Hi Smitty,
There are a lot of guys in Australia using the Schultz charger. Nearly everyone is using charge leads that are around 1 metre in length. I have been using a charge lead of that length for over 18 months with absolutely no problems. You can also solder a standard thin gauge wire with standard plug onto the heavier gauge charge lead to charge your existing RX pack. This does not cause any problem, however due to the thinner gauge wire then you will only be able to charge the pack at a lower rate and it will take considerabley longer.

Russell.
