I see that most gimbals come with 3s Lipo 11.1v batteries but Ive learned that LiFe batteries are the better option. My question is which LiFe batteries work as replacements and which charger too? Whats the difference between 3s, 4s, etc...? Whats the connector type on the battery for the controller board? Thanks for helping me figure this out, Im lost in the millions of options on these parts websites!
