I have mixed experience with those cheap batteries.
1. i bought from dutch webshop two batteries for my 50d and 400d. the accus ware rated with higher capacity than OEM but actually they ware worse than OEMs. After 1 resp. 2 yaer usage on 50d /400d they both died/ I opened them and i sow that tha problem is not in batteries, but in protection electronics. To safe money they use only one mosfet and combined R network to control the overvoltage protection. after modification i use this battery up until now in RC cars of my son and they are still ok
2. I bought second one from well known http://www.dx.com The batteries are OK they serve me until now and i don't see any difference from oems.
