This is absolutely not possible.
Their internal resistance and capacity are different.
Suppose one battery is 10AH and the other is 1AH . When used in series, they will be A. current discharge, after 1 hour discharge, the power of 1AH battery is exhausted, and the capacity of 10AH battery is still 9AH. Understand!
Absolutely not, it will burn
2. Battery Capacity: The unit of measurement for battery capacity is actually the total number of electrons in the battery that can be released for external use. 1mAh=0.001 Ampere*3600 seconds=3.6 Ampere seconds=3.6 Coulombs For example, a 1000 mAh battery can provide 250 mA constant current power for 4 hours.
The corresponding relationship between the open circuit voltage of lithium-ion batteries and the battery capacity is generally as follows: the percentage is the remaining capacity of the battery,and the right side is the open circuit voltage (OCV) of the corresponding battery.
100%----4.20V 90%-----4.06V
80%-----3.98V 70%----- 3.92V< /p>
60%-----3.87V 50%-----3.82V
40%-----3.79V 30%- ----3.77V< /p>
20%-----3.74V 10%-----3.68V
5%------3 .45V 0%------3.00 V
3.11V/15.6A=0.7 ohm
3.7V*3/0.7= 15A
However, after series connection, the current remains unchanged, only 2A, and it will burn
4. Generally used in mobile phones, lithium cobalt oxide battery, which is only 1000MAH and the maximum is 1350MAH
The battery of the parallel connected POS machine can reach 5000MAH

C means Capacity: For example, if the capacity of a battery is 800MAH, 1C is 800ma,
If the capacity of a battery is 1000MAH, 1C is 1000ma, and 2C is 2000 mA
General lithium phosphate batteries are used for large currents, such aselectric vehicle batteries
