Look fellas, I'm going through to many AA cells and it's time for a change. How are some of you putting 14500 cells to work in everyday items (radios,etc) without smoking the items?
Only after modding it completly, to cope with those voltages. About the only reason i even applied some of them, was after a cheap boost driver failed (regular batts), and it was easier to mod it to mostly direct drive. Or if you need higher voltages in smaller packages.
Like star halo said, time to get good rechargables in normal voltages.
Many of the lights where they can Jam in a 14500sized li-ion are using boost, and are not designed for the voltages either, but they are cool bright while it lasts

Way less lights are designed with some leeway for the higher voltage (some lights Are designed with the higher voltage in mind, most are just bleeding). So lots of the places they are used in lights, it is already pushing it over.
The AA sized Li-ion is not a miracle battery by any means, nothing like the 18650 li-ion which has a lot of capacity available. Because the 14500 arent ever great or robust, and long lasting, and because low self discharge AA ni-mh rechargables exists , there really is not very many reasons to use them :-(
Course if your just talking about 14500 Sized rechargables

well then AA low self discharge ni-mh is the way to go.
Potentially, a person could parellel them in where a 3x series set was used before (after a rewire), but there would have to be more reasons to do that, like to reduce weight, or for bragging rights, to use a certian driver, or something beyond just trying to get things to work.
Even for reduced weight, slightly higher voltage, and longer runtimes there is the lithium AA $$$ at the more normal voltages.
