... If it's a real iMAX the QC sticker on the belly side will be holographic (changes color with different light angles).
I have the B6AC and absolutely LOVE it
It does all ALL my LiPo, NiMh, and SLA batteries perfectly.
Having the ability to plug it into a wall socket as well as, of course, using a car battery is also very handy.
I used to make my own chargers back in the day because I always wanted more power and better adjustability and
accuracy with delta peak parameters but, with the advent of these latest MCU based chargers, it's hard to beat the iMAX
