Batteries in series combine the voltage while the overall current remains the same as for a single battery. In contrast batteries in parallel will combine the total current capacity while the overall voltage will remain the same as for one battery.

Batteries in parallel voltage. In the parallel diagram were back to 6 volts but the amps increase to 20 ah. Connecting batteries of different voltages in parallel primary disposable batteries they are not designed to take a charge and so the lower voltage battery is likely to. For example suppose two batteries of same rating ie. In this case we can see that 896 mua and 706 mua produced a collective current of 1384 mua or about 216 mua below our expect 160 mua. Such a configuration is called 4s2p meaning four cells in series and two in parallel. For example if a 3v and a 9v battery were wired in parallel the output voltage would be 6v 93 divided by 2 however the current will be total amperage of all batteries in the circuit minus any losses.
The other type of connection is parallel. A 6 volt battery is often three 2 volt cells and a 12 volt battery is usually six 2 volt cells. Laptop batteries commonly have four 36v li ion cells in series to achieve a nominal voltage 144v and two in parallel to boost the capacity from 2400mah to 4800mah. Some packs may consist of a combination of series and parallel connections. In contrast batteries connected in a parallel configuration are able to increase the amp hour capacity of your batteries at the same voltage. The lower voltage battery is not designed to.
When two identical batteries are connected in parallel it will double the current capacity and the output voltage remains the same as a single battery. In theory a 6 volt 5 ah battery and a 12 volt 5 ah battery connected in series will give a supply of 18 volts 6 volts 12 volts and 5 ah. A parallel configuration is not meant to allow your batteries to power anything above its standard voltage output but rather it will increase the duration for which it could power an item at such a capacity. Secondary rechargeable batteries these only fair a little better. 1800 mah 12 v are connected in parallel the output voltage of parallel circuit is remain 12 v butt current capacity becomes 3600 mah. How to wire batteries in parallel.
Parallel connections will increase your current rating but the voltage will stay the same.
