Replacement battery?

Robotic kit for Raspberry Pi
1

Hi Sunfounder, I’ve been putting my pidog through some quite intensive workouts over the last year that I’ve owned it.

I have noticed that the battery runtime is starting to decrease and often shuts down completely if I try servo type functions e.g. walk.

Is it possible to purchase a replacement battery?

Thanks

I used 2 5000mah 21700 instead of 2 18650. It has a much longer life now.

To assist with your battery inquiry, please:

  1. Voltage Measurement:
  • When fully charged: Measure and record the voltage of each battery separately using a multimeter.
  • When completely drained: Repeat the measurement for both batteries.
  1. Regarding 5-pin Battery Replacement:
    While we can provide the battery, please note that shipping standalone batteries carries significant logistical challenges:
  • Most carriers reject battery-only shipments due to strict safety regulations
  • High probability of package return during security checks

Thanks hozdemir. That’s probably the route I’ll take. My pidog used to run for about 20 minutes, depending on what I was asking of it. But now it’s probably less than 10 minutes. I don’t think anything is amiss, just normal battery wear and tear.

Was it straightforward to make up the new battery pack? Connectors etc?

Thanks Sunfounder. Understood. I’ll source a replacement battery locally.

I cannot anyway do the measurements that you suggest, as I do not own a multimeter.
