My Swift 580se caravan battery keeps going flat even with a solar panel fitted it is a new battery the solar panel was built in when the caravan was new I did add a usb plug and it seems to be a permanent live little blue light on all the time but would this flatten a 110 battery ?

assuming its not a dead battery something is draining it.. even new batteries can be faulty..
a usb blue led wont do that..disconnect it at the battery terminals.. see if it still goes flat..
another quick test is connect up just one terminal and touch the other lightly to the other terminal.. if any current is being drawn your will see a spark..
On the new swifts there’s also a master switch on the sargant consumer unit box for the 12v it’s a rectangular black button, make sure that is off as that is meant to disconnect all the 12v supply of the battery is then still going flat, it’s time to play with a multi meter.
a good (as new) fully charged 110 amp battery would need a 2 amp discharge to go flat in two days..
most batteries are not as new but a two amp discharge would be something like a 21 watt car stop lamp bulb..
this is enough to produce a noticeable spark with the terminal touching test..
one thing worth noting is that if the battery has been left fully flat for couple of weeks or so its quite likely to be knackered.. a hard coating builds up on the plates and the battery will not take a charge ever again..
