USB sockets are becoming more commonly installed on motor fairings to assist officers with charging cell phones, helmet headsets, etc. However, many of the available sockets when connected to the fairing power socket confuse the BMW 2.5Ah battery charger by creating a small parasitic load. FMS has sourced a quick-charge 3.0 technology USB socket with an On-Off switch, enabling the officer to turn-off the socket when not in use, therefore not creating issues during battery charging (particularly off-season storage when connected to the fairing power socket outlet). Additionally, the USB has a digital voltmeter, enabling the rider to see the state-of-charge of the battery that the voltmeter is connected to (based on the connection type selected). The voltmeter is also visible through the waterproof cover. When connected to the auxiliary battery power source, the voltmeter provides an excellent indication of your auxiliary battery state-of-charge as well as when the motorcycle is charging the aux. battery.
