emitter with an SSC P4



I am trying to decide between AW's LiFePO4 (NOT protected) 3.0v R123s and the Tenergy 3.0 (Protected) 3.0v R123s.

I have noticed that the LiFeP04s are 500mAh, and the Tenergys are 900mAh.

Which of these two cell types would be best for my two specific applications? Would the 900mAh be better than the 500mAh?


Thanks very much!

I think the Tenergy 900 mAh is quite exaggerated, and is probably (a guess) more in the 600mAh range. I like them because they are protected, fit in my P1DCE, and thus can be used with some degree of safety in a 2x3.0V configuration in the Lumapower M1 with low-high switch (3.7V x2 is too much for the low stage switch). e-lectronics.net also sells protected 3.0V 600mAh RCR123s, which seem to work ok as well, though some don't fit the P1DCE. I've not directly compared the two brands.

I have some of these, they don't have anywhere near 900mAh capacity,
closer to half that.
The LiFePO4's are about the same actual capacity for flashlight use.

The Powerizers have considerably more capacity, but no protection.

Order placed for Tenergy cells/Tenergy charger.

Decided that the Protected cells would be best.

Thanks
