Hello, I got a dna75c vapecige creator mod. This week I purchased a couple of VTC5A's (orginal) and flashed appropriate csv to the mod. On the mod battery shows %0(~3,58v), it fires normally without weak battery or etc warning. I took them ut of the mod and put into my ext. charger(xtar vc2 plus). Charger show each battery as %18, which were shown %0 by the mod. Is it made for protecting the batteries by the csv, or it s caused by mod's settings? edit: using vtc5a csv for parallel
