Whats wrong with using the charger you have already Graham?
Its 20 for two battery's. A lot of the spares come in sets of multiples like they do in the bigger helis.
Thanks TonyYou would charge it as you would the eflight 2s batteries. Look up eflight charging adapter to see what I'm talking about. Here is a picture. The white wire is the only one that doesn't go to the charger, but is for the balance port.
