Meet the remote battery disconnect that makes sure
a RV's batteries are alive, well and ready for the road.
Battery Disconnect
is an easy-to-install system that will
allow RV owners to disconnect coach and chassis
batteries with just the touch of a switch. With
Disconnect
, the owner can be sure the batteries are
disconnected when his RV is not in use or being stored
off-season. It is conveniently located inside the RV, and
it's all remote.
The heart of the
Battery Disconnect
Intellitec invention. A latching relay, capable of carrying
heavy coach currents, draws power only when switched
on or off; yet, it requires no power to stay open or closed.
This sturdy relay is sealed against the environment and is
designed for the toughest use.
Unwanted battery drain during storage, or when the RV is
not in use, is not the only customer benefit of
Disconnect
. Batteries are protected from overcharging
when the RV is plugged in for an extended time. Battery
Disconnect also prevents shorts or fire hazard while
working on the 12 Volt electrical system.
Easy Installation
Installation detail is straightforward, easy-to-follow, and
is simple enough that your customers can install it
themselves.
