My hangar has 110V outlets. I would like to provide a 110V powered battery tender, as well as run my avionics while static. What are the recommendations for this? I’ve looked at batteryminder, but not sure what I am looking at and what would work best for my application. Is there a product that I can mount to the firewall and just plug into for charging and master switch and avionics on for long periods without affecting the battery? Thanks!
