I'm going to be acquiring a laser soon that requires this battery... does anyone have a preferred source (DX and similar sites are a last resort :p) for these?

If you have some to sell, drop me a line too I guess.

these AW batteries seems to be verry good quality, found here:Li-Ion Protected Batteries

Otherwise yea just DX for ultrafire / trustfire / or WhateverFire batteries ive used trustfire batteries for a while now seems to be ok most are under spec but still good to go for the money

For charger the dsd charger seems verry good been using it for over just a year now http://www.dealextreme.com/details.dx/sku.936

Okay, thanks for the reply (+1).

Also, with protected vs. unprotected batteries, will I just need to time how long they've (unprotected) been charging and take them out at the appropriate time?

Well with unprotected cells you should check them up once in a while when you use them just to make sure they dont go below the min. Voltage, while charging you dont have to worry those chargers stop @ 4,2V if its working alright.....:undecided: mine stops @ 4,12V so it should be ok i stil rather use protected cells though even if they are just slightly larger then unprotected

Trevor;

I have quite a few for sale with chargers.

They are new 2400 mah Panasonic cells which have gone thru U.L. testing.

They are considered "unprotected" by forum members although I trust the test labs more.

More info in Link below.

I just ordered a 18650 cell from larry, it arrived in 2 days:)

As far as unprotected cells go, you don't really need to worry. At least about them draining below the 2.5v minimum. Any green laser that is using a 4.2v power source is going to quit long before you reach 2.5v.
Likewise if it's for a red or blu-ray build, more then likely it would be using a Dr. lava flex drive. Again your laser will cut out ,long before it hits 2.5v.

As far as safety goes. I would trust a unprotected panasonic or sanyo cell, over a protected DX trust fire, any day.

Also keep in mind protected batteries will always be bigger in diameter, and length. I have 3 lasers, two manufactured and one custom. All three wont accept a protected 18650 cell because of size.
