No. Get the AW IMR 14500 for a REO Mini.

They (Trustfire) will "work" (ie: fire the atomizer), but not well and possibly not safely. From the ECF battery thread http://www.e-cigarette-forum.com/forum/ecf-library/129569-rechargeable-batteries.html:

14500 battery - 3.6 v
4.2 volts off charge, 3.6 volts in use, 3 volts minimum
14mm x 50mm (AA size)
THIS IS THE SMALLEST CELL THOUGHT TO BE SUITABLE FOR USE IN A MOD. Cells smaller than this simply do not have a high enough C rating. Not all cells of this size will have sufficient power, only AW Li-Mn [AW IMR 14500's] cells are known to be safe at this size, others may be but this cannot be stated as fact.


Come by the REO Forum Reos Mods There are usually people ready and willing to help out :)

I've used TrustFire Blue protected Li-ion batteries for a couple of years and never had a problem with them. However, the physical size of all protected Li-ion batteries will vary by brand. This is especially true for battery length which can vary by a couple of millimeters by brand. If a manufacturer recommends a particular brand they may have a good reason to do so. If they don't I use whatever makes good sense to me, like TrustFire protected blues. AW makes excellent batteries but for my purposes any good protected Li-ion is good enough.

The reason is more than safety. The AW IMR batteries do not drop off in performance as quickly as the trustfires. Also they are the only batteries in that size that can effectively power a LR atomizer or cartomizer.

Also from http://www.e-cigarette-forum.com/forum/ecf-library/129569-rechargeable-batteries.html :

Power rating for rechargeables

The critical factor for ecig mod use is the C rating (discharge current) in amps. The minimum possible value for safe and effective ecig use is 1 amp (= 1000mA) although ideally it needs to be higher. The ideal rating is 2 amps (2000mA) or better as an atomizer usually draws 1A to 2A.

Chart of C ratings vs size
1C or less for low-quality Li-FePo4
Assume 1C for generic Li-ion unless otherwise noted
1.5C for ultra/sure/trust/-fire Li-ion
2C for AW ICR (Li-ion)
3C for BDL 10440 IMR (Li-Mn)
5C for BDL 14500 IMR (Li-Mn)
8C for AW 14500 and 16340 IMR (Li-Mn)
10C for AW 18650 IMR (Li-Mn)
10C for AW Li-FePo4

Note:
Tenergy etc Li-FePo4 (small cells) - <0.55A (~1C - half an amp or less - not suitable for ecig use)

Max drain rate in amps is C in mAh / 1000 x C rating
Example: an AW IMR Li-Mn 14500 battery has a capacity of 600mAh. The C rating is 8C (it can supply 8 times the capacity). Therefore the max discharge current in amps is:
600 x 8 over 1000 (600 multiplied by 8 divided by 1000)
= 4800 / 1000
= 4.8 amps
This shows it has enough beef to safely and effectively run an atomizer - which some 14500's don't. In other words it is less likely to go into thermal runaway if there is an internal fault in the battery and is then used to power a device that draws a relatively high current such as an atomizer; and it will not suffer from excessive voltage drop when powering the atty.


In general, the AW IMR 14500 will last for about 4 hours. It is easy to change them in a REO.

14500 TrustFire Protected Blues have 900 mAh stamped on the battery. I take amp/hr ratings on any far-eastern made batteries with a grain of salt :facepalm: but I find the TrustFire Blues to be very good performers.

True, but LR attys are a very different use than a laser pointer. I am being a broken record here, but anyone using rechargeable batteries in their hand and next to their face should read http://www.e-cigarette-forum.com/forum/ecf-library/129569-rechargeable-batteries.html

I understand your point, however it's a virtual given that any Li-ion battery that's going to blow is going to give you some warning signs first: like getting really really hot, smelling bad or producing acrid smoke. Most users may take this a warning sign and refrain from putting said appliance in close proximity to the face.

I don't scare easy and understand the FUD (fear, uncertainty and doubt) marketing concept.

No FUD marketing. In this application, the AW IMR 14500 is a safer battery, it works better, and it is recommended by the mod maker. It's not like other people haven't been chasing false mAh ratings and been disappointed by the ***fire battery performance.

If the AW is recommended by the manufacturer, then that's the way to go. They have the tight tolerances of the AW in mind.

My 250 mW (1/4 watt output) laser pointer pulls 380mA and has a substantial heat sink to keep the electronics from frying. It's not like powering a heating element on a PV, but it's no slouch regarding power draw.
