Suggested Battery HSS Flash Unit

[Halo Photography]

About 2 years ago we bought an Interfit S1 AC & Battery-Powered HSS TTL Flash. It worked great for a year and we used it for HSS on weddings and was a great little backlight in our studio without power leads getting in the way. About a year ago it packed in and surprise, surprise just out of warranty. But then we learnt Interfit have no repair centre in the UK and could only suggest a repair guy who can't get parts. He has had it for nearly a year and can't repair it.
So my question is... Does anyone recommend a like for like replacement that isn't a dead duck if it needs a repair?

As your intercut was 500w I’d recommend either the Godox AD400 or AD600
Buy from Lencarta or Essential for after sales support, but I believe Lencarta have the only Godox repair centre.
