Includes Japanese translation instructions. You can monitor the battery status from the smartphone app BM6 via Bluetooth. It records the state of charge (SOC %), voltage (V), and battery temperature (°C) at 2-minute intervals for 24 hours, for a maximum of 30 days, and also stores the starting voltage and starting time of engine starts (cranking). The stored data can be exported in Excel format. If you allow location information and run the app in the background, the location where you parked your car will be displayed on the map. Driving tracks are also recorded, and driving time and distance are reported. Shipped via Yu-Packet Post Mini.
