47 out of 56 turned out to be great! One pack had suffered water damage and had to be disposed of.  I’ll be using these across various projects, shortly on the Roomba, and they’ll be incredibly useful.   I’ll definitely be keeping an eye out for more, the packs the grey cells came from especially.  A good few hundred quids worth easy as they’re almost all over 2.5Ah and essentially cost what you all pledged last month so thanks for giving me the power to continue!  

Yeah, the puns aren’t going to get any better and I apologise for nothing! 🤣
