What you have is two sets of two batteries each connected in parallel. Then those two parallel connected sets of batteries are connected in series by a single wire connection.
In this type of arrangement, we refer to each pair of series connected batteries as a "string". Batteries A and C are in series. Batteries B and D are in series. The string A and C is in parallel with the string B and D. Notice that the total battery pack voltage is 24 volts and that the total battery pack capacity is 40 amp-hours.
There are many ways to connect a group of batteries in both series and parallel at the same time. This is common practice in many battery power appliances, particularly in electric vehicles and large UPS systems where the battery packs require large voltages and amp-hour capacities.
You can use up to two of our Lithium 12v / 24v batteries in series and up to four in parallel packs. You should arrange your charge setup so that each battery in the pack is individually connected to a charger. Batteries should be of the same model, and purchased together at the same time, to ensure they have similar performance characteristics.
The number of batteries you can wire in series, parallel, or series-parallel depends on the specific application and the capabilities of the battery bank you are building. For details, refer to the user manual of the specific battery or contact the battery manufacturer if necessary.
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.
