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.

This specific blend is known for high energy density and stability.

Often serves as the primary Battery Protection IC. It monitors individual cell voltages and prevents overcharge, over-discharge, and short circuits.

Check the balancing resistors (usually marked "101" or "470"). If one is charred, that specific cell bank was overcharging, indicating a bad cell or a failing GS44B.

Are you attempting to or are you looking to repurpose the cells for a different project?
