6. BUILDING A BATTERY BANK
The MLI Ultra supports 12V, 24V, 36V and 48V systems.
Requirements:
• Only create battery banks with batteries of the same type and capacity.
• The batteries have the same product code and software version. Do not mix with other models.
• Make sure that all batteries are fully charged before creating a battery bank to ensure balancing is
optimized.
• Use properly sized fuses and wiring.
• Keep the cables between the batteries as short as possible.
• All battery-to-busbar cables should be of the same length.
• Install the batteries as close as possible to the charger.
• Mastervolt recommends one charger for batteries that are connected in series.
• It is best practice to label the batteries (e.g. Primary, Replica1, Replica2).
Series and parallel connections
Note: in the following drawing, the fuses are not depicted. For safety reasons, always use properly
sized fuses in the positive cables of batteries in parallel connections.
