Here are the cell specifics of the 4 good LG cells i pulled from the Ryobi battery pack.
https://lygte-info.dk/review/batteries20...%20UK.html
Note his conclusion at the end.
This cell is rated at 22 amps max, and only has 1500mah capacity.
I know samsung has a 30 amp 18650 cell.with 3000mah capacity, and 21700 cells are.now being out into some.powertool battery packs.
Some.of these are rated at 4500mah amd 50 amps max. One coukd possibly get/make a 4.5ah 18v battery out of just 5 cell,.or a.9ah battery out of 10.
The 2 4.0 ridgid 18v battery packs.for 79$ is likely using 10 2000 mah cells, but which cells?
The 4 good LG cells i pulledd from the ryobi pack test very similarly now, after lots of abuse then sitting on the shelf for years.
Its important to have relatively closely matched grade A cells, which js why i dont trust the generic half price makita baTtery packs.
I was.going through cheap 6 and 9 cell laptolp battery packs, and when theyd fail and id test the ok cells.individually, their capacity was all over the place, and way low, 450 to.600 mah.
I quit bothering with trying to repurpose them.
The 2 ridgid 18v for.80 $ deal has me suspicious.
Perhaps they are about to offer a new line of marginally larger 18v batteries with 50 amp rated 21700 cells.with 4500mah.
Perhaps these 80$ deal.batteries are known to have the occasional bad cell And high return rate.
Anyway i want the jobsite blower, and more batteries, but dont really need them,.presently.
