If you’re charging typical 4s packs you need more power per channel, to reduce the charge time for each battery. The AC powered quad charger only has 50 watts per channel if I’m not mistaken, that’s not enough.

Hitec does have a X4 Eighty that gets closer to what the typical 4S needs, 80W per channel. Does require a power supply, DC only.

But even better would be a more powerful dual channel charger, there are several brands that have a 200W – 10 amps per channel charger (or larger). Then charge times come way down, especially if your lipos are rated for higher than 1C charge rates and you are comfortable with that.

FYI, it’s a lot better for your lipos life and performance if you charge as you need them, instead of ahead of time. Lipos don’t like sitting at full charge, can lead to puffing and reduced performance, especially if there are temperature changes. A good sized dual charger makes it fairly easy.
