The external rechargeable Li-Ion Battery is designed to provide an additional 10 hours working time during prolonged usage of all Flowmaster models.
It is designed to simply clip onto the carry handle of the Flowmaster and connect to the charging port of the device. When the meter is switched on the power source will default to the external battery. Once the external battery is depleted the unit will automatically switch over to the internal battery, which will provide a further 10 hours working time.
A distinct advantage of this system is that the external battery can be charged during the period that the meter is running off the internal source.
