Because if the current can flow towards the cells at the right position which are also the negative terminals, why couldn't the current flow to other cell with also the same negative terminal?. That's something that i don't undertand. It something related with the amount of nickel strips that i need to put in the battery pack.No, it is not possible. Why do you think it would?
Can I check , your making this pack ?Because if the current can flow towards the cells at the right position which are also the negative terminals, why couldn't the current flow to other cell with also the same negative terminal?. That's something that i don't undertand. It something related with the amount of nickel strips that i need to put in the battery pack.
I think the TS is simply asking whether there is a preferred direction of current flow in the bridge between two cells connected in parallel and is essentially stating that symmetry argues that if there is any current at all, that it could be in either direction.Hi!. I’ve got a question about this parallel group. It’s possible that at the cells inside the green circle current flows in the direction of the red lines?. If not, why? Thanks!

I think i understand what you are saying. Current could flow in both directions between the first cells at the left side which are connected in parelel because it could be a possible path in order to achieve the positive terminal. But because the same current will flow in one or another direction this both currents cancell each other and no current will flow between this parallel conection. I think that's what you're sayin. Correct me if i'm wrong. If i'm not wrong you answered my question.I think the TS is simply asking whether there is a preferred direction of current flow in the bridge between two cells connected in parallel and is essentially stating that symmetry argues that if there is any current at all, that it could be in either direction.
This is a valid observation, the conclusion being that IF the situation is symmetric, then because the current could flow in either direction, the actual current must, in fact, be identically zero.
But, as others have pointed out, the situation is not always (if ever) symmetric. Whether the current flows one direction or the other depends on the details of the asymmetry. If one cell has a higher voltage than it's neighbor, current will flow in the direction needed to equalize the voltage. There is also voltage drops along the bridging straps and that will result in some current flowing in bridges that, ideally, would otherwise have no voltage drop across them.
It's not a matter of current flowing in both directions and canceling out. Imagine two identical barrels of water that have a pipe connecting them near the bottom. What direction will water flow in that pipe? If the two barrels are filled to the same level, no current will flow. But if one barrel has a bit more water than the other, water will flow from the more-full barrel to the less-full barrel until they are even. Now imagine that there are several barrels connected this way similar to the parallel cells in your battery pack. As water is pulled from the edge barrels, the water drops in those barrels, causing water to flow into them from the barrels they are connected to. This process continues in such a way that water is flowing out of all of the barrels more or less uniformly. But it won't be perfectly uniform, so some barrels will flow a bit more than some of their neighbors, which will prompt some water to flow in the connecting pipes that symmetry would otherwise say should have no effect. It's the same with the cells in this battery.I think i understand what you are saying.

All righ, now we're talking haha. Thanks, you explained it pretty good.It's not a matter of current flowing in both directions and canceling out.

I'm not quite sure because i think water from the pond is also exerting presure upwards.This is a hypothetical question.
Imagine two water tanks feeding water into a pond.
There is an interconnecting branch pipe that lies below the surface of the water in the pond.
Which way does water flow in the branch pipe?
