JacobEvolv Posted May 9, 2019 Report Share Posted May 9, 2019 BlackMamba50, I noticed that the USB power is only at .8 watts. Have you tried a different charger ? Link to comment Share on other sites More sharing options...
BLACKMAMBA505 Posted May 10, 2019 Author Report Share Posted May 10, 2019 now i'm hearing it might be a blown fuse. after it charged last night the battery almost dropped to zero for i don't know what reason. though the usb current is now higher at .23 it's still low. and i've let it sit charging for hours and its still stuck at zero percent. even with usb battery recovery. the usb power is at 1.1 now. do you guys think it's the fuse?

dwcraig1 Posted May 10, 2019 Report Share Posted May 10, 2019 Not the fuse. Charging rate is probably going to be low using USB recovery till it gets to above 2.5 volts per cell. Link to comment Share on other sites More sharing options...

retird Posted May 12, 2019 Report Share Posted May 12, 2019 Check the cell balance tap pinouts against the pin outs of the li-po you put in...and are all connections still solid??? https://downloads.evolvapor.com/dna250.pdf 1 Link to comment Share on other sites More sharing options...
