Default Li-ion alternative for a 3-triple-A pack

Hi, I have a host I'm planning to use but it uses a 3 triple A battery pack.
An 18650 is longer than this pack and smaller in diameter. What's a good Li-ion to replace this triple A pack with so I can get more power..

thanks

The dimensions of the battery pack would be a big help.. Is your 18650 protected?

There are some C-size Li-Ion 22500 or 25500 Li-Ion.. Would hve to remove extra spring length though they are 6mm longer

I have a three AAA holder for a flashlight right here. Mine is 21mm dia. by 51mm long. A 25500 may be too fat for your host, my 3 x AAA fits a host with a 23.5mm dia. battery tube. An 18350 with a long battery spring or some magnets might do. An 18650 is too long, at least for the host that my 3 x AAA holder fits. Measure your host carefully.

18500 battery length is exactly what you need. I took the 3aaa holder out of my guidesman and this 18500 length is a perfect match

If running a high voltage works for your driver you can just use 3 - 10440's in the AAA pack and not worry about spacers or anything.

Could also use 1 x 10440 in the three pack, and two bridge wires in the empty spots. That's if a 10440 will deliver enough current for your application. The 18500 suggested above sounds really good.

Default Re: Li-ion alternative for a 3-triple-A pack

Depends on your voltage and current needs;

One of these 18500's will work well for driving a 445nm with a high current boost driver.

Or you could use 3 10440's in the stock battery holder, with a buck driver.

Building off of that idea, and hoping that jme is still watching this thread. Rewire the stock 3-pack so that it puts three 10440's in parallel. That'll get you the 4.2-2.5 volts you want, decent capacity, and you still get to use the stock parts.
