table).

Battery (12 V, 17 Ah, VDS)
Battery (12 V, 26 Ah, VDS)
Table 2: Permitted batteries
NOTICE
Hardware damage
Due to CE conformity only UL94-V2 batteries may be used.
Notes
To achieve the system voltage of 24 V, two batteries must always be
connected in series.
Batteries are not included in the scope of supply of the stations and must be
ordered separately.
The battery capacity determines the charging current. The charging current
must be taken into account when calculating the power supply.
The dimensions of the batteries are needed to determine the housing type.
Restriction of the battery dimensions
With greater battery capacities, the additional empty housing (Standard) should
be used with a 150 W power supply.
