Hi guys, I just got the new boxer squonk mod with the dna75c board, it takes one 20700 battery's and after around 50% of using the battery it comes up weak battery, I'm using ijoys 20700s (5 pronged) bought from fogstar in the UK so they are genuine batteries, when the weak battery sign comes up I've seen the mods only firing at around 40 watts, I only vape at 50 watts but you can certainly tell the difference, how can I fix this? Do I need to update it? (highly unlikely as I've only had it 2 days and they are very new to the market, there's only a handful of people in the UK with one) I'm using the dead rabbit RDA at 0.22 ohms. Will an update fix this? Please help.
