VapingBad Posted February 4, 2017 Report Share Posted February 4, 2017 That would be right if any of the cells are almost full, the Wh were set very very low or the board was hot. I would check your cell levels first, then put USB voltage and current and board temp on the charge screen optional fields as if the USB voltage drops too low it can only pull moderate current from the supply, it also helps selecting the best cable and supply.

hs107 Posted February 4, 2017 Author Report Share Posted February 4, 2017 Wh are analiesed with Escripe to the right level. all cells are at 3.6V, diffrent DNA with same Lipo works fine with this setup and charge normally. Link to comment Share on other sites More sharing options...
VapingBad Posted February 5, 2017 Report Share Posted February 5, 2017 What is the USB voltage on the DNA screen? Link to comment Share on other sites More sharing options...
hs107 Posted February 5, 2017 Author Report Share Posted February 5, 2017 so when i plug it to the PC (Escripe running) it shows 5.05V, Escripe says the samewhen I plug it to a wall mount adapter it shows 5.33V Link to comment Share on other sites More sharing options...
VapingBad Posted February 5, 2017 Report Share Posted February 5, 2017 A long shot, is the board temp showing a high value, occasionally the thermistor fails and false high temp reading would reduce charge current. Link to comment Share on other sites More sharing options...

VapingBad Posted February 7, 2017 Report Share Posted February 7, 2017 Looks like a bad thermistor unless it is really -40 F where you are, if so the board needs replacing, as it a 250 it will be under warranty. Link to comment Share on other sites More sharing options...
