I wouldn't say holy, more like cheapskate emergency grail, since it's a whole amp hour less than the original, and requires a lot of elbow grease to replace. Yes, I took the board off the original battery, it was soldered so came out clean. The replacement was similarly attached to its own board, but I ended up physically breaking it off by repeatedly folding the tabs, which I guess made them a bit shorter. If you are better than me with a soldering iron, or maybe use a heat gun you should be able to de-solder those as well, and that will give you a better surface to work with. They of co

They are just bare cells without the BMS PCB and connector to the Pro1. you would need to transfer them from your original board to make them fit. I am very sure that the cell´s sizes are identical to the pro1 and the pro1x, so those cells could be used on either of them as long as you transfer the respective board from your old battery. keep in mind that this is not really a rookie-job and you can easily mess up things, nshans way looks not very durable. But sure, for a Proof of concept it might be just fine.
