Battery Beak – The Smarter Way to Trust Your Batteries

Don’t let a weak battery cut your performance short. The Battery Beak is a compact, powerful battery load tester designed to give you instant, reliable answers about your battery’s readiness. With the ability to apply up to an 18 amp load, it measures state of charge (SOC), internal resistance, and overall battery health.

Why Teams Rely on Battery Beak

✔ State of Charge (SOC)

• Quickly confirms if your battery is fully charged.
• Uses no-load voltage measurement, just like a multimete

✔ Health (Internal Resistance)

• Tested by applying up to an 18A load.
• Voltage drop reveals the battery’s internal resistance—the best way to assess long-term health.
• Since batteries are relatively linear, this 18A test accurately reflects performance even under hundreds of amps.
• Track resistance over time to know exactly when to retire a battery before it fails in competition.

Features That Set Battery Beak Apart

• Supports Multiple Chemistries
  • Works with all battery chemistries.
  • Extra diagnostic features for Lead Acid and NiMH.
  • Handles a wide range of Amp-Hour/Voltage combinations.
    
• Instant OLED Display Results
  • High-resolution screen delivers data in less than a second.
  • Shows:
  • Internal resistance
  • SOC
  • Open-load voltage
  • Voltage at 1A and 18A loads
  • Battery status: Good, Fair, or Bad
    
• Smart Power Management
  • Runs without external power.
  • Auto power-down means it can stay connected indefinitely without draining your battery.
    
• Built for the Field
  • Rugged ABS/Polycarb blend housing stands up to tough use.
  • Plugs directly into Anderson SB50 connectors.
  • Optional adaptor available for Tamiya-type connectors.
    
    

Why You’ll Love Battery Beak

With the Battery Beak, you’ll know within seconds whether your battery is competition-ready or heading for the scrap pile. No guesswork, no surprises—just confidence that your robot has the power it needs when it matters most.

The Battery Beak is a battery load tester capable of delivering an 18 amp load and measuring a battery's internal resistance, state of charge (SOC), and determines the overall health of a battery.
