Gs44b Gs54b Nm-c561 Schematic -

The GS44B, GS54B, and NM-C561 are standard 5S Li-Ion battery assemblies. While official printed schematics are rare, their internal topology

The internet is littered with dead links, password-protected RAR files, and viruses labeled NM-C561.zip. Finding a legitimate schematic for the GS44B/GS54B is difficult because:

The most helpful aspect of the schematic for DIYers is the pinout. These packs usually feature a proprietary connector. However, the layout is almost always consistent with standard "slider" style packs. gs44b gs54b nm-c561 schematic

Standard Pin Configuration (Top View):

| Pin Position | Function | Wire Color (Typical) | Description | | :--- | :--- | :--- | :--- | | 1 (Outer Edge) | Positive (+) | Red | Main Power Output | | 2 | N/C or Thermal | White/Blue | Often unused or connected to an internal NTC thermistor. | | 3 | ID / Signal | Yellow/Green | Sometimes used for tool identification or fuel gauge. | | 4 (Outer Edge) | Negative (-) | Black | Main Ground | The GS44B, GS54B, and NM-C561 are standard 5S

Note: If your specific module is a "slide-on" style for Parkside tools, there is often a "T" (Thermistor) pin. This pin connects to a 10k NTC thermistor inside the pack. If you are bypassing the original charger, you generally do not need to use this pin for power.

You cannot rely on software to tell you which board you have. Flip the motherboard over. Near the RAM slots or under the M.2 SSD slot, you will see white silkscreen text. You cannot rely on software to tell you which board you have

Working with Lithium-Ion schematics carries risk. These batteries contain high energy density.
