4 FAQs about Can 12v lithium batteries be connected in series to form a 72v battery pack
How to connect 12V lithium batteries in series?
To safely connect 12V lithium batteries in series, the following options should be considered: Customized high voltage protection board: 48V system requires a protection board with a voltage of at least 80V, and the MOSFET selection must match the total voltage.
Can a 12 volt battery pack be mixed?
The capacity of the battery pack is the same as that of an individual battery. This assumes that the capacities of the individual batteries are the same. In fact, this is a must. Do not mix and match different size batteries in the same battery pack. Figure 3 shows two 12-volt batteries connected in parallel.
What is a 12V lithium battery series system?
The 12V lithium battery series system requires stricter parameter matching and a higher specification protection system. When multiple 12V lithium batteries are connected in series, the total voltage increases rapidly, and the voltage resistance requirements for the protection board increase exponentially.
Can I wire lithium batteries in series?
Yes, wiring lithium (LiFePO4) batteries in series is very common and effective, but only under one condition: a proper Battery Management System (BMS) must be used. A BMS is the brain of a lithium battery pack.
