New additions to the Ring range of accessories this summer are 2 new green energy solar powered 12-volt battery trickle chargers. The popular RSP150 is now joined by the RSP240 and RSP480. These are perfect for leisure vehicles and boats that go unused for long periods of time.

Lately factors have had quite a few requests for these chargers from BMW drivers, who are experiencing battery drain even when the ignition is off. Solar chargers don’t need sunshine to operate, just daylight is sufficient.
