Gogoana et al. focused on the matching of the internal resistances of parallel-connected lithium-ion battery cells. The measurements were done with two LiFePO 4 battery cells connected in parallel . The used set-up is described without any explanation of the wiring, the additional impedances, or the used sensors.
Lithium battery parallel should pay attention to the consistency of the battery, because the parallel lithium battery with poor consistency will not charge or overcharge during the charging process, thereby destroying the battery structure and affecting the life of the whole battery.
When batteries are connected in parallel, the voltage across each battery remains the same. For instance, if two 6-volt batteries are connected in parallel, the total voltage across the batteries would still be 6 volts. Effects of Parallel Connections on Current
The parallel-connected batteries are capable of delivering more current than the series-connected batteries but the current actually delivered will depend on the applied voltage and load resistance. You understand Ohm's Law, but the "parallel batteries supply more current" statement should really be "parallel batteries CAN supply more current".

A series connection involves linking batteries end-to-end to increase the total voltage while keeping the same capacity (measured in milliampere-hours, or mAh). For example, connecting two 3.7V 100mAh lithium cells in series will yield a total voltage of 7.4V, but the capacity remains 100mAh. This type of connection is ideal when your device requires a higher …
MY own personal rule is two batteries, 150% current of one battery. So with two batteries each capable of 100 amps, with 2 in parallel, you can pull 150 amps, so even if there is a 50 amp difference, the high battery is only at 100 amps, and the low one is providing the other 50 amps. Go to 4 batteries, and now you should be safe pushing 225% ...
However, parallel connections often provide longer runtime by increasing total capacity (Ah). For instance, two 12V, 100Ah batteries in parallel result in 200Ah, which can reduce the depth of discharge (DoD) and potentially extend battery life, with lithium-ion batteries achieving up to 2,000 cycles at 50% DoD compared to 500 cycles at 80% DoD.

The pressure remains the same, but you now have double the water. Same as the water tanks, let''s consider you have lithium batteries, each with 12 volts and 100 amp hours. Connect two lithium batteries with 12 volts in parallel, and the total voltage is still 12 volts, but the total capacity jumps to 200 amp hours. It''s like doubling the ...

In a series connection, batteries are connected one after the other, creating a chain-like structure. This connects the positive terminal of one battery to the negative terminal of the next, resulting in a cumulative increase in voltage.
