No. Since the internal resistance of dry batteries and lithium batteries is different, ordinary batteries are larger. In order to maintain the same supply current, the internal resistances are added together when used together. However, the internal resistance is currently high for lithium. batteries and weak for dry batteries. Irregular discharge current causes the battery to heat up significantly, which may cause the battery to leak or explode.
The problem of connecting a 3.7V lithium battery and a 1.2V nickel-cadmium battery in series
2 dry batteries connected in series are 3 V. A cell phone battery with a voltage of 3.7 V. can usually be used interchangeably; 4 dry batteries connected in series. The voltage is 6V. It can be used with two cell phone batteries connected in series (7.4V). GeneraHowever, it can be used universally. same voltage. (The above are only suggestions. Please strictly follow the product instructions to configure the power supply during use)
Hello
According to electrical theory, the series voltage direct is: 1.2V+ 3.7V = 4.9V, but since one is a lithium battery and the other is a nickel-cadmium battery, the output voltage is very unstable.
And we all know that even 1.5V dry cell batteries indicate that batteries of different brands should not be mixed, so what you make in this way must have safety risks. I personally recommend not trying it.
Safety first, I hope this can be useful to you.
