Well packaged for shipping and arrived in good shape despite boxes being obviously poked by a set of forks but seeing these were in foam, the battery was not damaged. Arrived at 43% SOC - good. Arrived well balanced, cells within 0.008v - very good. I charged up to 100% using a bench top power supply and was able to hold top cell at 3.650v until they balanced nicely. Not sure if this step was necessary but I did it and it worked great. Bluetooth app works great! I wasn’t even expecting to get Bluetooth for this price so I’m super happy with that. These seem pretty high quality to me, although I am new to lifepo4. I’ll be putting them into service very soon, time will tell but I think these were a great deal so far.
