Hi Richard and you can use a standard 50 amp Anderson plug to make up a set of jumper leads and you can use 6B&S twin cable for the leads.
Take care if you intend to buy a set of jumper leads that they have thick enough cable as many of the bought ones, while marked as say 400amp, are usually way too thin.
I do not supply any form of battery monitoring as this is a specialised field and a proper battery monitoring system will set you back a few hundred dollars and needs a lot of work to install.
