We are going to be in the van tomorrow with hook up.
We have a leisure battery but nothing exotic (no willington or what have you)
If we are hooked up and have the cricket on the radio will it drain the main battery or will the hook up keep it topped up?
You see the radio in the van has LW and our portable doesn't, our DAB portable only lasted a few months

If I listen to cricket and result in a flat battery I will NEVER hear the end of it.

Cheers
Sarah
