Recommend ryobi one plus compatible batteries ?

Got a few ryobi cordless bits of kit, my other compatible one plus batteries have all died, after quite some use, the seller no longer exists. And one battery I bought a while ago, really wasn’t that good.

So looking to get a couple of good 5ah, or 6ah that really are what they claim to be.

There’s a lot around that are 8ah for twenty quid, which is clearly garbage.

Anyone recommend any ? Obviously I could buy the OEM genuine articles, but this isn’t for my main diy kit and not used as much, so I’d like to keep costs down.

Adaptor to use whatever your main system batteries are on the ryobi?

@Shackleton thanks – what a brilliant idea. Off to Google makita lxt to ryobi adapter.

(And why the hell did I not think of it.)
