Hart 20V Battery Pinout Diagram: A Comprehensive Guide

1. Find B+ and B- – Measure DC voltage across the two largest outer terminals. That’s your main power.
2. Identify thermistor pin – Set multimeter to resistance (kΩ). Measure between each small pin and B-. A normal room-temperature reading of ~10kΩ indicates the NTC thermistor.
3. Identify communication pin – The remaining small pin will show no direct continuity to B+ or B- and no resistive load. That’s your data line.

Below is the standard pinout configuration for Hart 20V Lithium-Ion batteries. Note that orientation is critical; we will use the standard orientation of the battery label facing you. Hart 20v Battery Pinout Diagram

Cut-off Voltage: ~15 Volts (The BMS will shut down to prevent cell damage). Hart 20V Battery Pinout Diagram: A Comprehensive Guide

Positive (+) to TH / ID: ~20V (Commonly measured across these internal circuits). Negative (–) to C: ~20V. Find B+ and B- – Measure DC voltage

The pinout configuration typically follows this layout when looking at the battery connector with the pins facing you:

4. B- Sense (Optional)

• Used only in higher-capacity packs for cell balancing during charging.
• Not present on 1.5Ah or 2Ah packs. If present, it connects between cell 3 and 4 in the series.
