Consider the example of two batteries connected in parallel: Battery A has a voltage of 6 volts and a current of 2 amps, while Battery B has a voltage of 6 volts and a current of 3 amps. When connected in parallel, the total voltage remains at 6 volts, but the total current increases to 5 amps. Advantages and Disadvantages of Parallel Connections
Yes, parallel batteries "can" supply twice the current when the load is less than the ESR of the battery. ( As shown above, for short circuit current, it is twice.) But otherwise, when the load is equal to battery ESR, the current is the same. With series cells it greater when the load R is higher than ESR, the higher V/R produces a higher current.
You could connect 10 car batteries in parallel and it would still only draw 3A in total because that's all it needs (in this case, each one would supply 0.3 A if they are identical) If the batteries are identical, one battery provides half the current. If they are not identical, e.g. one battery is dead or missing, full 3A.
To charge three batteries in parallel, you will need a three-battery charger. Connect the positive terminal of the charger to the positive terminal of the first battery, and connect the negative terminal of the charger to the negative terminal of the third battery.
When using batteries in parallel, it is essential that the batteries are of the same Ah. Otherwise, connecting batteries of different Ah in parallel will result in the higher Ah battery being overworked, and the lower Ah battery not working to its full potential. To prevent this from happening, diodes can be used.
Definition and Explanation of Parallel Connections In a parallel connection, batteries are connected side by side, with their positive terminals connected together and their negative terminals connected together. This results in an increase in the total current, while the voltage across the batteries remains the same.

However if one cell fails to open circuit or very low internal resistance, current will now be flowing mostly through that one cell. Say the pack normally gets charged at 1C rate, now that cell is getting 3C rate. If there are 20 cells in parallel, now it''s 20C rate. The more cells in parallel, the more current can flow to the most unbalanced ...

How many amps between batteries that are wired in parallel?
If the batteries are identical, one battery provides half the current. If they are not identical, e.g. one battery is dead or missing, full 3A. If you connect two batteries together that are unequally charged, e.g. one full and one empty, any arbitrarily large current would flow to equalize the charge levels. Prepare with good margin and fuses.
