They work great with both the app and with a K4 charger I have. Be cautious to set the correct battery type. I set it incorrectly and had the battair set to discharge after 5 days and it took the cells down to the incorrect voltage with ruined the lipo. In the pics below the lipo on the left had the BattAir plug while the one on the right does not.

Great! Everything fit.Delivery time was as advertised and the modules work as usual. The fact that the Bluetooth connection is not always interference-free seems to be due to the technology of the modules. I also know this from other modules from other suppliers.

Klasse! Alles hat gepasst .Lieferzeit war wie angekündigt und die Module funktionieren wie gewohnt. Das die Bluetooth Verbindung nicht immer störungsfrei ist, scheint an der Technologie der Module zu liegen. Das kenne ich auch von anderen Modulen anderer Lieferanten.
