You can get it at hobbysea.com 2200mAh 3S 20C for 830/- from
Hobbysea or from
QuadCoptor.com for 750/- (Out of stock) or
the hobbyshop for 1160/- (poor buyer's review in forum)
However, I will say to take zippy or other having more C Capacity from
RCBazaar, RCDhamaka , or
Aeroworks.in . You can wait for hobbysea, RCElectro and some other stores till 27th of month for update of stock. Though Price war is going very close competition, found hobbysea is the cheaper than other while transportation cost considered.
Hope it will work.
