Sphero RVR Battery

Removable and rechargeable battery for the Sphero RVR.


Pick up a back-up battery so you can power your RVR with one battery while the other one charges because who needs sleep when there’s driving, coding, and hacking to do?

How do I charge the RVR's battery?

You'll need to remove the RVR's battery in order to charge it. Charge times will vary based on the output. We recommend charging the battery via a wall outlet.

How long will I be able to play on a full battery?

The RVR itself will drive for about two hours on a full charge. With that in mind, remember that additional devices will drain the battery faster. Your mileage may vary if you start streaming 4K YouTube videos of cats on your Raspberry Pi 4 topper.

How long does it take to charge the battery?

Charge time will vary based on the type of USB charger the battery is plugged in to as well as the charge level already in the battery. The following are estimated charge times from empty based on types of devices it is plugged in to.

  • 1A charger (USB port on a computer, basic phone charger) - 10-12 hours
  • 2A charger (Tablet charger, 2.1A labeled phone chargers) - 4-6 hours
  • Quick Charge 3.0/USB-PD (Quick charge labeled charging brick, high-end phone chargers) - 2-4 hours
    • Note: Requires USB-C to USB-C cable (not included)

How can I prolong my RVR's battery life?

The RVR will provide power via the USB and universal expansion port even when it appears to be off, so it is best to disconnect your projects when not in use to avoid draining the battery with them. You can also remove the battery when not in use to avoid slowly draining it.
