Hi,
If a Brushless motor which uses 20A ESC, and burst current is 25A for 10 sec.

 Then which i have to use, 20A lipo or below 20Aor higher than 20A lipo?   

 And What is that 15C, 20C, 25C,.... in lipo battery? 

 What is that C and mah calculation?

hi,

 if the motor uses a 20/25a, then use an esc of slightly higher rating, like 30 a esc. be sure not to exceed too much as it would burn the motor windings  . and that of c is the discharge value..it indicates the max value of amp draw. it can be calculated as (battery mah*c) .example if 2200mah,20c then 2.2a*20=44a, hence you can draw a max current of 40-44a for best effeciency and higher lifetime.

If i use 44A battery it wont burn the motor. right.?
but the motor is recommended to use 20A ESC.

And How much current a receiver withstand?

(mine is  FS-TH9X 9ch 2.4GHz transmitter & receiver)

 if u mean 44a discharge value then , yes u can use any c value greater than required but not less at all. and receiver i guess 5-6 amps , and it draws 6a only. pls chek the connections in beginers area buddy to get a claer picture

Hi guys,
In RcBazaar, I want to by Odin 2210 KV1200 (Thrust 810 gms) motor  and  Avionic 20Amp ( Output: Continuous 120A, Burst 25A up to 10 Secs) ESC.

Please tell me the suitable Lipo battery for that in RcBazaar.com, I am confused. 

See this, http://www.rcbazaar.com/category/71-batteries-lipo-safe-bags.aspx   

Motor- http://www.rcbazaar.com/products/1483-odin-2210-kv1200-thrust-810-gms.aspx

ESC- http://www.rcbazaar.com/products/806-avionic-20amp.aspx

hi!
 according to the specs at rcbazaar, it requires a 3s 11.1v battery... based on that you can buy any lipo, as long as it outputs 11.1 volts... i would advise a 1300-1500 mah 3s, because the motor has only 800 gms of thrust, and it wil be lighter that a 2200 mah...

hope this helps!

Please note this "any lipo, as long as it outputs 11.1 volts" advice is incorrect, and a little bit of playing russian roulette with your electrical setup.  You can to see what is that wattage for the prop you are planning to use, and make sure there is enough "C" rating and/or mAH to ensure sufficient discharge is supported by the lipo.

Start by reading the related threads in the RC India Gems section.

Hey anikethan i told you before use a batt with 25-30C discharge . And dont ask same type of questions differently, please use one thread to ask all questions

And anwar sir is right before asking any question please RESEARCH yourself. You can use the odin motor you mentioned on a 25-30C lipo but what is your application? You wont get all the 800 gm of thrust on the motor. That is its max efficient capability. The choice of propeller,ESC,batt is crucial to get highest efficiency and thrust .

If we ask everything to others then whats the use of your brain . Dont take offence but if we had guidelines for everything then where will we make our mistakes and learn. So please research on your own and if you dont get required results and dont understand something then ask

@anwar sir, oops... sorry... i forgot about the wattage....
