I've got two monitors I am trying to power with a battery. They accept 19V @ 1.3A each, and I'll have them in parallel off a single battery, so they'll need 19V @ 2.3A from the battery. I'm looking at this battery on HobbyKing. The specifications say 22.2V. Can I still use this directly with the monitors? Or would I have to use some resistors to lower the voltage before it got to the monitors?
