Battery Charger


Charger for use with our 12V Slim Battery. The charger is wired with an XT30 fmale connector and a standard, grounded US power plug. 

*Do not plug the Battery Charger directly into a Control Hub or an Expansion Hub, this will damage the Hub and void the warranty.

Best Practices

All rechargeable batteries have a finite lifespan. Factors that affect lifespan include the number of discharge/charge cycles and the average loading of the battery. The following best practices can help maximize the lifespan of your battery:

  • Charge rate
    • Minimum: 1.5A
    • Maximum: 3.0A
    • Recommended: 1.8A or 2.0A
  • Do not overcharge
    • Disconnect the battery from the charger once it indicates a full charge.
    • Typical charge time does not exceed 2 hours.
    • Do not charge a battery that hasn't been discharged significantly.
      • For example, running the robot under minimal load for a few minutes will not significantly discharge the battery.
  • Minimum no-load voltage: 9.0V
    • Discharging the battery past 9.0V can reduce the lifespan of the battery and can permanently damage the cells.
    • Periodic dips below 9.0V when under load is expected and OK.
      • For example, don't forget to unplug your battery after you are finished running the robot and don't run your robot until it completely stops responding!
  • Temperature
    • Let the battery cool before and after charging.
    • The battery may feel warm after heavy loading or after charging. This is normal.
