I really wouldn't recommend this battery and here is why...

Manufacturer: Apogee

Number of Cells: 3

Max Constant Discharge Rate: 20C (30amps)

Capacity in mah: 1500mah

Connector used - deans etc: Deans Ultra

Type - (lipo nimh nicd etc): Lithium Polymer

My two electrifly batteries were getting worn out, so I bought three of these Apogees. The weight and sheer power of these batteries was spectacular for the price, or so I thought.

These retail for about 50 bucks, but buyer beware, you get what you paid for. Here is my story:

I bought two of these packs. The first one had the negative and positive wires BACKWARDS. It was manufacturered wrong!
The second battery slowly developed a problem where it would lose capacity with every use. It now sits at a solid 1200mah when it should have been holding 1500mah.

My third battery is fine and takes about 1510mah. But two bad ones out of three?

I sent the one that was wired backwards back to the manufacturer and it took them a full month and a half to get me a new one. I contacted them about the second battery, but they never emailed me back.

Other than that, the batteries do perform well. In my planes, at most, they pull 20 amps, and they can do that solidily without any problems. However, they do lose their power much faster than my Thunder Power packs.

Overall, I think I'll stick with Thunder Power in the future.
