Hey guys, chippy from Australia here.

I have this cursed 54v grinder that when you put a 54v battery in it, it shorts out or something along those lines and then those batteries struggle to charge and only really work in 18v tools. By the time I'd figured out what was happening I'd put most of them through the grinder.

Is there a fix for the batteries to get them charging again and working in 54v tools?

I wouldn't care if it was one or two batteries but it's 4/5 54v batteries I own.

Has anyone else had a similar issue?
