Battery For Ryobi One + Tub Vac (Kirkstall LS4)

I'm slowly sorting what little I had stashed with friends and I'm finding I often only put half of the item.
So, I have my tub vac with some of its tools, but it's 18v battery only and I didn't put the battery and charger with it...the small tools I can probably sort but they too are missing.
I now have a charger thank you...
Apparently the battery and charger is universal across the range but my old power tools were Dewalt( all also gone) so if someone wants rid of any Ryobi one+ tools, too I most certainly wouldn't say no.
These are worth travelling a little further for, so if you see this ad and can help, give me a shout
Thanks in anticipation...
