I just bought a brand new van with a 330mAh victron battery. I’m trying to get a second to match it. I know this battery has been discontinued does anyone know if there is stock anywhere? I think I’ve mailed all the UK dealers without success 
Change the title of your question… 
what it’s actually about… ‘Looking for Victron battery’… and change the mAh to Ah!!!
Ah not mAh. There are some on ebay but at an eye watering £2,250.
Sadly the Ebay sellers I’ve contacted so far (not the super expensive one I admit) are all “back ordered”.
We got our last delivery from Victron in March and sold the last one in April.
Also Victron doesn’t have any on stock since a few months.
So I would say it will be hard/impossible to find a seller that have some new ones.
