Is their one type of ballancing plug that seems to be the most common? Don't have any at this point. What type is SMC? This seems to be a pain in the you know what. Have they started to make a standered one yet or do most have to have addaptors or something. Thanks for any info.

No, there is no standard and I doubt if there's going to be. Fortunately there is only 4 styles in current use. The most popular is the jst-xh which is also called the Align style plug. SMC uses jst-xh.

Thanks again Duster.

You're welcome!

Its not that expensive to own one of all 4 adapters unless its something like the iCharger 208b - those balance adapters are a little diff than the rest and are more expensive.
