I just ordered 2 ***** LiPo 2200mah 2s 20c batteries Not only did they take 3 MONTHS to get here, but when they did, both batteries IMMEDIATELY didn't work out of the box. After some digging, I found they both had THE SAME poor connection on the positive terminal. I didn't want to waste my money sending them back and waiting another 6 months and paying shipping to send them to/from ching chong land, wherever they came from, for half the price of the batteries, so I opened them up and tried to solder the connections for nearly 3 hours. I was unsuccessful.

I bought these because they seemed to have a good reputation from a few people and some good reviews on their website. Apparently the reviews are fabricated. Buyer beware.
