FWIW , i made a little pack lastnight ,
4 2100mah rechargeables with charger 25.00
r/s type b adaptacable connector
r/s 1 adaptacable
i had to run the batteries down a bit but after that everything works great for those in question, the adaptacable end has to have the negative side where it says tip,
peace , tonite will be the first trial run for my gear soo we shall see
