I have a Hitec X2 AC Plus Black Edition Charger / Discharger Power Supply. I can not find anywhere if this charger with work correctly if an external power supply is connect to the dc output/input plug. My thinking is that by using an external psu I can bypass the 100w inside the unit to allow for faster charge time when two batteries are connected. Or am I stuck and will need to step up to somthing else. Any information will be greatly appreciated. Thank you

Yes you can use a power supply up to 200 watts and between 11-18 volts.

Dual Input and Power Distribution:
The X2 AC Plus Black Edition has a dual AC/DC input comprised of AC 100-240V
and DC 11-18V. In DC mode, the power of each channel is 100W with an overall
power of 200W. Power distribution is supported in AC mode. For example, if
Channel A is 70W and Channel B is 30W, total power is 100W.

Awesome thank you I saw that just wanted to double check. I guess a follow up to it all is if I wanted to do a psu build using a dps-600pb server type psu, to be correct in assuming that I would be over the wattage threshold. Thank you again.

A power supply capable of delivering more power then the charger can handle is a good thing.

Awesome thank you for the quick response. Sounds like I’m off to ordering some materials and time to get more power.
