Battery longevity depends heavily on the termination voltage of individual cells. Upgraded firmware tightens the balancing tolerance from the standard 0.02V down to a razor-sharp 0.005V. This ensures your packs achieve perfect balance without overcharging adjacent cells. Step-by-Step Guide to a Successful Update
Press and hold the designated bootloader trigger on the screen or internal board (refer to your specific batch documentation, as some revisions require holding a specific quadrant of the touchscreen while plugging in the USB).
