You don't typically swap between them, as you would needs different props at the very least when you did.

Typically you want your quad to hover at about 50% throttle. If you do that with 4S then hovering at 3S will be up about 65-70% probably unless you put on larger props.

4S batteries are heavier, but give more power, so on smaller craft 3S is usually used, on larger craft, or if you want to lift payload then you'd run 4S or more

Have you calibrated the Naza's voltage alarm? They are usually a long way out, or _very_ conservative.

The general rule with a LiPo is you only want to drain 80%. I'm betting you're only draining about 20-30%. You can tell this by seeing how much your charger puts back in. Likely way way less than the 80% value of 4000mah

I've never had a Naza, but my understanding is you need to read the battery voltage with a multimeter and then input that number into the Naza software with the same battery connected. From there you can also lower the low voltage warning value until your charger is continually putting about 80% of the battery capacity back in
