Hello All,
           I m new to this RC world!!!!! Today I have bought a Aeolian C3542, 1250KV Brushless motor. I gone through its specs but I m unable to understand which battery to be used for the motor. Plz give me the battery type and other details of battery along with the price. Also from where to buy. I m giving the details of motor below.

Rotational Speed:                                1250 (kv) RPM/V
Continuous Current:                             45A
Max. Current:                                      55A
Input Voltage:                                      6 - 14.8V
Max. Efficiency:                                   98%
No Load Current:                                  2.0A
Internal Resistance:                             34m(Omega)
Power:                                                580W
Motor Weight (Motor only):                   140g
Motor Dimensions (Diameter x Length): 35mm x 42mm
Propeller Dimensions:                          10" x 4 "/ 8 " x 7 "/9" x 5"
Input Battery Types:                             NiCd/ Nimh/ Li-po Battery
Recommend Model:                             Airplane

Input voltage is 6-14.8V. So you can use 2S-4S Lipo.

Hi Minesh.
Actually it depends on ur project or purpose. But you should go for High C battery. 3s or 4s  with big capacity 2200 and above.

Thanx swizera and hyd_quads. can u suggest me from where to buy.

if u are a beginner then start with 2200 mah 11.1v lipo . but it will get discharge very soon with 3542 brushless as it consumes a lot ...
if u can then go for 11.1v - 3000 or 3500 or 4200 mah lipo.  cost will be little more but u can consider this as one time investment provided care is taken.

prefer Lipos with 30 C and greater

u also need a controller - ESC - 60 amps minimum recommended  [ prefer integrated BEC or or SBEC or UBEC  ]

C 3542 brushless is very good investment.  [ Aeolian and EMP offers good magnets ]
this brushless can easily handle flying weight of 1.5 Kgs
i have one with me for my models. this is really good but now i use  36-56 1700 KV Brushless capable of handling 1500 watts for my custom models... [ fast wing ]

Thanx pooyan can u give me name of any seller who can provide me this battery and charger. Can you tell me an estimated cost of Battery and charger.

Hi minesh,

In my opinion, you need to choose the battery based on the the purpose you are using It for. Higher the voltage(S value) and/or capacity (C rating) the bigger the battery and more the cost. You might buy a battery with ample capacity , but might be too heavy to use for your application.

So, evaluate carefully before investing. I'm not an expert though just trying to arm you b4 investing.
