We build a 18650 battery capacity tester for a Li-Ion 18650 Cell which will discharge a fully charged 18650 cell through a resistor while measuring the current flowing through the resistor to ...

The true measurement of a battery’s capacity is essential for many scenarios. A capacity measurement device can solve the problem of spotting fake batteries as well. Nowadays fake Lithium and NiMH ...

The Arduino based capacity tester of true battery power is capable of measuring almost any type of rechargeable or non-rechargeable batteries by fully discharging the battery with known current and ...

Programming Arduino for Battery Tester After soldering the components on perf-board, let’s program the Arduino Nano to test the battery capacity using the time and current readings.

This is a full-stack application made with React.JS, Node.JS and PostgreSQL to generate and save lithium-ion battery performance reports. The application gets the data directly from the RS232 port of ...

You can also go the 9v battery route plugged into the on-board regulator of the Arduino but the low mAh rating of a 9v won’t allow your project to stay running for very long.
