Not yet. Just finished testing the first 300. 32pcs ready to go in a badboy buggy this week. Should then feel comfortable selling some. They test over 70ah. Above 60ah specs. Should be no surprise as they are unused.🙂 4pcs make a 60ah 12v battery. 8pcs 120ah 12v battery. ---

I feel your pain. Last year I bought 48 new GBS 100 A/H LiFePO4 cells. I needed 32 for an EV Bandolero race car project. I ended up buying an extra 16 because the price was right. Going through them took a while.
