What is Series Connection and Parallel Connection for batteries?
Series Connection A series connection is used to increase voltage, while keeping capacity at the same level. Two serially connected 12V/120 Ah batteries make a combined battery set of 24V/120 Ah. In a series connection, the positive pole of one battery is connected to the negative pole of the other, with the poles that remain at the ends being connected to the system. Batteries with different capacities and chemistry should never be linked in series.
Series connection 24V/200 Ah.
Series connection 36V/200 Ah.
Parallel Connection Parallel connection is used when you need to increase your capacity, but keep the voltage the same. The positive leads are connected together, as are the negative leads. The cabling from the battery to the system should be: Positive from battery 1 and negative from battery 2 (or the last in the parallel connection).
Parallel connection 12V/400 Ah.
Series/parallel Connection If you need a 24V battery set with a higher capacity, you can combine series and parallel connections. The cables from the battery to the system must be crossed: Positive from battery 1 and negative from battery 2 (or the last in the parallel connection). Space when Installing Multiple Batteries Make sure there is sufficient space between the batteries when installing multiple batteries: There should be a ‘finger’ of space between them to allow the heat to be diverted.below.
