- Integrated BMS: Advanced Battery Management System protects your workstation from over-current and thermal spikes, crucial for the GT80’s heavy-duty internal architecture.
- Calibration: For the most accurate runtime reporting on these 7500mAh cells, we recommend performing 3 full charge/discharge cycles (100% to 10%) upon installation to sync the Windows power meter.
