Most of the pack seems pretty good, but not sure about the battery capacity.
I've attached photos of the Ryobi-compatible battery pack I received around the beginning of June 2019, since it looks a little different from the product photo. It arrived with an open-circuit voltage of 18.88 volts, which seemed nominal, charged OK in a Ryobi charger, and fits and runs my drills OK. I was a little surprised to see it shipped from the Vanon store and is labeled on the bottom as a Vanon battery pack, but I suppose most if not all battery packs shipped from Plainfield Illinois share that heritage. I removed the four T10 screws holding the case together and examined the electronics inside the pack. The PCB had both a LM339 for the LED charge indication, and a Cellwise CW1053 battery protection circuit. I couldn't match the Lithium-ion batteries to those in an online database from what I could see, and the 18650HR15 marking made me wonder if they are actually 1.5 Ah cells instead of the advertised 2Ah. But, at least the batteries had a date code of 2019.03.09, which doesn't sound too bad for a battery pack received in June, 2019, and I guess I could live with a 1.5 Ah pack for their price.
