Find experienced auto electricians in Beacon Hill

I have a 2003 Track Trailer TVAN camper trailer. The batteries are currently 2x 120Ah but there is lots of voltage drop due to the wiring being old and still the same from 2003. The batteries sit on the outside but I want to relocate them to the inside and change to lighweight/ slimline lithium batteries. It's a basic camper with 4 fixed lights on the inside, a porch light and a number of usb and cigarette lighter points. There is also a box where I can plug directly into the mains but its separate to the 12v system. Although this bix does have voltage meter on it for the batteries. I charge the car using a solar blanket but it doesn't power long enough to keep the fridge going. I essentially want to rewire, put new batteries on the inside and have it all working perfectly. I can supply the batteries

Issue with car radio not turning on loose connection

I’m looking for someone to come assess our front door and see whether a keyless lock would work, if so, suggest a good one that would suit and then install it. When we moved in and got our locks changed the guy said a keyless lock would be difficult and we didn’t really understand why. Budget is $350ish for the lock itself plus labor etc.
