When it comes to batteries, the JJRC C8816’s original 7.4V 1200mAh lithium battery actually performs fairly well in terms of battery life. Typically, you can use it for around 30 minutes.

Nevertheless, if you often drive the vehicle vigorously like I do and want to prolong the battery life, choosing a battery with a larger capacity is a wise choice.
Moreover, when replacing the battery, it’s essential to check whether the size of the battery is suitable.
Make sure that it can fit into the body space which measures 29 x 24 x 17 cm. Also, take precautions to prevent water from getting into the battery compartment.
