I just bought the superbrain 959. Im going to using it to charge 6v 1100-1400 receiver packs. Im pretty sure the amps should be around .5 - 1 but what about the peak threshold setting? Also do these 6v packs come charged, because as soon as I hooked it up to the charger it read at least 6v and kept going up a little at a time. So a fully charged 6v pack when fully charged will show up with how much higher on the chargers digital read out? thanks
