3. Battery bank wiring

3.1 Battery bank At the heart of any Victron system is the battery. A battery bank can consist out of a single battery but can also consist out of multiple batteries that are connected to form a battery bank. Commonly referred to as the house battery. The reason for doing this is to either increase the battery voltage, increases the battery capacity or both.

A battery bank is when: • When two batteries are connected in series their voltage increases. • When 2 batteries are connected in parallel their capacity increases. • Series/parallel combinations are also possible. Some examples:

Two batteries in series

Single battery

Four batteries in series/parallel

Two batteries in parallel

Four batteries in series
