3. Battery bank wiring
Current will always choose the path of least resistance. 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.

20.1: Current
The direction of conventional current is the direction that positive charge would flow. Depending on the situation, positive charges, negative charges, or both may move. In metal wires, for example, current is carried by electrons—that is, negative charges move. In ionic solutions, such as salt water, both positive and negative charges move.

Battery pack
A battery pack is a set of any number of (preferably) identical batteries or individual battery cells. [1][2] They may be configured in a series, parallel or a mixture of both to deliver the desired voltage and current. The term battery pack is often used in reference to cordless tools, radio-controlled hobby toys, and battery electric vehicles.
Battery Pack
A battery pack is a combination of cells connected in series and parallel for the desired operating voltage and current ratings. These packs having different designs involving electrochemical, mechanical, control and thermodynamic principles.

19.2: Electric Current
One half-cell includes electrolyte and the anode, or negative electrode; the other half-cell includes electrolyte and the cathode, or positive electrode. In the redox (reduction-oxidation) reaction that powers the battery, cations are reduced (electrons are added) at the cathode, while anions are oxidized (electrons are removed) at the anode.
Confusion between positive and negative terminals of a battery
Outside a battery, current flows from its positive terminal to its negative terminal. Inside the battery, to stop charge building up, the current must flow the rest of the way round, from the negative terminal to the positive terminal. This flow is driven by the chemical reactions in the battery. In an electrolysis cell the current flows ...

Batteries Part 2
When a battery cell is open-circuited (i.e. no-load and R L = ∞Ω) and is not supplying current, the voltage across the terminals will be equal to E.When a load resistance, R L is connected across the cells terminals, the cell supplies a current I which causes a voltage drop across internal resistance R INT of the cell. ...
