DNA Advice please

Hey guys.
I have 2 DNA devices now and I love both for different reasons. The DNA chip is great.
That being said I have not adjusted the DNA in any way.
I'd like a bit of advice in what to do please.
One reason I am wanting to do this is because in one mod I am using a VTC5a cell, and if I let it get down to what looks to be around 20% on the DNA display, it shows below 10% on my Xtar charger. I am concerned this could fuck my cell.
So I saw someone mention they had their mod set to use…
