Hey Rick,
The Duralite (turbine pack) came with 16ga leads. You have the option of 16 or 18ga. It has a seperate charge jack that passes through a special charging circuit to avoid overcharging. This lead is a typical JR/Hitec plug. I did splice the main lead and add a deans plug to disconnect the pack during charging since Jetcat recommends this practice (I also already had a deans plug on the ECU side from the nicad pack that was orig. installed). Certain types of chargers can damage the ECU during the charge phase, since I was not sure if the lithium type charger is a type that can damage the ECU I decided it would be best to unplug during charge. I have manged to get 8 starts/flights on this 3600 mah pack, more may be possible but have yet to fly the plane more than this in a single flying session (I have three planes flying). After 8 runs the pack was still showing 7.4 volts and my typical flight time on the EF is 9 min and 12-14 min run time! No regulator is needed with the Jetcats but one may be necessary with other brands of turbines depending on ECU input voltage.
Feel free to contact me if you have any further questions...
Regards,
Todd
