Ensure the GS44B is actually receiving power from the most positive cell in the series.
A "cracked" schematic in this context usually refers to a created by the repair community. These diagrams reveal how the GS44B and GS54B interact with the MOSFETs that gate the power flow. Common Failure Points in GS44B/GS54B Circuits gs44b gs54b nmc561 schematic cracked
The thin traces leading from the cells to the GS44B are prone to corrosion. If the chip loses the signal from even one cell, it will shut down the entire output for safety. Ensure the GS44B is actually receiving power from
Often serves as the primary Battery Protection IC. It monitors individual cell voltages and prevents overcharge, over-discharge, and short circuits. and short circuits.
