I am soooooo confused about batteries! What do I need for my flashlights!

@kjk200:

You order only bodies - which drop-in will be built in?

For example: The XM-L is a good flooder (big spot, but not extrem distance). Other drop-Ins are better for distance but have smaller spots (for example the R2 Drop-Ins).

What do you prefer?

Do you want to use only 18650 (=3,7 Volt) or 2 CR123 (=6 Volt), too? Only 18650 would be better, because many drop-ins work fine with max. 4,2 Volt.

For 6 Volt you have to search.

What's mAh:

Short words: More mAh, longer runtime of the flashlight.

But don't buy cheap crap like 3600mAh or 4000mAh - that's fake mAh - they are much less.

Take a look at the battery data base of the forum:

The flame trustfire are good or the Hi-Max of ebay - both have a good Price/Quality.

You are a beginner - please take protected batteries. They are saver.

Your DX charger:

I do not have any information about it (have never seen a test of it).

You wrote: Deal Extreme. It's a good shop, but often shipping takes a long time (for about 4 weeks), Manafont is faster (I think most users of the forum get the items after 2-3 weeks).

I post the products of DX and if Manafont (they have a better charger, which DX not offer):

18650:
