Since I purchased these batteries many months ago the price has come down from 299AUD to 199AUD so math will be a little off.


High res Photos of the Genunie battery, notice the fuse and temp sensor!

Wow, that's a horrible solder job

I would imagine that the weight difference is from a few different things.
1) different material for the case
2) less plastic used in the case
3) less solder on the pcb (note the picture above)
4) obviously less pcb material (note the picture above)
5) less capacity cells
6) and i would hazard a guess that the metal used (wire and strips) are smaller gauge than the authentic pack is too

All of the above

You're probably right that the ryobi will seem much more powerful on the blower. Those nickel strips are much less substantial than what they use on the ryobi packs. Other than that, it doesn't look that bad of a pack?

You should test it by draining it at high amps. That's what you're paying for when you buy that 9ah pack. Those high drain devices like your blower likes those high drain. How about testing it on the blower to see the runtime for those!

On the other hand, I upgraded a couple of my packs into double packs. Took a 3d print from the internet and doubled the height and soldered another row of batteries to the existing holder. Good way to extend your current packs!

can you see whos cells are in these?
all the real ryobi packs i have seen had samsung or lg.
had 1 knockoff that had generic 2200mah laptop grade cells.
they must have thought that in 3p they could get away with it.
they were beat.
400mohm beat!

And that changes a lot because with AU$300 the choice was obvious and not in favor of genuine battery (at least for me) but at AU$200 MAYBE I'd take it if i used it in a high-current device. But even at AU$150 it's still overpriced, imho...

PS i like those beautiful busbars in genuine pack!
