ALSO: I was reading up on laser units, you could rig one to a CR2032 battery, which is really flat. If you got a 6v laser, you could use 2x CR2032 batteries to power it...  |
if you don't mind dealing with lithium cells you can just use some 14500s in there. basically a lithium cell.. AA sized. Dropin solution but you
must make sure that your circuit can handle the 4.2V/cell, cause that is what a lithium cell is hot off the charger.
If that doesn't float your boat, you may try a LiFePO4 14500. less capacity but is 3V, or closer to 2 alkalines in parallel. can handle up to a 10C discharge.
Another idea is to try NiMH cells. Alkalines are horrible when alot of current is required.
I would forget about CR2032s. like alkalines they cannot provide alot of current. That is why two coin cells don't burn out the LED in photon lights.
