Battery configurations

There are two different ways to connect your batteries if you want to use more than one battery at the same time, either parallel or in series and we are going to explain some of the differences here.




Serial configuration


If you choose to connect your batteries in series you will be adding voltages from each battery while the capacity (mAh) and the discharge-rate (C) of the battery will be the same as before. It's not recommended to use batteries with different capacities because this could damage the battery with the lowest capacity.

Example 1


Battery1 = 12 V, 5000 mAh, 30C.
Battery2 = 12 V, 5000 mAh, 30C.

If we connect these two batteries in series they are working together and could be seen as one single battery with the following specifications:
Battery1+Battery2 = 24 V, 5000 mAh, 30C



Example 2


We now have one battery with a lower discharge-rate (C) than the other.
Battery1 = 12 V, 5000 mAh, 20C.
Battery2 = 12 V, 5000 mAh, 30C.

If we connect these two batteries in series they are working together and could be seen as one single battery with the following specifications:
Battery1+Battery2 = 24 V, 5000 mAh, 20C


As you can see, it's the battery with the lowest discharge-rate that decides how much power these two batteries can send from the serial configuration to the ESC.





Parallel configuration



If you connect your batteries in parallel you are adding the capacities (mAh) of the batteries while the other Parallellkopplar man batterier så adderas strömkapaciteterna medan alla andra egenskaper förblir desamma



Example 1

Battery1 = 12 V, 5000 mAh, 30C.
Battery2 = 12 V, 5000 mAh, 30C.

When connecting these two batteries in parallel they are working together and could be seen as one single battery with the following specifications:
Battery1+Battery2 = 12 V, 10000 mAh, 30C



Example 2

Int this example you have batteries with two different discharge-rates (C) and capacities (mAh).
Battery1 = 12 V, 4000 mAh, 20C.
Battery2 = 12 V, 5000 mAh, 30C.

When connecting these two batteries in parallel they are working together and could be seen as one single battery with the following specifications:
Battery1+Battery2 = 12 V, 9000 mAh, ~25C



In general it is most recommended to use identical batteries when connecting batteries and when you want more running time and more power out from your batterypacks it's a parallel connection of your batteries you should go for.
