I bought a Quanum Nova from HK. It came with a 2700 20-30c Turnigy battery. This battery does not exist on the HK website at any location. It is very small for its capacity. It measures 95x34x27. There is nothing even close to this size and capacity on the site. Unfortunately the QN won't take anything much bigger. Does anybody know where I can find a battery that will fit and have similar capacity?
