See full version: How To Connect Batteries In Series And Parallel
How do you connect batteries in a parallel configuration? Take a jumper wire and wrap it around the positive terminal of the first battery. Connect the other end to the positive terminal of the second battery. Take another wire and connect the negative post of the first battery to the negative post of the second battery. Connect your positive and negative wires to one battery and run your application. [links]
If you want to increase both voltage and amperage, you could connect multiple batteries in both series and parallel.
You will need at least four batteries to build this complex configuration. If you already have two sets of batteries connected in parallel, you can wire them together to form a series connection.
For example: let’s consider 2 sets of batteries 12-volt 150Ah wired in parallel and put them in series. This system will give you 24 volts and 300 amps.
When you connect two batteries in series, you are able to double the voltage while maintaining the same electric intensity.

Always use heavy-duty wires when connecting batteries in parallel. The increase in amperage can heat up the cables really quick and lead to damage.
A battery pack consists of two or more batteries that are connected with wires through their terminals. By connecting batteries to supply power for a single application, you can increase the voltage, amperage, or both.
Whenever you need more power or capacity, consider building a battery pack instead of installing multiple units. This would make your power supply more efficient and longer-lasting.
There are two ways to connect batteries to a power source: series and parallel. more
Knowing the difference between series and parallel circuits to charge batteries can help you improve the efficiency of your batteries through different methods as a result of the varying physics between series and parallel circuits. While charging batteries in series can restore charge to them by increasing the voltage across each of them, charging batteries in parallel functions differently. here
You can use a charger for the batteries themselves that uses the increased voltage output more effectively, but connecting batteries in series doesn't affect the AH capacity of the circuit, a measurement of how much energy the battery can store. This means you should focus on the increased voltage and ways to use that to charge multiple 12 V batteries by using, for example, a charger with the same voltage as each battery. more
One way to demonstrate a series-parallel circuit is to use four batteries with a single charger. Connect the positive output of the charger to the positive terminal of the first battery, and, then connect the battery's positive terminal to the positive terminal of the second battery. [links]
Be careful when working with circuits as you shouldn't touch the ends of wire unless they're insulated to protect themselves and avoid touching the circuit if the wires or batteries are wet. Don't mix sizes of batteries that have different voltages or amp-hour (AH) capacities, and use rubber gloves if needed to insulate your hands from electricity and protect yourself.
Series circuits send current in a single direction around a loop while parallel circuits send current in different paths across branches. Series and parallel methods means that charging 12 volt (12 V) batteries in line can use either a series or a parallel circuit. In series circuits, the current is constant throughout the circuit and the voltage changes across each element of the circuit.
Turn off and unplug your charger from the electricity supply. Disconnect the negative and positive wires from the battery terminals.
Batteries may be wired in parallel or in series. Two 12-volt batteries wired in parallel continue to produce 12 volts, but the capacity doubles. Two 12-volt batteries wired in series produce 24 volts, but the capacity remains the same as one for a 12-volt battery. Charging 12-volt batteries wired in parallel requires a 12-volt battery charger. The process is simple, but as the capacity of the batteries increases, depending on the number of batteries wired in parallel, it can take twice the time to charge two 12-volt batteries and three times as long for three batteries.
Check that your battery charger is set for charging at 12 volts. Twelve-volt batteries wired in parallel must be charged at 12 volts. If your battery charger produces a charge rate greater than 12 volts it may damage your batteries.
Connect the positive (red) wire from your battery charger to the positive terminal of one of the 12-volt batteries. The terminal is labeled “+.” The wire from the charger can be connected to any positive battery terminal. here
Connect the negative (black) wire from your battery charger to the negative terminal of one of the 12 volt batteries wired in parallel. The negative terminal is labeled “-.” You can connect the wire to any of the negative battery terminals. more
Plug in your charger to the electricity supply. Turn on your charger, ensuring it is set to charge at 12 volts. Let your batteries charge until the charger indicates they are fully charged. Some chargers have a light that illuminates once charged: others have a meter that shows the charge rate, and once it’s near zero your batteries are charged. here
Connect the negative wires together in the same fashion, and the wires off the last panel in the parallel circuit are connected to the battery.
Wiring solar panels to a battery is a convenient and cost-effective way to keep your power supply fully charged. This is especially useful for outdoor equipment such as golf carts, motor boats and tractors that may not receive daily or even weekly use. The connections are easy to make. Doing the job right requires a little simple math to calculate how many solar panels are needed to charge a battery with a specific amp rating. This article explains how to get it done.
Determine the amp-hour rating of the battery to be charged. A wet-cell battery loses about 1 percent of its amperage per day when not in use. This means the solar panel each day will have to supply 1 percent of the battery's total amperage to maintain full charge. For example, a solar panel must be capable of producing 0.5 amp-hours of energy per day to maintain the charge on a 50-amp battery. But solar panels are rated in watts, so some simple conversion math is needed.
Connect the negative wire of the solar panel to the negative terminal of the battery. here
Connect the positive wire from the solar panel to a battery cable with a fusible link between the battery and the solar panel. This will help prevent a fire or battery explosion in the event of a short in the wiring. more
To wire solar panels together for charging a battery, connect the panels in a parallel circuit. This allows you to use several panels of less expensive, smaller power rating together to achieve the same result as a more powerful panel. here
