I have got F450 Quadcoptor kit  and RCB 6i TX and RX. Now I need to Buy Lipo battery, Can you please recommend shop in Bangalore where I can get good quality Battery and charger.

Thanks

Do you absolutely need it from Bangalore? Can you not order online?

Can you please tell me which model should I buy from online. I am seeing different voltages 7.4V and 11.1V I am in doubt about which one to buy for simonk ESC and 1400KV motors.

7.4V is 2 cell battery whereas 11.1V is 3 cell battery. Now, the 3s(s indicates series) will give more punch than 2s and 4s will give more punch than 3s. But most simon k escs dont support 4s. So I recommend a 3s 2200mAh battery. Go for a higher C rating
