LiPo Battery Health Monitor Kit with Arduino Nano + LED
LiPo Battery Health Monitor Kit — Track Charge Cycles Like a Pro with Arduino Nano
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Battery health determines how long your drone, RC car, or wearable project can run. This kit turns an Arduino Nano into a precise LiPo battery analyzer that shows real-time charge current, voltage, and counts every full charge cycle on a bright OLED display. Whether you're testing batteries for a school science exhibition or curious about what your power bank does, you’ll see exactly when a battery is full, how much current flows in, and how many times it’s been cycled — all without a multimeter.
What You'll Build
You’ll assemble a compact monitor that plugs between your USB charger and a 3.7V LiPo battery. The OLED screen displays live voltage (to 0.01V resolution), charging current in mA, and a persistent cycle counter that increments each time the battery reaches full charge. It’s a practical tool that helps you spot underperforming cells, estimate remaining runtime, and understand charging profiles — perfect for any electronics workbench at home or in a school lab.
What You'll Learn
- How to read voltage and current using an INA219 sensor with I²C communication
- Calculating charge termination point and detecting full charge automatically
- Storing battery cycle count in Arduino EEPROM so data survives power-offs
- Wiring an OLED display and building a real-time monitoring dashboard

Who This Kit Is For
ATL Tinkering Lab students investigating renewable energy concepts, CBSE Class 11-12 physics enthusiasts building a practical data-logging project, and B.Tech ECE/EEE first-years who want a hands-on sensor interfacing experience. Also ideal for drone hobbyists in India who need a dedicated LiPo cycle tracker without buying an expensive commercial charger. If you can follow a simple breadboard diagram, you’ll have a working device in an afternoon.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code inside the box to open the AI companion that walks you through each connection step by step. If you still need help, message us on WhatsApp — a real build specialist from our Bengaluru lab will guide you within a few hours.
Can I track how many times a battery has been charged over weeks?
Yes, the Arduino code stores the cycle count in EEPROM, so it remains even when you unplug the battery. Every time the charge controller signals a full termination, the count increases and appears on the OLED. Reset it anytime with a button press or serial command.
Is the LiPo battery safe for students to use in this project?
Absolutely. The included 1,000mAh LiPo comes with a built-in protection circuit, and the TP4056 module adds overcharge, over-discharge, and short-circuit protection. The current never exceeds 1A, and the PCB stays cool during normal operation. Adult supervision recommended only for soldering optional headers.
Can I monitor batteries other than a 3.7V LiPo?
This kit is calibrated for single-cell LiPo or Li-ion batteries with a nominal voltage of 3.7V. Using it with higher-voltage packs or different chemistries would require circuit changes. We’ve designed it specifically for the included 1,000mAh cell, but the code can be adapted by advanced users with knowledge of voltage dividers.
TP4056 + INA219 monitor LiPo charge current and voltage. OLED shows charge state and cycle count.
