Designed for RC hobbyists, drone builders, and electronics enthusiasts, this handy tester supports 1S-8S Li-Po packs and features a bright LED/LCD display for instant per-cell and total pack voltage readings. Simply plug in your balance connector and get real-time data - no multimeter required. Fast shipping across India with 7-day warranty on manufacturing defects and dedicated technical support.

Specifications

Key Features

• Instant Per-Cell Readout: Displays the voltage of each individual cell as well as the total pack voltage, making it easy to identify imbalanced or weak cells.
• Wide Compatibility: Works with 1S through 8S Li-Po, Li-Ion, and Li-Fe battery packs using standard JST-XH balance connectors.
• Built-In Low-Voltage Alarm: An integrated buzzer sounds when any cell drops below a configurable threshold, helping prevent over-discharge and battery damage.
• High Accuracy: +/-0.01 V precision ensures reliable readings for safe charging, storage, and flight preparation.
• Ultra-Compact & Lightweight: Weighing only ~15 g, it easily fits in your field kit, toolbox, or RC gear bag.
• No External Power Needed: Draws minimal current directly from the battery under test - no separate power supply or batteries required.
• Plug-and-Play Operation: No setup or calibration needed; simply connect the balance lead and read the display.

Why Choose This?

• 100% authentic product sourced from trusted, authorized suppliers
• 1-5 day shipping, 7-8 day delivery from our Bengaluru warehouse to most locations across India
• Expert technical support included - get help with wiring, reading interpretation, and battery care
• Essential safety tool that extends battery lifespan and prevents costly failures
• Trusted by thousands of RC pilots, drone operators, and electronics hobbyists

How It Works

1. Connect: Plug your Li-Po battery's balance connector (JST-XH) into the corresponding port on the tester (match the cell count - 2S, 3S, 4S, etc.).
2. Read: The LCD screen immediately displays individual cell voltages and the total pack voltage.
3. Listen: If any cell is below the low-voltage threshold, the built-in buzzer will sound an alarm to alert you.
4. Decide: Use the readings to determine whether your pack is ready to fly, needs charging, or should be placed in storage mode.

Project Ideas & Applications

• RC & FPV Drones: Pre-flight voltage check to ensure safe and optimal flight performance; post-flight monitoring to avoid over-discharge.
• RC Cars, Boats & Planes: Quick field-side battery assessment between runs or races without carrying a bulky multimeter.
• Portable Power Stations: Monitor custom Li-Po/Li-Ion battery packs in DIY power banks, solar storage systems, or UPS builds.
• Robotics Projects: Integrate voltage monitoring into your robot's maintenance routine to prevent mid-operation shutdowns.
• Battery Maintenance & Storage: Identify cells that are drifting out of balance before they become a safety hazard; ensure packs are stored at the recommended 3.8 V per cell.
• Education & Lab Work: Teach students about battery chemistry, cell balancing, and safe Li-Po handling practices with a simple, visual tool.
• Professional Field Service: Technicians can rapidly verify battery health in commercial drones, inspection equipment, and
