Im new to electronics and Im wondring if its possible to make a battery pack like this to get more amps or do i need to have 4x2 batteries and combine with same amount of volt?
Sincerely,
Adam
No, the voltage that the four seried batteries will give would never be equal to the voltage of the single one (this is true for two single "nominally equal" batteries).
The consequence is that the higher voltage battery will charge (if rechargeable) the other with an unlimited courrent. Dangerous (at least non functional).
In certain circumstances (High currents, no efficiency considerations) you can equalize batteries by placing serial resistors to each one, but I do not recommend it.
Regards.
You need two banks of 4 if you want to put them in parallel - when you parallel things, they'll all have the same voltage on them (this is also why they always say to use all the same brand of batteries in the same state of charge on consumer electronics).
So putting a 1.5v battery in parallel with a 6v stack of batteries, they will try to reach a single voltage. This would probably drain the batteries in the stack as they futilly tried to charge the third battery to four times it's operating voltage, and really kill that poor single battery. Depending on the batteries, they may just get hot, or they might smoke, catch fire, or even explode.

That really should be self-evident.
