rechargables for WE M100x?

[Bushman5]

is a 18650 rechargeable battery the same thing as as a LRB-168A Rechargeable Li-ion Battery ??? I cant find any info on theLRB-168ARechargeableLi-ionBattery anywhere but on the PTS website.....

i have the WE M100x, and want to convert to rechargables. How many do i need ? will they work with the (seemingly rare) M100x 12V bulb?

and where can i buy them? (Pacific Tactical Solutions can't ship batteries north to Canada)..

Yes, the Wolf Eyes LRB-168A is an 18650 cell. I suggest you order from AW - his protected Li-Ion cells are the best. His service is quick and efficient, and he ships worldwide.

You will need 2x 18650 cells for your M100. You will also need a 9v LA, which PTS can supply.

wow! that was fast! thanks DM51!!!

And just to confirm, i should be using "protected' cells, yes?

 

[DM51]

Yes - always use protected cells where possible, although there are some exceptions. Some hotwires need unprotected cells to fire up, and at the other end of the scale 10xxx size Li-Ions (AAA and smaller) don't have protection because there isn't a small enough circuit made to fit them.

When you get your 9v LA, do not use it with primaries (4x CR123As). If you ever decide to swap back from rechargeables, make sure to use the 12v LA, as a 12v supply would blow the 9v one.

Another question, say i had 4 3V RCR123's (when charged they are around 3.6V) ....what would happen if i bled off the batteries with a outside lamp, and once the voltage was down to say, 2.99V per battery (around 12V for all 4) , pop them into the flashlight and use them with the stock 12V bulb? seems to me if the voltage was bled off a bit to just under 12V, it would'nt insta

- and has anyone slightly overdriven the stock 12 volt bulb and what voltage did it blow at?

 

[DM51]

They are 4.2v when fully charged, so 4 of them would be 16.8v! They sag ~0.5v under load, depending on the load, which is where the 3.7v or 3.6v comes from.

The voltage of Li-Ion cells has a direct linear relationship with their state of charge, unlike other chemistries, but one must differentiate between voltage under load and "resting" voltage (resting is the voltage to which the cell bounces back after a couple of mins off the load.)

At 3.5v resting, they are effectively empty. Below 3.0v resting, they have been over-discharged and are damaged, possibly beyond recovery.

From this you will see it is NOT a good idea to discharge them to 2.99v to give you 12v!

:bow: you sir, and CPF are a wealth of info..thank you.

+1 AW 18650

Ultrafire makes less expensive 18650's. Some of mine require 2 clicks or more to run high current lamps.

 

[DM51]

Ultrafire 18650s are unreliable - see SilverFox's thread about this. There have been issues with their R123s as well.

Go with the LRB-168A's if you can afford them.
Failing that go with AW's, his are excellent and his service is A1++
