I am Using an Sl6 with a 688 and when the super slot battery runs down it try's to switch to Dc but Dc power value drops from 15.9 to 5.4 and so has to shut down due to lack of power, but the Dc battery is full , so i then have to take the batt from Dc and swap out the sl6 battery. i never had this issue with the previous firmware.
Please help. Thanks!
I didn't find the right solution from the Internet.
