Dear all,
I have 6 cell / 22.8v 4500 mah battery.
Can i use then or strictly 4s batteries?

What are you connecting your battery to? If it's ModalAI's APMv3, then the datasheet can be found [here](https://docs.modalai.com/power-module-v3-datasheet/#specification)

From the datasheet:
LIPO range 2S-6S [2 cell (6.4V min, 7.4V nom, 8.4V max) 6 cell ( 19.2V min, 22.2V nom, 25.2V max)]
Note: Absolute max voltage of design is limited to 28V due to the INA231 current sense IC’s.
