Doesn't answer your question about the tekkeon but as far as other options, I have a custom cable that pigtails into 3 Tamiya connectors. I power my mini-me with anywhere from one to three 7.2V RC batteries at a time. I personally love this setup. It's hot-swappable and I have an abundance of RC's at my disposal so I can swap out fresh batteries anytime. Nimh RC batteries are cheap, reliable, fairly lightweight, and found all over ebay. They take an hour to recharge using my digital recharge unit. I run everything I can off of RC batteries.
