In theory, a 6 volt 5 Ah battery and a 12 volt 5 Ah battery connected in series will give a supply of 18 volts (6 volts + 12 volts) and 5 Ah. A 6 volt battery is often three 2 volt cells and a 12 volt battery is usually six 2 volt cells. Therefore, all you have done is connected nine 2 volt cells together to get 18 volts … so what''s the ...
By connecting all of the positive pads together with one wire and the negative ones with another, we essentially connected all of the battery cells in parallel where the voltage of the pack will still be the same as one cell but it''s capacity increases.
I know this question is two years old but it still pops up on research. I just wanted to add something from my experience with this: If you take an Enerpower HTCFR18650 for example datasheet you see that the maximum voltage isn''t 4.2V but 3.65V +/- 0.05V. While this technically is a little bit above the absolute maximum rating of the ESP32 (3.6V), in a non …

An electric battery is an energy storage device comprising one or more electrochemical cells. These cells have external connections used to power electrical devices. When providing power, the battery''s positive terminal serves as the cathode, while the negative terminal functions as the anode.
$begingroup$ I modified an old smartphone (Oppo Find 5) to work directly from a USB power supply by connecting the battery contacts to 5 V directly or via a diode to lower the voltage slightly. That works for that model phone. There is no guarantee that this will work for other phones as well! In the end, you will just have to try what works. Some phones need a lot …

Get a battery holder to make the experiment more portable. Purchase a battery holder for the size of battery that you are using in your circuit. Place the battery inside the holder, then connect the 2 electrical wires coming out of the holder to the side and bottom of the lightbulb.
If you just make an Atmega 328 on a piece of stripboard and use its internal 8MHz clock you can run off two alkaline cells (3v). I suspect a paid of AAA cells would power it for a long time. And you can get some very small LiPo cells (3.7v) that could also power it and should be even lighter. Indeed a 3v coin cell may be sufficient.
The way the power capability is measured is in C''s.A C is the Amp-hour capacity divided by 1 hour. So the C of a 2Ah battery is 2A.The amount of current a battery ''likes'' to have drawn from it is measured in C.The higher the C the more current you can draw from the battery without exhausting it prematurely. Lead acid batteries can have very high C values (10C or …
