JMP Skan Monitor 2 Lithium Battery monitoring with your smartphone: With the JMP Skan Monitor 2 and the new free Apple or Android app "JMP BatteryMonitor II", you can quickly and easily check the charge status of your battery. Only with a consistent, positive charge status of the battery is the full capacity and usability guaranteed. The positive charge status also prevents potential early damage or failure of the battery. Continuous recording captures the battery's charge status during rides and can be accessed later. The file with the data can be sent via email from the smartphone and displayed in Excel. This allows you to quickly identify where the charging voltage dropped or was too high. Additionally, a defective regulator can be quickly identified. Furthermore, the new app can also accurately check starting processes (starter, cable connections, etc.) and charging processes (alternator, cables, etc.). This saves long troubleshooting in case of problems. In case of low battery status or other issues, a notification can warn the rider depending on the settings in the app options.
