From the project

Avionics files related to new overhauled EPS schematics, pcb design, and documentation

Electrical Power System (EPS) for PVDX — battery charging, regulation, and power distribution.

Four 2S battery packs (8x Tenergy 30005-0 18650 cells) feed a charge/regulation chain built entirely from dedicated power-management ICs, with no onboard MCU — charging, cell balancing, and telemetry are handled in hardware and reported to the compute board over I2C.
