I've bought two of their 100ah 12V LiFePo4 batteries recently. One with bluetooth and one without. The batteries were shipped quickly from Germany to Ireland. Packaged well in two layers of cardboard. Both arrived partially charged. I'm currently charging them and will check the capacity and report back. I've taken one star off for two reasons. Firstly because the app needs improvement. It reports cell voltages and temperature (can be useful) but reports 100% SOC when the voltage is just over 13V - far from being fully charged. Also, everytime I plug in my phone's powercord the app closes or refuses to connect to the battery! Secondly, and more importantly, because according to a review on their site a customer got no response from their support when they wanted a battery with a defective cell. That's somewhat worrying.
