I'm looking into installing a battery charger that was included with the purchase of a Army Surplus forklift. It is labeled to be set up for 480v 1ph. I always thought 480v 1ph was just using 2 of the 3 legs, but the charger is labeled L,N,G. What are they considering N? Maybe I'm just overthinking this.

Something isn't correct. To get 480v you need 2 hot legs not a neutral or 2 hot legs and a neutral...

You are correct that using 2 of the 3 hot conductors is 480V single phase....

They probably just used standard terminal labelling for all of the chargers, no matter what voltage is was setup for.
I agree.

It's like VFDs that can accept either single or 3 phase; they're all labeled L1, L2 and L3 but you'd use only 2 of them for single phase.

Check the wiring diagram & call the manufacturer if need be. It shouldn't matter, but, because of some detail it might.
