7.2 Charging the battery
The battery is charged to a Voltage of 56.8 V. The battery starts
charging with a constant current stated as the max charging cur-
rent on the charger. When the battery reaches its max Voltage
the charger will continue charging at constant Voltage. When
the battery is fully charged the charger turns of. NOTE: there is no
float charging stage! This is to increase the battery lifetime.
Constant current
: charging at max current as stated on the char-
ger.
Constant voltage
