If you start a thread with your questions here under the Normal threads section you will get lots of answers. Just go to the main forum and scroll down to the bottom!!!
Will these work for a few days til my good batts get shipped? Mini reno btw
Tenergy Battery 14500

Yes, they will work. When it comes to protected Li-Io batteries, I prefer these AW 14500 batteries but those will get the job done.

Its good know your battery lengths too......Props to Lazarrred
Which one is the right length? (65.18-66?)
The one being measured is the recommended battery. The others shown are longer, and might compress the spring too much and not allow it to drop the battery from the contact in case of a short.
This thread is amazing! Before reading, I was happy with my battery ignorance. I was happy knowing that the major difference between regular Trustfire type and the AW IMR was the war between "drop off times". But now I understand there's more to it. The AW IMR is a tad shorter than the TF which provides escape from the firing pin should a short ever happen.
I was content in my plans of using the TF's already in house until I could also afford the almighty AW and Pita expensive charger. But now I'm not sure if that would be okay. Would it be okay to use my good old TF until I can purchase the AW's?
Which length is best for the Grand?
haha, I bet you can't tell that I'm still a techno-phobic. watts, volts, ohms, rpms, currents,

Some people do use other batteries with no problems. Some all the time, and some just until they can buy the AW IMR's.
Is it o.k.? Well, I can't say that because they are not recommended. Will they work? Yes.
The AW IMR 18650 provide lots of room for the spring to collapse. The shorter the battery the better.

I have a Trustfire Flame 18650 3.7 Protected battery. I put it in my Grand to check the fit. It compresses the spring almost to the bottom. My AW IMR 18650 3.7 leaves plenty of expanded spring area to compress. Therefore I must say the fit of the AW IMR is much better. Just for safety. I can not say anything about other batteries because I do not have them in hand to compare.
The AW IMR 18650 is unprotected, because of it's chemistry, it doesn't need it. "Protection" is a PCB that is attached to the end of the battery, usually lengthening it by about 2mm. (Battery "numbers" denote their size, e.g., 18650 is *supposed* to be 18 mm X 65 mm [the 0 at the end means it's round])
Protection is supposed to kick in to prevent problems, but PCB's have been known to fail. Given that Rob was conscientious enough to design the REO around the AW IMR 18650 "safe chemistry", that's all I use. An extra hour or two of use, or saving a few bucks isn't worth making myself any uglier than I already am (see my avatar)
LiOn batteries can be quite nasty when they misbehave, and they are quite close to your face. The IMR's can, like the LiOn's, also go into rapid discharge under certain circumstances, but they generally don't do so with flames, like the LiOn's. Hundreds, maybe thousands use the LiOn with no problem, but personally, I think life is risky enough to not knowingly take any extra risks. Everyone has to judge for themselves what's an "acceptable" risk and what isn't.

Very good Bill! I think you covered this well!

Well, I'm certainly no battery expert, but I figure it this way. If I use a battery that's 68mm instead of 65mm, the spring has 3 *less* mm to compress and break the circuit. Longer run time (in a short circuit) means more damage, and I'd be devastated if anything happened to one of my REOs.
Like everyone else here, I do take risks, this just isn't one of them
Edited to correct STUPID above post, which was *completely* wrong

Yes, the AW IMR 18650 1600 mAh 3.7v @ 65 mm in length, the recommended battery for the Grand, is the best fit to allow function of the spring safety feature.
Sorry to sound dumb but what is the spring safety feature? I understand a battery can vent but what does that have to do with the spring?
If there is a short and the battery heats up, the spring holding the battery against the firing pin will collapse and break contact.
