Amp hours essentially doubled you are getting twice the charge capacity when you connect batteries in series. Once this voltage is achieved we can calculate our recharge rate by looking at the amps of our recharging current.
Parallel Serial Battery Wiring Basics
12 volt batteries in series vs parallel. These are measured by volts and amps. How to wire your 12 volt batteries in series or parallel to get one large battery or increase the voltage. If your battery bank consists of 12 volt batteries wired in parallel your recharging current will have a voltage at or a little above 12 volts. A parallel configuration is not meant to. Voltage stays at 12v there is no voltage drop even when the charge dips below 50 of the batteries capacity. Following this example we will have two 24v 200ah blocks wired in parallel thus forming overall a 24v 400ah battery bank.
Combining the parallel connection with series connection we will double the nominal voltage and the capacity. 2 12 volt batteries in series will give you 24 volts. Advantages of using 12 volt batteries in parallel. Charging 12 volt batteries wired in parallel requires a 12 volt battery charger. I recommend connecting 4 12v batteries in parallel so that you have a normal amount of power for an extended period of time. You can use this for your boat cabin rv or your solar setup at home.
How to wire batteries in series. Lets start with the series method as we compare series vs parallel. In contrast batteries connected in a parallel configuration are able to increase the amp hour capacity of your batteries at the same voltage. For example two 6 volt batteries connected in series will deliver 12 volts of output but will carry the same amp hour capacity. Two 12 volt batteries wired in series produce 24 volts but the capacity remains the same as one for a 12 volt battery. Batteries may be wired in parallel or in series.
During the connection it is important to pay attention to the polarity use cables as short as possible and with an appropriate section. Two 12 volt batteries wired in parallel continue to produce 12 volts but the capacity doubles. If you were to connect 4 12v batteries in series you would end up having a 48v setup that could really cause some major damage if not handled properly. 2 12 volt batteries in parallel will still give you 12 volts but the amps will be doubled. Hence when charging these batteries it is important to utilize a charger that satisfies the 12 volt capacity that is necessary for both the 6 volt batteries connected in series. For example these two 6 volt batteries joined in series now produce 12 volts but they still have a total.
Connecting batteries in series adds the voltage of the two batteries but it keeps the same amperage rating also known as amp hours.
