Tenergy 7.4V 900mAh 25C LIPO Battery Pack for Blade CX & CX2 Helicopter

I am using this battery as a replacement to the Shimano Di2 system battery on my Trek SC TT bike. The battery fits perfectly in the seat tube for an integrated more aero setup. It is smaller, lighter, and lasts a lot longer than the stock Shimano battery.

This is my back up battery for my ICS CXP 15 fits in hand guard with ease. Just wish i could get these dimensions in 11.1 and higher mah lol. everyone i play with like how small it is and the fact it fits in their AEGs.

It is not holding much charge when compared to 800mah battery of eflite. Flight times are atleast 2 minutes lesser. But this is cheaper compared to eflite batteries.

Because of these batteries, I only buy Tenergy batteries for all my RC stuff. They last a long time, even if they are somewhat neglected. No puffiness like other brands I've tried.

Item is working great.... thanks!

Makes my Helicopter run for a long time. Good price too. Charges fast too. Thanks for reading my review. Have a nice day.

Charged it once, never worked again.

it is very small can fit almost any boat and has a really high discharge making boats or rc vehicles fast but not very long i suggest for racing only
