I'm running mine with these:

This is the charger I'm using:

DX also offers them together:

Runtime is about 15min on high and 1:30h on medium. Never checked at the lowest output. These batteries are so small and cheap that you can always have several spare-batteries with you.

what about protection? How do i know when my batteries need to be recharged?

They don't have any protection. After all, this is a pretty small cell so there is not much space for a PCB. The highest mode is quite sensitive to a decreasing battery voltage, so you should notice in time, when it's time to charge your cells. I usually charge my batteries whenever I used the light for more than a few minutes or at least when there is no more difference between the highest and the medium mode. This has worked out for the last two years.

I have been doing exactly the same thing on my QMini's for a long time. I purchased a batch of these cells and keep them topped up by charging them regularly. The capacity is nowhere near the one written on them but the general performance is very good.
