Hey out of these three which one will give the most flight time on my iFlight Chimera 5 HD?
Thank you in advance!

For some reason it didn't post my picture, the three batteries were: 1. 4S Tattu R-line 2000 mAh 120c
2. 4S Tattu R-Line 1800 mAh 120c
3. 4S Tattu 3700 mAh 45c

  I’d choose the 4S 2000 over the 4S 1800.
  20 extra grams for 200 more mah is worth the extra weight and you probably wouldn’t feel the difference while flying.
 The length of the 4S 3700 may be too long and the extra 150 grams you will definitely feel when flying.
 
  Also trying different batteries can get a bit expensive and there’s always a risk it may not work as planned.


  I like the 4S 2000 for it’s got plenty of amps,decent flight time and I can use it on 5”,6” and my 7” quads with 4S rated motors.
When I started fpv I used 4S motors on 5” and 4S 2000 Tatuu packs.Then I built a 6” and used the same battery and got longer flight times using 6” and more speed too.I built a 7” and they work good on it too.
   
  Tough choice on the 4S 3700.
 370 grams is a heavy battery and the extra weight could cancel out the extra capacity.

By their recommendations, they claim 22-24 minutes of flight on a 4S VTC6 Li-Ion pack. Those tend to sit at around 200g and pack 3000mAh. Would assume that they're making that claim by merely hovering the whole time. Naturally, you'll need to be careful with that choice as you'll have an amp limit of 15. Probably not a bad idea to dummy load it and fly a LiPo to test it beforehand if possible. Alternatively, if you aren't bothered by a 300g pack, Molicel P42A cells will give you 4200mAh and an amp limit of 45.

Of course, it really depends on how far you actually want to go. The 2000mAh LiPo will easily take you to 2-3 miles out, but still leave you able to rip around like most people would do.
