Honestly, I don't know if it'll push 4x6s @7-8a. I did find out though that the balance current is only 1a per channel, meh. I'll stick to the S6, which can push I believe 15amps combined over 2 channels with 1.6a balance circuit per channel. Good enough for me, charging batteries isn't a race for me.1000watts with PSU, divided by 4? (a 4 Channel Charger??) On A/C doesn't impress me. Price is about right I guess....Price usually equates to he number of channels and the quality/power of the Internal PSU that can support all 4 channels simultaneously.. can it charge (4) 7k-8k mah 6s bricks all at a steady 1C rate?
You would need to own one with a smart display to know what I mean comparing it to an OG 2-line display charger.. The interface and all. In the end they all do the same thing. Charging your lipos. What matters.
