This is a library for the Arduino to drive and LTC6803-based circuit.
The circuit consists of three HF-isolated 12-cell monitors originially designed for solar applications. A friend got a number of these second-hand parts so I gave him a hand to communicate witht the chips on board.
Since the circuit was covered in protective resin, it took us some time to figure out what the onboard CPU was ; so in the mean time I removed one and made a connector for an Arduino or similar micro-controller.
The file 36-cell_battery_monitor.pdf is a cut-down (or rather built-up) version of the board schematic. Much is missing and some things have been simplified for the sake of time and usability.
