Batteries in Parallel vs Series, All You Need to Know
When connecting batteries, you have two options: series and parallel. Series connections increase the overall voltage, while parallel connections increase the capacity of the battery bank. In series, the voltage adds up, while in parallel, the voltage stays the same but
Why do batteries with the same voltage have different …
Experts say "current depends on voltage". So, if the voltage is high, current would be high. Agreed; (I = V/R) If the voltage is low, the current would also be low. Agreed -> I = V/R But why then do two different batteries …

Because traditional battery management systems are not designed to measure branch currents of multi-channels, a parallel battery management system (pBMS) was developed to obtain cell parameters and branch currents of parallel batteries.The main features of pBMS include measuring the total current, branch currents, external terminal …
19.5: Alternating voltages and currents
Batteries supply fixed voltages, and circuits with batteries will almost always have DC current. The voltage that is supplied between two of the sockets in a household electrical outlet is "alternating", and leads to "alternating current" (AC), where charges move back and forth, with no net displacement.
