Hart 20v Battery Pinout Diagram Better ((new))

The Hart 20V battery is a rechargeable lithium-ion battery designed for use in power tools, such as drill/drivers, saws, and sanders. It features a nominal voltage of 20 volts and a capacity of 4Ah or 5Ah, depending on the specific model. The battery is equipped with a built-in protection circuit that prevents overcharge, over-discharge, and overheating.

The HART charger communicates via SMBus (System Management Bus). If you try to use a generic Li-Ion charger (like an iMax B6) directly on B+ and B-, the battery will reject the charge. Connect your charger leads to B+ and B-, but also connect a 10k NTC thermistor between T and B- to simulate room temperature. Without this, the BMS assumes the battery is on fire (infinite resistance) and cuts the circuit. hart 20v battery pinout diagram better
