Looks as though you both right but for different reasons. Thanks for calling it out. Better safe than sorry and it never hurts to cross-check info.
Their response:
"The BIM will work well for an RV application, I use one personally in my camper van without issue. The BIM is a voltage sensing device that will only only connect and charge if certain voltage conditions exist. It will send a charge for a 15 minute period and then duty cycle for 20 minutes to allow the alternator the time needed to cool.
Mastervolt makes some great products and they work well with our lithium batteries. Either will be a suitable option for your RV. If you'd like to return the BIM please let me know. I'll attach a document that outlines the voltage conditions the BIM will operate".
