TENERGY 7.4v LIPO 1200mAh STICK
This is your standard Lipo battery. Lipo batteries are advantageous as they last longer, and are not affected by cold weather like Ni/MH batteries. However, care must be taken when using a Lipo battery to ensure lifespan and that damage is not caused to the battery. This battery will perform roughly the same as a 9.6v Ni/MH small type battery.
****WARNING**** Only use a Lipo specific smart charger to charge your Lipo battery. NEVER use anything else, as this could result in an explosion. Adhere to all precautions in the manual included with each Lipo battery****
