However, all of this takes time and hence please use this as a first approximation. The battery pack mass is roughly 1.6x the cell mass, based on benchmarking data from >160 packs. However, there are a number of estimation options and always the fallback will be to list and weigh all of the components.
For components in series, the current through each is equal and the voltage drops off. In a simple model, the total capacity of a battery pack with cells in series and parallel is the complement to this.
Increasing or decreasing the number of cells in parallel changes the total energy by 96 x 3.6V x 50Ah = 17,280Wh. As the pack size increases the rate at which it will be charged and discharged will increase. In order to manage and limit the maximum current the battery pack voltage will increase.
The operating voltage of the pack is fundamentally determined by the cell chemistry and the number of cells joined in series. If there is a requirement to deliver a minimum battery pack capacity (eg Electric Vehicle) then you need to understand the variability in cell capacity and how that impacts pack configuration.
To complete the battery pack model, we need to know how different cell capacities combine to give the overall capacity Q. Going back to our analogy at the start of the post, we can see that the capacity of each cell arrangement in parallel will sum up. But how about those arrangements in series?
At 12 volts, it needs 30 amps. But at 24 volts, it drops to 15 amps. So, when you connect batteries in series, always check the device's voltage needs. If you wire batteries in parallel, connect all the positive and negative terminals together. This keeps the system voltage unchanged but adds up the capacities.
Comparing Different Battery Pack Configurations
When we compare different battery pack configurations, we''re looking at three main types: series, parallel, and series-parallel. Each type has its unique power characteristics; series increases voltage, parallel ups the capacity, and series-parallel does a bit of both.

Battery Series and Parallel Connection Calculator
With series-parallel, batteries first link in series, then in parallel, boosting both voltage and capacity. Linking four 12V 26Ah batteries in series gives 48V and 26Ah. However, parallel connecting four 12V 100Ah batteries gives a 12V 400Ah system. Conclusion. Knowing how to connect batteries in series and parallel is key when you design power ...

How many 12 volt batteries to run an air conditioner?
Battery Bank Capacity (Ah @ 12V) = (2400 Wh ÷ 12) ÷ 0.8. Battery Bank Capacity (Ah @ 12V) = 250 Amp-hours (@ 12 Volts) To account for system losses, as a rule of thumb, it is appropriate to round this number up to 300 Amp-hours at 12 Volts. An affordable choice for this battery bank would be 3 of these 12V-100Ah Li-Time batteries. A high-end …
