Hi there we have had a few calls today about how to and why to connect batteries in series or parallel or a combination of the two. So I thought I would try to shed some light on these series and parallel battery connections.
lets start with the basics
This is illustrated below
in the first image is a series connection of two batteries
The parallel connection of two batteries is when you connect the positive to the positive and the negative to the negative with this type of connection you get the same voltage and a doubling of the capacitance or Amp Hours of the batteries.
Now if you use the series and parallel connections in a combination of the two of them then you can create a battery bank that has your desired voltage typically 12, 24 or 48 volts then wire the strings of batteries in parallel to develop the desired Amp Hours for your battery bank.
