Графический индикатор уровня заряда батареи электровелосипеда.

Подключите индикатор к батарее, красный провод плюс, черный провод минус.

Как видно из оригинальной инструкции приведенной ниже, при включении с нажатыми кнопками можно войти в режим настройки и задать параметры батареи.

Дальше первая кнопка переключает тип химии, а вторая количество ячеек.

Дополнительные функции включаются с помощью паяльника. ;=)

Этот индикатор не работает с элементами Lifepo4 т.к их напряжение постоянно на всем ходе процесса разряда.
