Note: These batteries only fit pre-2025 versions of the Playable Battle Robot Kits. In January 2025 we upgraded the kits to use 9V rechargeable or disposable batteries.
The NiCad batteries that come with the Playable Battle Robot Kits last up to 15 minutes - but sometimes that isn't enough!
Grab a spare or two for your robot and don't be stuck waiting for a recharge.
Ensure you use the proper charger that came with your robot. Do not charge a 7.2V battery with a 4.8V charger, or vice versa.
These Ni-Cad batteries are 700mAh and will take around 2hrs to fully charge using the included 250mA USB battery charger. Plugs are "SM-2P".
Choose the configuration that matches your robot (otherwise it won't fit!):
4.8V battery in a 1x4 configuration: Dragon, Drill Head, Hammerhead Shark, Jackrabbit, Jigsaw, Nile Crocodile, Sawfish, Snapping Turtle, Stag Beetle, Trident
4.8V battery in a 2x2 configuration: Colossus, Rage Wheel, Rattlesnake
7.2V battery in a 1x6 configuration: Mustang
7.2V battery in a 2x3 configuration: Tornado, White Rhino
