JMP Battery Monitor II

Battery monitoring with the smartphone
With the JMP Battery Monitor II and the new and free Apple or Android App "JMP BatteryMonitor II" you are able to quickly and easily control the state of charge of your battery. Only with a stable, positive state of charge of the battery, the full capacity and usability is guaranteed.
The positive state of charge also prevents possible early damage or failure of the battery.
Due to the continuous recording, the state of charge of the battery is detected during trips and can also be recalled later. The file containing the data can be sent by email from the smartphone and displayed in Excel. So you can quickly see where the charging voltage has fallen or was too high. A faulty controller can be quickly recognized.
In addition, the new app can also be used to carefully check boot procedures (starters, cable connections, etc.) and charging processes (alternator, cables, etc.). This saves long troubleshooting in case of problems. Low battery or other issues may alert the driver depending on the settings in the app options.
After simply attaching it to the battery using eyelets and downloading the new Android or Apple app, the current voltage value can be retrieved.
The transmitter is suitable for 6 V and 12 V batteries. 
The range is about 10 meters. 
The connection is via Bluetooth. (Only from Bluetooth 4.0, eg from iPhone 4s, iPad3 or iPod Touch 5)
