I have recently came across some "UltraFire" 18650 Li-ion 3000 mAh batteries.
They are claimed to be 3000mAh and internally protected, on top of that they cost 1.9$ each on ebay.
It surely sounds too good to be true, has anyone tried them ? Or any other type of those cheap li-ions ?
I'm more worried about not having an "Ultra Fire" (pun intended) caused by them, than their 3Ah rating (which is surely fake isn't it ?).
