18500 adapter?

Loganberry · 12-01-2015, 07:58 PM

I have a few lithium imr 18500 batteries - almost the same size as AA, 3.7 Volts. Is there an adapter so that I could use these?

If you're handy with a soldering gun, you might be able to get a battery adapter from ebay/amazon and cannibalize it a little bit. With 2 cells in series, you have a battery with 7.4v which is the nominal voltage of the d-li109 battery. Wire two series in parallel (4 total batteries) and you've got a 7.4v battery whose capacity is twice that of a the rating for a single cell (i.e. 2x750mAh or whatever). A costly way to do it, if you ask me; the 14500 cells aren't cheap.
