Unprotected mod batteries?

Says.. The recommended battery for the Mini REO is the AW IMR 14500. This is a safe chemistry, unprotected battery. Do not use other unprotected batteries.

Yet the sticky I cant find at the moment says not to.. Whats correct? I just ordered these.
AW 14500 IMR Rechargeable Battery - Batteries & Chargers - OVEREADY Flashlights/Torches - Control The Dark

Whats the risk when using these?

That kinda concerned me also....until I read this...

Li-Mn or Li-FePo4 rechargeables made by for example AW are a safe technology battery that can be used - they need no protection. They may not fit in your mod, check with the maker.


It's from this post....

Thanks for point that out. Yup thats the post..

I was confused about those batteries too, but thankfully found a post before I ordered. There's a guy here who is specializing in them: http://www.e-cigarette-forum.com/fo...ies-ultrafire-chargers-more-rtdvapor-com.html

Thanks.

The Pila charger is tops though..

I'm not really a battery expert but, as I understand it, the protected batterie have a circuit in them that will keep them from discharging dangerously or overcharging dangerously. The safe chemistry batteries, like the AW IMRs, can get to a venting situation but, if they do, they won't do anything extra spectacular like starting a fire or blowing your hand off. Just don't put them in anything that's air tight. If you know this is inaccurate, please post and correct me.

A lot of people have good results with AW IMR batteries.

ECF's current position is that unprotected safe chemistry batteries are the SAFEST option for mods because it is always possible for the protection circuit in lithium batteries to fail.

If you do buy protected batteries make sure to buy them from reliable manufacturers...this is not the place to save money with "no name" brands from eBay.

Basically this is correct. Standard Li-ion cells are volatile and vulnerable to overcharge, over-discharge, and in some cases impact damage. Other types of battery chemistry aren't. Because of their susceptibility to various issues, only protected Li-ion cells should be used. Others don't need the protection circuitry because, outside of severe abuse, they don't degas violently, ie blow up if in a confined space.

All mods with all batteries need gas vents, a sealed mod is a bad idea no matter what cells are used.

All batteries ideally need you to occasionally check the full charge voltage and the max discharge voltage, to check they are not being abused. For example you can get a 'safe' Li-FePo4 cell to fail if you put it in a standard charger, they need a different one as they charge at a lower voltage.

If you have a mod, you should have a small digital multimeter, it can be regarded as part of the kit. For $10 you get peace of mind, and a very useful tool for fault-finding.

Thanks for the info.

I have several digital multi-meters I picked up for around $3.00 a piece at a Harbor Freight sidewalk sale. Maybe I should put them up in classifieds.
