Battery
To charge the battery with a bench power supply, see this tutorial: Cómo Cargar una Batería de Litio con una Fuente
The main pack uses Molicel P42A cells in a 13S4P configuration, providing a nominal voltage of about 48 V. A separate 12 V car battery supplies the sensors to remain compatible with the Formula Student car.
For battery placement rationale see the FAQ.
