Is anyone using rechargeable batteries in the Eznite and if so are you using three 3.0 or 3.6 volt with a dummy or four 3.0 volt?

Thanks

Chris
 
Yes, using the Tenergy 900 mah 3.0 V - 3 of them and a dummy. Got them from Battery Junction. I believe off the charger, they measure 3.3 V or so. I let them rest a bit. Although, I believe Patriot36 is using 4 of them with no issues. Not sure I'm brave enough to do that.

You can use 3 regular Li-Ions no problemo. Using 3x 3.0v cells you are underdriving the ballast which is also bad for it.

I've been using the 4 X 3.0 volt Tenergy batteries but have very little time using this setup. So far (only about an hour or so total time) no problems....

Hmmm...ok, I'm convinced. I'll use 4 of the Tenergy's. That would probably change the shootout 4 results btw the Mac's Mini and my EZnite.
 
Thanks for the information. I think for now I will just use primary batteries.
 
WOW! I'm much more impressed now with the 4 RCR123's. Warm-up time is much less and the color temp has come down noticeably. Definitely need to have a re-match against AdamLau's Mac Mini again. Shame on me - a flashaholic who loves to overdrive for not getting this right a long time ago.
 
Patriot36 told me to run the Tenergys and I was a bit chicken initially but that's what I use now. You can sure see the difference.

That explains the performance issues.... :kiss:



I'm glad to hear that you're happy with it now. I drained a set of RCR123's through mine this weekend while hiking in the woods. I'm always please with that little light.
 
I see that Batt Junc now has 1000 mAh batteries in stock. I can assume that they will work as well. My Jil EZNite is in route and need to order some batteries. Are these Tenergy decent for the price?

THanks,

What voltage do the Tenergy 3.0v cells hold under a 1 amp load? You may be overdriving the ballast hard.

I'm very pleased with mine, too, though I haven't had the opportunity to use it very much yet. I have a set of rechargeable Tenergies on its way and look forward to te comparison.
The only problem I've run across is that I haven't got an allen key small enough for the collimating screws........ my smallest one is 2 mm. Does anyone know what size the screws take? I haven't neede to center the bulb but it irks me not to have the right tool for a job I may need to do.
The light is easily te best made of the few I have and a very convenient size, I find.
I forget who it was that steered me towards the Eznite, but whoever it was, I thank him!
 
Due to low Voltage readings, the Triton stops the 1 Amp rate discharge of a fully charged Tenergy 900 mah cell (4.1 V) after about 5 seconds but the Voltage reading while discharging reads 2.8V. What I don't understand is that I'm using the same light, same batts and same charger as Patriot36 and getting only 60% of his run time.
 
Sorry guys I guess I need to read the Large Print. I was looking at the "D" size Tenergy. Are you guys running four of the Tenery 3.0v 900mAh without any problems? I know that is overdriving them a bit.

Also, what charger is reccomended for these batteries?

Scott
 
Yes, Patriot36, Karlthev and I are running 4 of them with no issues except I am not getting the runtime that Pat36 is for some reason.

Get the specific Tenergy charger for them at Battery Junction. You can get a kit with charger and 4 cells on sale for IIRC $29 and change.
 
OK, measured the Amp draw consumed by my EZnite. Running Amps reflects immediately after the starting and warm-up cycle has concluded. It is a very obvious transition.

Starting Amps.............. .85 (immediate upon turn-on)
Running Amps............. 1.24 (after about 8 to 10 seconds)

Mac, is this in-line with the W/A 10 Watt Solarc performance you're used to?

I'd be interested what others are seeing? Any takers?

Just to clarify then, your cells are reading 2.8V under a 1 Amp load? If that's the case then I think this battery combination is fantastic.

It just occured to me Bob, that the run time you're getting is more in line with 3 x 3.7V RCR123/s + dummy cell than it is with 4 x 3.0V cells. That short run time was the only problem that I had with the mini-mini. I only got about 26-28 minutes with 3 freshly charged AW's.
 
Paul, I'm not really convinced the 1 Amp Triton discharge test was a valid test so i would not trust that number.

My EZnite Amp readings are from inserting my DMM in-series using its Ammeter function. Amateur tech at work, proceed below with caution.... Install your DMM leads into the DMM to read Amps. Set the DMM switches to read up to 2 Amps minimum. Carefully place the front half of the light onto a mouse pad to protect it. Carefully place the loaded battery carrier on top of the front half of the light where it normally sets when the light is assembled (positive contact of battery carrier sitting on brass positive contact of the red circuit board). The next step completes the electrical circuit and the light will turn on. (Remember, no light will be visible to you because you are protecting the front half of the light by having it face-down on the mouse pad). Firmly place one test lead onto back brass negative plate of battery carrier and the other onto the raw threads of the front half of the light. A second set of hands is useful but not necessary to steady the battery carrier (it wobbles a bit). Read Amps as it's starting and as it settles upward. Note my readings. .85 initial strike and 1.25 running warmed up.

OK, charged the batts again and did a Volt probe during start and run.

Starting Volts: 15.03
Turn on: 11.55
Steady run 10.4

10.4 Volts x's 1.25 Amps = 13 Watts

Hmmm.... Do I say that I've got the one and only SPECIAL 13 Watt EZnite? :nana:

Just throwing this out as a theory cause I don't really know. 10 to 13 Watts = a 30% increase. 40 min run time vrs 26 or 27 min. - a 30% reduction.

Mac, is the Solarc 10 Watt unit 10 Watts to the bulb or system Watts?

Maybe this is why my run time is low or maybe not, but I'm having lots of fun probing!
