The capacity of the battery pack is the same as that of an individual battery. This assumes that the capacities of the individual batteries are the same. In fact, this is a must. Do not mix and match different size batteries in the same battery pack. Figure 3 shows two 12-volt batteries connected in parallel.
You can think of a battery pack or a power supply like a tank of water filled by a pipe supply regulated with a float valve on the top as shown below. The pressure at the bottom of the tank is dictated by the depth of the water. This is directly comparable to the voltage at the positive end of a battery or power supply.
Batteries in parallel will equalize. This is because when two or more batteries are connected in parallel, the voltage of each battery will remain the same, but the current flow between them will be divided equally. The system’s capacity will also be increased by the number of batteries in the circuit.
Batteries are often connected in series to increase the voltage. This is done by connecting the positive terminal of one battery to the negative terminal of another battery, and so on. The total voltage of the series will be equal to the sum of the voltages of each individual battery.
The battery pack voltage is the same as the voltage of the individual battery. This assumes that the individual battery voltages are the same. In fact, this is an absolute must. Do not mix and match different battery voltages in the same battery pack.
Few things to keep in mind when connecting two different batteries in a series. Since you have two batteries of the same voltage and a compatible connector, connecting them in series is relatively simple. Just connect the positive terminal of one battery to the negative terminal of the other.

Will 2 Batteries in Parallel Equalize? (Here is the Answer)
When two batteries are connected in parallel, the voltage of each battery remains the same, but the total current capacity is increased. This is because the overall resistance of the circuit is lowered, allowing more current to flow. In most cases, connecting batteries in parallel will not cause any problems.

Two Inverters on one Battery Bank
Connecting two inverters to the same battery is easy. But there are some extra calculations and considerations we need to do. C-rate. The C-rate is how fast a battery can discharge. For example, a 12V, 100Ah lead-acid battery has a c-rate of 0.2. 0.2 x 100Ah = 20A. This means you can discharge the battery at 20 amps to achieve a long battery ...

BU-303: Confusion with Voltages
Looking at a Sanyo Eneloop bicycle circa 2010, battery packs no longer available even from Japan (Amazon or Rakuten). The bike has a 250W brushless motor. The battery pack is stated as 25.2V 5.7Ah. Most 250W motors today are 24V. So I''m wondering why they would have used a nonstandard lithium ion 25.2V battery pack... must be 7 cells?
