I bought some Ultrafire 4200mAh batteries via eBay. They turnout to be fake with no short circuit or over charge protection as it says on the lable. According to the iMax B6AC they are around 2200mAh (which is about all we expect). Moral of the story; Unless you want these for free don't buy them. The supplier has offered a full refund. My dillema is do I shut off supply by dobbing them in to eBay or do I buy more and lodge a complaint knowing I'll get my money back?
