according to futaba there is a crystal or something that prevents one from using a different charger. I have a ACCU-cycle pro series and it won't let me charge by just pluging into the tx. It has a switch for 50--125 Ma.
I'm pretty sure the two connector cables in the picture came with my Accu-Cycle Elite. I know that I had to buy a couple of others for special things, but bottom line is that there are cables available for Accu-Cycles that are marked as pictured. And the picture shows what I use every time I need to charge my Futaba TXs or JRs TXs.
