The title says 36v golf cart but the description says input 40v-60v. A 36v lithium could be as low as 30v. Does this work for that?

I'll be hooking this up to a 48v rv battery bank to get 12v power. however, the 48v battery bank charges at 57.6v. will that be too much voltage?

Does the input voltage have to be 36v? The voltage of my lithium ion battery is 41.5v when it's fully charged.

Just opened the package and in the instructions it states: “never charge the battery “. I’m installing on a 36v golf cart, should I be worried?
