Not 25C
I previously stated that these batteries are unable to deliver 3 amps without dropping below 3 volts. I was wrong. The mating cables I was using in the test had excessive resistance. I don't know if they are really 25C, but URGENEX deserves 5 stars for their customer service. They refunded my money when I didn't even request a refund.

Not great.
2 out of the 5 don’t charge. When they are charged, I get about 3-5 minutes with my stock alias quadcopter which they do NOT fit in. They are too wide. Super cheap though. Edit: I received a full refund and got to keep the working batteries after writing this review. Very good service!

Works with Traxxas Alias
This works with a Traxxas Alias Quadcopter. It’s thicker than the Traxxas battery, and is a tight fit. Plug is the mating end for the Alias interface plug, an adapter isn’t necessary. Once it slides into the bracket, it does have a tendency to want to stay at a slight angle. If you gently push from the front and guide it with a slight lift at the back, it falls into place. Removing is the process in reverse. I use a small popsicle stick to help push it out. First flight after charge was 20 minutes. I think this is worth the money.

BATTERIES DISHCARGE ALMOST IMEDIATELY
TLDR: original battery that came with drone provided more flight time than all 5 batteries combined. Followed instructions for charging. Once fully charged I installed one of the batteries into my Sky Viper GPS drone. Controller app showed battery at 100%. Immediately upon takeoff (before even 2 feet off the ground) the charge dropped to 77%, then immediately to 55%, then 32%, and 12%. The drone didn't even make it to elevation before it gave me the "Battery critically low: activating return" type message. Similar results with all 5 batteries. Attempted multiple recharges to full with the same result each time.
