EcoPower "Electron" 6S Li-Poly 30C Battery Pack (22.2V/3400mAh)
Ok, after fifty cycles on my Align 500 DFC PRO I have to say these batteries are a great Investment. I fly mild 3d at 2800 head flat curve all stock and can get 8:30 flight time with 75% battery use. No problem at 7:30 (where I have my timer set). Voltage difference between cells 7mV and charge 2 @ 1.5 C in 33 minutes. I bought balance lead extensions (a must have item) so short balance lead is a non issue. No signs of puffing and I always leave my batteries at storage charge unless I know I will fly the next day. Charge time from storage is 10 minutes. They come down warm not hot. If your not a pro or super experienced 3d pilot I think you would never know the difference. I have a set of 2900 70 and I can't tell any difference other than longer flight times on the ECO's. These batteries work great.

I got this for my T-Rex 500, and it fits perfectly. Stock. With-out any modifications. It is the same size as the 2500 mah packs I got elsewhere. It is heavier than my 2500's, but the extra weight provides better balance than before. I have not broken it in yet, so I don't know about flight times yet. I will be getting several more.
