If it is only rated down to 2S, this is lipo voltage, not lion - some ESCs will cutout when getting close to 6v. If you are using a 1-2S or 1-3S ESC then you would not need to worry.

My AIO is iFlight succex-d whoop V3 and it is rated as 2S-4S.

If you are flying 2S, you ideally want a 1-2S AIO or 1-3S AIO, such as the BetaFPV 12A, HM Various or the Darwin 1-3S AIO. Be aware that specific VTX tend to work lower than others. Watch LR / Li-ion vids on YT to get a handle on the best parts to use.
