The more I searched throughout the internet the more confused I became.
Imagine I have 13 batteries, each of them 3.7V, 20A, 3000mAh and I want to power 1000 W 48V DC electric motor.
If I connect the batteries in series I will have 48V but only 3000 mAh. If I connect them in parallel I will have 39 000mAh, but only 3.7V
However there are a lot of current being unused and I figured I could use some step-up DC-DC voltage regulator, but I am unable to see how they work and what kind of it will I need. I assume they will decrease the current, hence decreasing the capacity in order to increase the energy.
What voltage regulator is best for this, how much of the amps/mAhs will it affect?
