Hey guys, I'm building my first mini quad with

DYS SE2205 2300kV motors
DYS XS 30A or XM20A
220 frame

Since I'm a beginner, I decided it would be best to run 5040 props.

However, the problem I'm facing is that of which battery to select. RCHLipos has 1300 mAh batteries at 65C, 75C and 80C ratings. I am not sure which ones to get. I know that for 5040 props, the 65C battery would be enough, but what if I wanted to run triblades in the future? I am not sure whether any of those batteries would be able to run any props with current draws over 20A, and so would it be better to get 20A ESCs?

Very confused as to what the current draws will be and which battery is the best bang for my buck.

Would appreciate some advice, thanks.

I'm not good at this but I'll try to answer the best I can.. You need minimum 45c batteries no matter what props you run. Also regarding esc I'm currently running cobra 2204 2300kv lb20a with dal 5045x3 props. I'm thinking I roughly pull about 60-70amps. Go for the new blheli_s esc.

for escs got with the XS series rather than the XM series.
Tattu's are very durable! They will work in any shape. One of my battery is thrashed badly but still it works! Bonkas offer a lot of power and punch! Overall there isn't much difference between the Bonkas and Tattus, both are great! I use both of them!

Woah, you only draw 60-70 amps with triblades? That means the 1300 mAh 65C bonka batteries would be fine right?

Was awaiting your reply! I'm getting these: http://www.rchyper.com/dys-xs-30a-3-6s-lipo-blheli-s-electronic-speed-controller.html
They look good right? Also, would a 65C 1300 mah battery be enough to supply dual/triblades on a 2300kv setup?



By the way, can both of you guys recommend what prop size (5030, 5040 or 5045) I should start with and what brand to get?

Pretty much all the C ratings in the industry are inflated. I'd say the only difference between the 65C and 75C packs is the QC process. The best quality cells are labelled 75C and the next best are labelled 65C. I use the Bonka 75C but I haven't tried the 65C so I can't really compare. However, I haven't felt all that much difference between a Tattu 75C, Dinogy 65C and Bonka 75C. Now that Ive got an OSD with integrated current sensor, I'lls ee if I notice any difference in max current draw/ voltage sag, I believe the 80C packs are a different chemistry, supposed to contain graphene. The Turnigy Graphene packs are known for their extremely high cycle life, good discharge rate, high charge rates and resilience to overdischarge. I'm not sure if the Bonka Graphene packs have all the same benefits

You probably don't need a 30A ESC, even if you go with more aggressive props like bullnose triblades as most 20A ESCs on the market can easily take 30A burst, and you won't hit the kind of current draw you see in bench tests in the air as the motor unloads in flight. However if the size and weight difference aren't too much of a concern, then 30A may give you some more peace of mind.

The SE2205 have plenty of torque so you could spin some pretty beefy propellers like the DAL T5045BN (triblade). However, if you want something a little tamer, then you could probably start with two blade 5040s. Both DAL and KingKong make some very durable props that will help you out when you're starting off.
