NEW Hi-current Protected R123s

[Jim Watson]

AW, I have a Digilight NT9 furnished with batteries labeled:

"16340 Li-Ion Rechargeable Battery"
"3.7V 700 mAh with Re/Discharging with Control and Protection Circuit."

Is your battery this thread suitable?
In the Digilight charger which is labeled 8.4V 1A?

If not, what? Digilight is out of business.

[jumpstat]

BTW,

To AW and all celebrating Chinese New Year , 'Gong Xi Fa Chai' may this year be prosperous!!

[AW]

jumpstat : you 'll need a CC/CV charger for LiIon batteries. CC charging will only charge the battery to about 75-85% capacity and the CV phase will top off the battery.

Jim Watson : You can use my R123s in your NT9 but I don't suggest using the serial charger with 1A charging rate. The max. charge rate is 0.75A for these R123s.

When these cells are fully charged, what range is the peak voltage?

I have charged all 4 batteries and they measure around 4.17-4.18 volts using a Fluke MM.

[AW]

The fully charged voltage is 4.20V. Please note the charging is still going when the cell reaches 4.20V during the top off phase. Charge will terminate when current drops to < 3% of rated current.

[jumpstat]

Ah Yes, Thanks AW,

This is the information, that I was looking for.

As I look at it, the batteries are charged at a constant current, with varying voltage until it hits the preset voltage of 4.2v. Then charger will automatically reduce its current to allow the battery to be charged at the 4.2v level. Peak detection is max 3% charged current drop. Then trickle charging is subjected to the cells.

[Jim Watson]

Thanks, AW, guess I need still another charger.
How do I order?
I see posts here with orders and money by PayPal but how do I send you my address?
e-mail?

[AW]

Jim Watson,

Your shipping address will be send along in the PayPal payment from your record.

So i just want to confirm before I order: There is an actual PCB board inside the cell ensuring the cell does not over discharge and does not over charge?

[AW]

Yes, the PCB is attached to the bottom of the cell.

do u have apic of the protection circuit used in these cells please?
thanks

[AW]

It is using a pcb like this one :

[stockae92]

will 2 of these cells power up P91 or MN16 (M3T HOLA)? whats the run time will be like?

whats the difference in size compare to Surefire primary CR123A? will they be able to fit in a surefire spare carrier? (i need to think of a way to transport them)

[AW]

No, the max. continuous discharge rate is 1.5A. They'll fit inside the SF spare carrier.

I run the cells with KL1 head, when it reaches the lower protection voltage, the circuits will just cut off and KL1 will just stop. If you take a mm and check the battery, it will register 0.00 volts. After a finite time, the pcb shall restore connection.

Whilst charging, when it reaches the high protection voltage, 4.35V (i think) what will happen is that the circuit shall kick in to protect the battery. Same like above, after a finite time it will restore.

I use a standard rc charger which is the tekin 112A dc. But I can only use the direct timed charge. 65 minutes @500ma then 120 minutes @125ma. The reason I have to do it twice because at >500ma charge rate, my tekin shall shutdown because Voltage goes over 4.35v and protection kicks in.

I have charged about 3 cycles (4 batteries) and measured the peak voltage around 4.21 -4.24 lowest was 4.18 and so far the cells are holding up.

Hope the above helps....

I have a question for people using the Maha MH-C777 Plus II: is anybody having trouble going through a complete charge with these batteries? I've tried all of 4 of the cells I have and they all behaved the same.
It probably has something to do with the overcharge protection circuitry too, but whenever they get close to completing the charge, going for peak charge topping-off and reach about 4.1, 4.2V the charger just resets with beeping sound like the battery's being unplugged, maybe for 1 or 2 secs, then beeps again to indicate charging is being restarted, but then voltage reads 4.0V, even lower on 1 of the 4 cells, at 3.8V.
This cycle loops for quite a while, and they never seem to complete a full charge. Maybe I haven't left them long enough, but I called it quits after an entire day and not seeing any improvement... The older 750mAh RCR123a charges fine in about 2-3 hours depending on the level of depletion (Maha is a good but sloooow charger!).

I'd really appreciate any insight on this, since I've used my Maha for as long as I started using Li-Ions, a few years back now, and it never gave me problems before this...

Thanks!

Hello Jumpstat,

You are aware that overcharging Li-Ion cells beyond 4.200 volts greatly reduces the cycles you get from them, aren't you?

You should be able to find a proper charger that fits within your budget, if not, you should not be using these cells.

The protection circuit is a last fail safe to keep the cell from rapidly venting with flame if the charger malfunctions. I have had protection circuits fail before. It is not common, but it does happen. If your protection circuit fails, you will be in for an explosive surprise.

There are warnings everywhere that you should not use a charger designed for NiCd or NiMh cells with Li-Ion cells. In addition, the same warning is also stated from every battery manufacturer, and the battery manufacturers expect you to have protection circuits in everything.

If you are using Li-Ion cells, make sure you charge them on a charger designed to charge Li-Ion cells.

*Sigh*

Okay, the "Search This Thread" function, like the regular search function, barfs on "M1." Does anyone know if two of these cells will overdrive a Lumapower M1? Thanks.

[AW]

jumpstat,

Please take Tom's advice for safety sake.

New to my product line is these safety features rich Protected R123s.

New features :

- High Current Threshold : they are good to run on high current draw incan lamps such as P90, TL-3, Strion and CA1499. They 'll even power up the Lumens Factory HO-9 ( 320 lumens ) and EO-9 ( 380 lumens ) on just 1 click ( use on EO-9 is not recommended ).

Three of these cells wouldn't blow out the EO-9?
-Winston

[AW]

They certainly will blow the EO-9 which is a 9V lamp.

[winston]

They certainly will blow the EO-9 which is a 9V lamp.

But two will safely power it up, right? It'll be a little less bright than it would be on three primaries, but still brighter than the blown bulb from my last post. And on only one click?

Want to order 4 of these protected 123's and a charger, but need to know.

What kind of runtime will I be looking at in a SF C2 with this Malkoff P60 Cree.

"The input voltage is 3.8 - 9 volts. Below 3.8 volts it will drop out of regulation and run direct drive. The output is set at 1000ma or 180+ lumens. The draw is only 700ma, with 1000ma output at 6 volts. The runtime is 2-3 hours on 2 CR123 primary batteries."

Also need a price quote with registered shipping for:

4: Protected R123A ( 750 mAH ) ----- $ 6.00 each

1: This UltraFire LiIon intelligent charger ( model WF-139 ) $15

1: Optional 12V car cord $2.00

Can either TL-3 or H1499 run on 3 Li-ions - or will they just go "poof"?

[AW]

Both lamps can only run on two LiIons.

[tibim]

Wondering if these are the best choice to run in a SF M6 with the new Lumens Factory HOM6 Module as seen in this thread: http://www.candlepowerforums.com/vb/...d.php?t=170013

The concern is if it will fit in the M6 battery holder.

Also the link to your "order the batteries here" in the first post does not work... Do we just order in the "AW's LiIon Batteries Sales Thread *Part3*" thread?

-tibim

[robo21]

Is the WF-139 charger still in stock? I need some batteries and a charger.

Thanks

AW i received my batteries today. The exterior has not bumps like my tenergy RCR123 cells and they fit my Olight T20 with ease. These batteries are by far the best i have ever had! Awesome product AW keep it up.

[max52]

Tibin
The AW cells fit well in the M6. Now that I have the new Lumens Factory lamp, I use It more often. It has a much whiter tint.
Fenix-store.com has them-Use CPF8 for 8% off. LightHound also markets them. As Fenix-store states "they are all the same cell.

While this protected R123 physically fit and work in the Muyshondt Nautilus?
