Sealed lead acid batteries have been the battery of choice for long string, high voltage battery systems for many years, although lithium batteries can be configured in series, it requires attention to the BMS or PCM. Connecting a battery in parallel is when you connect two or more batteries together to increase the amp-hour capacity.
0.52 ohm. A lead acid battery with 12 cells connected in series (no-load voltage=2.1 volts per cell) furnishes 10 amperes to a load of 2-ohms resistance. The internal resistance of the battery in this instance is? 0.52 ohm. If the electrolyte from a lead-acid battery is spilled in the battery compartment, which procedure should be followed?
Lead-acid batteries have a very small internal resistance (typically 0.01 ohms) — that is why they are capable of supplying the high current necessary to start the engine. The internal resistance of lead-acid cells is so small because there are several negative and positive plates in each cell connected in parallel.
The resistance of modern lead acid and lithium-ion batteries stays flat through most of the service life. Better electrolyte additives have reduced internal corrosion issues that affect the resistance. This corrosion is also known as parasitic reactions on the electrolyte and electrodes.
Battery internal resistance varies with SOC. The lower the SOC, the higher the apparent internal resistance. You can crudely calculate it by using ohms law. R= (E/I) It will be in the milliohms for a good bank. Here is a link to a page that has a lot of info on cell resistance. Re: Typical Sealed flooded lead acid internal rsistance ??
The entire resistance encountered by a current as if it flows through a battery from the negative terminal to the positive terminal is known as internal resistance of battery. Battery cells can be connected in series, in parallel and as well as a mixture of both the series and parallel.
Can Lead Acid Batteries Be Used in Parallel for Optimal …
Batteries have a relatively low internal resistance, so if you have one at 11.5v and one at 13v and connect them in parallel you are essentially creating a current unlimited short circuit that could cause one of the batteries to explode or catch fire. For batteries in parallel they must always be charged and discharged together. If ...

Explain the rule of max 3-4 batteries in parallel
Usually there are not enough amps when charging larger banks. If you trickle charge lead acid they sulphate. This tends to happen when there are more in parallel. Cant charge too fast or too slow or too long, or not long enough. You need charge correctly to reverse all the chemistry. Not just get voltages correct.
