Early report. I've run them through 24 hours of discharge/charge test cycles (BT-C3400 Universal Battery Charger Analyzer Tester) and as an electrical engineer, I like these batteries ... they are the real deal ... about 2150 mah capacity ... much better than ultrafire (1100 mah) and comparable to the (also good) DULEX brand.. Some have noted the batteries lack internal charge/discharge protection electronics. Cannot verify this as my system has built-in charge management.

If you have need for low cost, high performance li-ion cells, this seems to be a good deal.

Great batteries sofar, I have had them 2 weeks or so. I got 4 charged them all. Took them to work and I use them in a Ultrafire wf-501b flash light and a Ultrafire wf-502b flash light. Each light only takes 1 battery. I am an auto tech by trade and use my lights at times upnto an hour. They are used all day everyday for inspection and to provide light when I need to replace a part. The batteries are best I have ever used. I go through one battery in 7-10 days sofar. That is crazy great. I could not be happier with this product. I normally use the Ultrafire batteries... These blow those away by a large margin. I normally change them like every 3 days, and they normally do not last more then 15 - 18 months then they are done. So the test goes on. I will post again in a few months to say if they still are as good as they are now.
