4S Lipo Battery EC5 5000mAh 14.8V 50C RC Lipo Battery Pack Compatible with RC Car Truck Quadcopter Airplane Helicopter Boat

Great alternative to the more expensive ones

Capacity has been great for runtimes in my tlr typhon. Connectors are high quality. These are some of the highest quality lipos available on Amazon.

Good battery.I used this to start my 2 stroke.R c airplanes and my gas engines works great charges pretty good

Great battery and price!

I use them in my Jets that take 8s I double them up, I also use the 6s in my jets that use 6s, they were fine but I wouldn't fly full throttle the whole flight you need to take a little easy on any battery in a jet, short burst of full throttle or fine 10 or 20 seconds at a time I'm just

I like the way this battery performs,I use it to power an RC plane.

Excellent burst output. Cells maintain balance within 0.01 Volts at all times. I am charging at 5 Amps and a 2700mAh balance charge takes only 35 minutes. I have only 10 cycles on these packs so far, so I cannot say anything about battery life.

I've now been using the HRB batteries for over a year,3S, 4S, 5S & 6S units with the larger ones being 5000 mah units. None of them have puffed up since I've had them unlike others. The internal resistance is good, in the 2-2.2 mohm/cell area. I use the larger ones in Motion RC's Avanti S, Hangar 9 Beast, Corsair and Katana 50 with good results unlike others. Based on my experience, these batteries are serving me well!
