Hey everyone.
Essentially, I am working on, quite possibly, one of the smallest, CC but high-powered red lasers. However, I am in need of a small battery... one capable of providing roughly 275mA at most (without essentially shorting it.
However, my limits are roughly 10-12mm in diameter. Length isn't a big deal, but the smaller the better.
It also needs to be li-ion (not lifepo4, won't provide the voltage necessary)... any suggestions for quality, low internal-resistance li-ion batteries? I am doing searches while writing this, but may as well ask for assistance as well.
EDIT: Actually, the smaller the diameter the better (going to make the host one solid object for heatsinking purposes).
EDIT 2: Found out about 10180 li-ions and 10280 li-ions. These look ideal for me (good difference in diameter from the usual 12mm maximum. However, I can't find any protected versions of these cells (I would deal with extra length for protection), but I need them to be protected because there will be no protection mechanism from over-discharge while the laser is running and I don't want to go about killing batteries every other day or so.
