I know this is my 2nd post but got a problem with a dna 30 chip i bought from an ebay seller. I need to find out if its defective or I am missing something. I currently have the dna chip jumped to a dual 18650 craddel that ive wired in parallel. Display powers on and I can move wattage up and down with no problem. But everytime I put an rda on my 510 I get a "low voltage" error. I have tried a build thats at .39ohm and one at 1.95ohm. Both builds are currently working in mech mods. Also, Ive gone as far as pulling everything back out of the hammond box and wiring it together on a table to try to locate the problem. Ive tried only using 1 18650 battery and trying 2 in the craddel. If I move it all the way down to 7watts I can power the 1.95ohm build only. If I move the wattage up at all it pops the low voltage error again. Any ideas?
