I'm new to modding and I am messing with the DNA75. I have it wired up in parallel with fresh batteries (VTC4) and it keeps showing check battery. I have checked continuity throughout the board and the board is getting the true 4.2v. Atty side it shows maybe .1 Volts. I have read that there is a fuse in the DNA200 that would blow, causing a similar problem, But I have also read that the DNA 75 does not have this fuse. That being said, I bought the board in working condition in a moonshot box and I de-soldered the connections and re-soldered based on the Evolv website. Not sure where to go from here. Did I fry something?
