Great Batteries
These batteries are great! I purchased two additional ones for my Twister Helicopter, but also use them in my slow fliers. The Li-Pos can hold so much more power than a Ni-Mh. These 800mAh batteries are about 1/4 of the size of my 300mAh Ni-Mh batteries.
I give this product 5 stars. Review by Hoppes, Matt
