Concerned about what I've bought...

So I asked for this light, cell, charger pack as a Christmas gift from a relative… http://dx.com/p/trustfire-x8-xm-lt60-5-mode-1000-lumen-memory-white-led-flashlight-with-batteries-set-2x18650-57749

But since then, I’ve read a lot more about the importance of good quality li-ion cells and chargers.

If I take sensible precautions, are the cells and charger in this kit ok? I should I just move them on unused and order up something like Panasonic or AW cells and an Xtar SP2 charger?

Thanks

I would order some better cells and a Intellicharge I2.

Something like this? Fenix, Nitecore, Zebralight, Eagletac, Olight and Maxpedition

Just brand name of any kind. I would probably go for Solarforce 2600 mah ones. AWs are way overpriced.
