RC monster truck, needs battery (Letchworth SG6)

GPTOYS S911 1/12 Scale Electric RC Car 2.4Ghz 2WD.
This car is in good condition, a couple of plastic parts are broken but spares are included so easy to fix.
It was fast and good fun for my son, but the cars battery is dead and it needs a new one. I think they are available from China via Amazon, GearBest etc.
Comes with car, body shell, controller, spare body securing clips, spare motor and receiver board, and charger.
Box is in a tatty state, instruction manual included.
Just needs new 9.6V battery for the car and AA batteries for the controller.
Two old batteries parts are included, I tried to make 1 good one from two but no luck.

Fair chance on this so will wait a day before replying, genuine freecyclers only please.
