According to user-reported diagnostics, here are the expected voltage readings (when fully charged) between the pins: ~20-21V (Nominal 18V) Negative to TH: ~0V (Typically resistance-based) Positive to TH: ~20V Negative to ID: ~0V Positive to ID: ~20V Negative to C: ~20V Positive to C: ~0V Safety and Internal Structure
: The internal pinout logic (Positive, Negative, Thermistor, ID) functions identically. This makes Ryobi-to-Hart 3D-printed adapters highly effective for cross-platform tool use. Safety Systems and Battery Management (BMS)

Respect these connections, never bypass safety features, and you’ll get years of reliable service from your Hart 20V ecosystem. Hart 20v Battery Pinout Diagram
These are direct connections to the 5S battery pack, allowing full power transfer.
This is the ground or negative terminal.
While marketed as a "20V Max" system, this nomenclature represents the maximum initial battery voltage measured without a workload. Key Voltage Thresholds These are direct connections to the 5S battery
The Hart 20v battery is a popular lithium-ion battery used in various power tools and devices. Understanding the pinout diagram of this battery is essential for ensuring safe and proper usage, as well as for DIY enthusiasts and developers who want to create custom battery packs or adapters. In this article, we will provide a detailed overview of the Hart 20v battery pinout diagram, its features, and applications.
The Control (C) pin is primarily used by the charger to manage the charging process. This pin acts as a "gatekeeper" for the battery. The charger likely uses the Control pin to "enable" the battery's internal Battery Management System (BMS). Once the charger determines it is safe to proceed (based on data from the ID and TH pins), it sends a signal through the C pin to the BMS, which then allows the charging current to flow into the cells. This prevents the battery from being charged by an unauthorized or potentially dangerous source.
: This pin monitors the battery's temperature. It is a critical safety feature that prevents the battery from charging or operating if it is too hot or too cold. Key Voltage Thresholds The Hart 20v battery is

Working with Lithium-ion batteries is dangerous. Incorrectly wiring batteries can lead to fire, explosion, or severe injury. Always use appropriate protective equipment and check connections with a multimeter before connecting to a load or charger.
