system wire to battery without taking off battery box lid/strap each time. Can I use a Smart Battery Power Station Box without problem? The simple kind that has the posts on the outside, a USB port, and a voltage meter. AND...it is mounted on trailer tongue so when it rains, will it be ok if it gets wet? Looking at the one NAPA sell, MaxiTrac brand. OR...is there a better way ?? Help!
Car, suv or truck can have brake unit at dash. Wired 7pin brakes
or 4 pin no brakes
. Our trailer batteries are usually connected through wall to inside, a converter/control unit. Car or SUV charging system has a unit to protect it while driving and charging with 7 pin.
Solar unit module could be inside and run back out to battery for charging and panels using existing hole.
Breakers are usually just inside the wall at front in boot, then the converter control unit to trailer needs; you could place it there so now rain problems.
Some inside 110v converter units have a charging system built in with shore power being used. It was an option in 1978. Maybe standard now. Do not know if this will affect how to wire solar to charge while camping.
Regular battery maybe a let down for battery life. Even a heavy duty marine deep cycle has its limits. That is why so many upgrade to a newer house battery for the system. Our battery has both posts and wing nut connections.
They make some great batteries that you can checkout later after you figure out how to wire things up. There are some doc in club about wiring things and others that have more knowledge than me about trailers in club but hope this helps
