What does it mean to connect batteries in parallel?
For more information on wiring in parallel see Connecting batteries in parallel or our article on building battery banks. The basic concept when connecting in series is that you add the voltages of the batteries together, but the amp hour capacity remains the same.
How are batteries connected in a series connection?
Batteries in Series Connection (Series Battery Pack) Batteries are connected from terminal to terminal in a way that positive (+) terminal of one battery is connected with negative (-) terminal of other battery and negative terminal (-) of one battery is connected with positive terminal (+) of other battery. See the diagram for more idea:
Can a 4.5 Ah battery be wired in parallel?
two 6 volt 4.5 Ah batteries wired in parallel are capable of providing 6 volt 9 amp hours (4.5 Ah + 4.5 Ah). four 1.2 volt 2,000 mAh wired in parallel can provide 1.2 volt 8,000 mAh (2,000 mAh x 4). But what happens if you wire batteries of different voltages and amp hour capacities together in parallel? This is the big “no go area”.

In a series connection, the + contact of a battery is connected with the – contact of another battery, thus forming one “new” battery. In the two ends of this battery (from now on called battery bank) there are one + and one – contact unconnected. These two contacts are the positive and negative pole of the bank.
