Your packs are from Volt, which never had a battery recall AFAIK. Even though Volt packs were also made by LG, it's a completely different module design, likely made on different production line, where drunk or blind QC team wasn't allowed in
Many DIY batteries were made with Volt packs, quite successfully, so your aren't alone in the happy camp. Just treat it well and it'll serve you for many years. EV batteries are supposed to get a second life in solar storage, so you are doing the ring thing.
