Thunder Power 7.4 Volt
2100 mAh 2 Cell Lithium Polymer Battery
Fly lighter and longer with Thunder Power lithium polymer batteries. They weigh less than other NiCd or NiMH packs of the same capacity. Lithium polymer batteries hold a higher percentage of their capacity at the rated discharge rate, which means longer run times. You can expect flight times of 30 to 60 minutes in some slow and park flyer applications.
