** Short explanation (series connection)**
In a series connection, batteries of like voltage and amp-hour capacity are connected to increase the voltage of the overall assembly. The positive terminal of the first battery is connected to the negative terminal of the second battery and so on, until the desired voltage is reached. The final voltage is the sum of all battery voltages added together while the final amp-hours remains unchanged.
.........................................................................................................
**parallel connections***
In a parallel connection, batteries of like voltages and capacities are connected to increase the capacity of the overall assembly. The positive terminals of all batteries are connected together, or to a common conductor, and all negative terminals are connected in the same manner. The final voltage remains unchanged while the capacity of the assembly is the sum of the capacities of the individual batteries of this connection.

[@test-193]

He constantly misused Amps with Amphours. Amps is a rating for how much current is actually flowing at a given point in time. Amphours is a measurement of capacity.(how long it can deliver current) For example: the Samsung 30Q cell has an Amphour rating of 3000mAh. (3.0Ah) However it can deliver 15 Amps continuously to your load. See how those are different things?

[@naveenv4227]

Are you referring Ah as ampere or the continuous current draw as ampere,that should be explained clearly because in e-vehicle Ah and max current draw(C rating) both are important. And you explaining the series parallel in 2D plane it would be better if you explain it in 3D matrix.Other wise video is awesome.

[@afsanas8891]

Best explanation 👍

[@joehebbo7047]

Any calculation for c rate?

[@test-193]

The “C” rating is a concept that is applied to batteries based on their Ah rating. 1C = whatever the cells capacity is. (Omit the “hours” part of the capacity rating) For example: an 18650 with a 2500mAh capacity rating would have 1C = 2500mA or 2.5A But a different cell with 1500mAh capacity rating would have 1C = 1.5A Another example: let’s say you have a 1S8P battery. Each cell is rated at 2000mAh. So the total capacity is 16,000mAh or 16Ah. For this 1S8P battery, 1C = 16A. See how 1C is different for every battery? It just depends on the capacity if the battery. Why is this useful? Because some batteries can discharge at 10C, while others can only discharge at 2C. Knowing your cells limits are important. The same goes for charging… you’ll often see recommendations to charge at 0.2C for best results. So you would need to know what 1C is, then divide that by 5 to get 0.2C. Last thing I’ll say is that the “C” rating capabilities of a lithium cell are highly dependent on its chemical composition. Some cell chemistries can output huge currents without burning up. Like the Sony VTC4. Try getting 30amp out of a different chemistry cell and it will likely explode after it heats up to the critical “thermal runaway” temperature.
