Why is the voltage of the battery pack connected in series less than 3V
When connected in series each battery maintains that constant voltage across its ends and hence they add up. But If connected in parallel, they remain the same by definition. But this is not an answer unless I explain why the voltage across the ends of a battery remain same. And for that we need to look inside a battery. - Download [PDF]

$begingroup$ How do all areas of a pool fill evenly from bottom to top? Same thing. There are no barriers in different sections of a pool. Same thing with cells connected in parallel. A cell is like a square bucket where the walls between buckets disappear when you put one up against another.

The volume control you are using has an "A" audio taper but the LM4952 also has an audio taper. Then use a "B" linear taper. The NE5532 is not needed and use 1uF film capacitors feeing the LM4952. The lithium battery cells will be damaged if they discharge less than 3V each, add a voltage monitor/disconnect circuit. $endgroup$ –

You specified "in parallel" which is less usual and less controlled in some respects. The answer below applies more to series connected cells but has implications or parallel connection. One possible mechanism for unprotected cells is for one cell to be lower in voltage than the others.
Voltage in series circuits | IOPSpark
The sum of the voltages across the bulbs/resistors must equal the battery voltage. This follows from the energy description. The power in must be equal to the power out.. The energy shifted from the chemical store of the battery must equal the energy shifted by the charged particles as they pass through the bulbs/resistors.

What is the minimum required voltage for charging a 3.7 V Li-ion battery?
Technically the minimum amount of voltage for charging will be anything above the current state of charge. But that''s probably not the answer you''re looking for, from Lithium-ion battery on Wikipedia:. Lithium-ion is charged at approximately 4.2 ± 0.05 V/cell except for "military long life" that uses 3.92 V to extend battery life.
Why is a laptop power supply output voltage different from its battery …
Normally, the adapter output voltage is higher than that of the battery. In my laptop''s case, the output voltage of the ... So in this case a nominal 10.3V battery could be charged at over 6 Amps with the same 65 Watts if the battery can handle that amount of charging current safely. ... then 10% minus from 19V will be 17.1V. This is lower than ...
BU-303: Confusion with Voltages
The 3.70V/cell rating also creates unfamiliar references of 11.1V and 14.8V when connecting three and four cells in series rather than the more familiar 10.80V and 14.40V respectively. ...

How to Connect Batteries in Series
One of the most common battery circuit topologies is to connect batteries in series. This means placing two or more batteries end to end with a metallic connection between them, allowing the voltage supplied by each section (cell) to add (series), creating an even greater voltage than a single cell.
Why do batteries in series add up voltage?
When you connect a third battery in series, there is three times the amount of work done on each electron. The current, however, stays the same as for a single battery because …
GPIO output less than 3.3V
There are also special constant current drivers that make using LEDs and similar devices even easier. I cannot agree on the higher than 3V3 supply part though. As long as the supply voltage is higher than forward voltage of the LED and can source sufficient current it''ll work with the appropriate current limiting resistor.
Battery voltage drops from 12.3V to 11.2V in 5mins
That''s not enough to drain a healthy 12V automotive battery from 12.3V to 11.2V in only five minutes. Instead what''s happening is that when the battery is charged, that includes "surface charge", which gives the illusion of a higher charge on the battery than there really is. (See e.g. What is surface charge and how does it affect battery …
Parallel vs. Series: Connecting Cells To Build A Battery
Combining Series and Parallel Connections. Since a parallel connection will compound the amperage of a battery and a series connection will compound the voltage of a battery, we can arrange cells in combinations of series and parallel to achieve our desired voltage and amperage. Returning to our 12-volt example: we can connect four 3.2V …

Battery configurations (series and parallel) and their protections
A Lead-acid battery has a nominal voltage of 2 V, requiring six cells connected in series to achieve 12 V. The six alkaline batteries with a voltage of 1.5 V per cell connected in series will give you 9 V. If the device needs an odd voltage, for example, 10 volts, then three Li-ion batteries can be connected in series.
When you connect two batteries in series, why doesn''t the …
When you connect the plus from one battery to the minus of the other, you have a short of the second kind. However, there is no current flowing, as this requires a circuit —a closed loop— so obviously, B does not imply A. As soon you connect the plus from the other battery to the minus of the first also, there is a closed loop, and your short …
