Evolutio battary problem

  • hello.

    I bought a second hand evolution.

    I programmed the battery type (lipo) and the output voltage (7.4).

    After the unit is turned on, the green L.E.D for batterys 1 and 2 on the backer come on and after about 30 seconds to a minute all the L.E.D for battery number 1 turn on.

    Needless to say, the battery is good and I even tried to switching between the batteries and encountered the same problem.

    Please help.
