Parallel Connection. Connecting batteries in parallel adds the amperage or capacity without changing the voltage of the battery system. To wire multiple batteries in parallel, connect the negative terminal (-) of one battery to the negative terminal (-) of another, and do the same to the positive terminals (+).
Most of the current will therefore travel through the bottom battery. And only a small amount of current will travel through the top battery. The correct way of connecting multiple batteries in parallel is to ensure that the total path of the current in and out of each battery is equal.
The basic concept is that when connecting in parallel, you add the amp hour ratings of the batteries together, but the voltage remains the same. For example: 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).
Parallel connection attains higher capacity by adding up the total ampere-hour (Ah). Some packs may consist of a combination of series and parallel connections. Laptop batteries commonly have four 3.6V Li-ion cells in series to achieve a nominal voltage 14.4V and two in parallel to boost the capacity from 2,400mAh to 4,800mAh.
Flow batteries and other chemistries. These are commonly available in 48V. Multiple batteries can connect in parallel without any issues. Each battery has its own battery management system. Together they will generate a total state of charge value for the whole battery bank. A GX monitoring device is needed in the system.
Connecting batteries in parallel adds the amperage or capacity without changing the voltage of the battery system. To wire multiple batteries in parallel, connect the negative terminal (-) of one battery to the negative terminal (-) of another, and do the same to the positive terminals (+).
The number of cells can be varied according to the voltage of a single cell. A Lead-acid battery has a nominal voltage of 2 V, so it requires six cells connected in series to achieve 12 V. The six alkaline batteries of voltage 1.5 V per cell connected in series will give you 9 V.

To wire multiple batteries in parallel, connect the negative terminal (-) of one battery to the negative terminal (-) of another, and do the same to the positive terminals (+).
The number of battery interconnects for one. A 6 parallel battery bank will have 10 interconnects. A 3 parallel battery bank only has 4 interconnects. Each one of those interconnects has to be sound and clean. LA batteries tend to leak, and if your batts are mobile, are subject to movement and vibration.

In a large series/parallel battery bank, an imbalance is created because of wiring variations and slight differences in battery internal resistance. Examples of large battery banks containing 2V lead acid batteries or lithium batteries:
Battery imbalance is when different cells within the pack exhibit different charge levels, capacities, and performances. Most batteries in series combinations feature sealed lead acid batteries. However, most (not all) ionic lithium batteries can also be used in a series connection. It comes down to the Battery Management System or the Protection Circuit …

I allways thought it would be not advisable to put lithium in parallel with lead acid, but the more I think of it, the less crazy it seems. My LA system is 24V based, the 8 cell Winston would be 25.6V nominal. I would source a 3rd party BMS to manage the lithium. Maybe the BMS can take care of the issues - disconnect in low and high side of the daily swings.
