I have a stack of Ozito hardware at home which I use a stack
Recently Ive picked up a Ryobi scarifier and grabbed several aftermarket Ryobi batteries and they are cheap, easy to get and work really well
I cant seem to find aftermarket Ozito suitable batteries, and no-one makes Ryobi battery to Ozito tool adapters (probably due to the shape of the Ryobi battery)
The pricing for genuine Ozito batteries is now pretty high, not that there are ever any in stock at my 2 local stores
Any options would be super!
There was someone on Gumtree selling various adapters they had printed, including Ryobi to Ozito a few months ago.
Might be worth a look and a Google.
Also, try sites such as AliExpress for adapters.
