Perfect battery!
Battery last a long time and I could fly rc planes for a long time. The price is unbeatable and and the quality is great.

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.

Size of batteries
Size of batteries are misleading

More playtime.
I use these to run the remote control plane. One battery just was not enough. I could spend a lot more time out in the field with many more batteries as this.

Beware, not capable of 25C discharge
These are labeled 25C but in actual use, they are nowhere near that. The four year old batteries I have been flying in my Eflite UMX Ultrix give me 4-5 minutes of aggressive flying. Telemetry reports that the voltage is above 3.5V even at full throttle until at least half way through that flight (used to be 6 minutes when new). A six minute flight to 3.5V is a 10C discharge AT BEST.By contrast, these brand new Urgenex “25C” batteries in the same plane at the same average 10C discharge drop below 3.5V and activate my low battery alert IMMEDIATELY on full throttle application for the first take off.A small part of the issue might be the JST connector but since I plan on returning the batteries, I am reluctant to cut a connector off and replace it with a better connector to see if that is a contributing factor.
