Finally one of the secret circuit boards of the pi-top! Sadly the most exciting thing to find is the easy to release pin connector. Nothing to find here for the adhesive and soldering police!

Responsible for the battery management is the Texas Instruments BQ40Z60 chip.

Texas Instruments MOSFETs

12 A Fuse

Each of the four batteries claims an 10.73 Wh capacity. All together they shall guarantee you 12hrs of work without charging the pi-top, which is enough to fly from Hollywood to Barcelona.
