Replacing the motherboard


Recommended Posts

I measured the solderings on the board where the battery cables arrive.
Between Gnd and 1 I have a value of 4.20 volts.
Between Gnd and 2 I have a value of 4.20 volts.
Between Gnd and 3 I have a value of 4.20 volts.
Between Gnd and B + I have a value of 12.6 volts.
I attach the values of Escribe.
I sent the original motherboard because she did not read the atomizer after 2 months of use ..
Now this new motherboard replaced in warranty gives me this problem.
All disassembled and assembled by an electronic engineer.
I am disappointed by the Evolv.
I paid the LostVape Triad DNA 250 € 200.00 a year and a half ago.

The device remains on only if connected via USB and batteries inserted.
Only with USB but without batteries the display does not light up but Escribe detects it.
Only with batteries does not give any sign of life.
If I hold down the fire button, the display will appear in sequence: check the battery, check the atomizer.

@AntonioDNA250 It looks as if you soldered the main positive and negative leads from the lipo ONLY to the balance tap area. You also need run the main positive and negative lipo leads to the back -board main B+ and B- pads........ Do you have jumpers, from the tap to the main batt input pads, your picture isn't showing? 

These 2 pads need to be connected to the battery >>>>>>>>>>>>>
