Use this as a reference — match shapes and labels on your specific pack before wiring.

When looking directly at the interface of a HART 20V battery with the plastic locking latch pointing upward, you will find five primary terminal blade receptors. Pin Position Typical Label Voltage / Signal B+ Main Positive Terminal Nominal 18V / Max 20V DC Middle-Left C1 / ID Balance/Identification Internal Cell-Bank Voltage Telemetry Center TH / T Thermistor Signal Temperature-Dependent Resistance (NTC) Middle-Right C2 / Data Battery Communication Serial Data / Logic Monitoring Far Right B- Main Negative Terminal System Ground (0V Reference) 2.

Many Hart batteries rely on the tool itself to provide low-voltage cutoff. Using just the (+) and (-) pins without an external protection circuit could lead to over-discharging and permanent battery failure. hart 20v battery pinout diagram better

If the battery feels extremely hot during use, allow it to cool before placing it on the charger, as the charger will report a "Temperature Out of Range" error. HART 20V Battery Charging Behavior

If a battery will not be used for several months, it is generally recommended to store it at approximately 40% to 50% charge rather than fully depleted or fully charged. Use this as a reference — match shapes

The HART 20V battery system, sold primarily through Walmart, has gained a massive following for its affordability and performance. However, for DIYers looking to repair a pack, build a custom power tool adapter, or use the batteries for robotics, understanding the is essential.

A standard Hart 20V lithium-ion battery typically features a 4-terminal or 5-terminal interface on its connector slot. When looking directly at the battery terminal slot with the latches facing up, the pins generally follow this layout from left to right: Deep Dive Into Pin Mechanics Power Rails: B+

A standard Hart 20V lithium-ion battery pack communicates through an external aligned horizontally. Looking directly at the battery terminal slots with the latch facing up, the pin layout functions as follows from one side to the other:
