So I’m mildly confused about how everyone calcuate their battery capacity. Saw someone said that they have a 30q 10s6p or something and they have 18Ah.
Let’s bring it back to the basics. Ampere measures how much electrical charge move through a surface thus it is collums/seconds. And battery are rated in [mAh] = [collums].
Let say we only use 30q.
If u have 1s1p (only 1 cell) you have 3000mAh = 3Ah.
If u have 10s1p ==> 30 Ah.
If u have 10s4p ==> 120Ah.
Am I wrong or are ppl miss labelling their battery.?
Sounds like the confusion is AmpHour(Ah) is not a valid measurement of energy, since it depends on voltage. The closest unit of energy you can convert to from Ah is WattHour(Wh), which you get by multiplying the voltage with the Ah. So when you get series connections, you increase Voltage, which increases Wh, but not Ah. While adding parallel connections you increase Ah but not Voltage. In both cases you do increase overall energy, but only adding parallel connections gets you that conventional Ah number
In a series circuit, the current through each of the components is the same, and the voltage across the circuit is the sum of the voltages across each component.[1] In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component.[1]
Your understanding of electricity is a little off. Most of this stuff would be considered college level physics. Though if you want to know the why behind why it functions this way, well that’s a whole nother level, and my question for you is why do you need to understand it to that level of detail.
