BLSOLAR2  2.5W Solar Battery Charger and Maintainer

2.5 Watt Solar Battery Charger and Maintainer

The BLSOLAR2 is a 2.5-watt solar battery charger and maintainer for maintaining 12-volt lead-acid batteries where A/C power is not readily available. It provides up to 180mA of trickle charging current directly from the sun to counteract parasitic drains of most vehicles, such as cars, boats, trucks, motorcycles, ATVs, RVs, lawn mowers, and more. Its ultra-low profile design makes it simple and easy to install, and completely weatherproof for outdoor use.

    More than one way to charge.

    Charge inside the vehicle or outside.

    Keeping your batteries fully charged and maintained is easy. Just connect and expose the solar panel to the sun. Use the existing 12-volt auxiliary port for in-vehicle charging, or connect directly to your car battery. If your car disables the 12-volt auxiliary port when the ignition is off, then you may need to use the vehicles OBDII connector.View X-Connect OBDII Connector

    Efficient design.

    Low-profile design with homogenous solar cell structure.

    The thin-film amorphous solar technology makes a homogeneous solar cell configuration for maximum solar output. Its rugged fabricated TCO-coated glass substrate optimizes the optical absorption to allow for a wide-spectrum of solar radiation. And its low-profile design improves installation and performance in high-heat applications.

    No worries.

    Powerful but safe.

    Battery Life maintains your boat or automotive battery with enough power to fully charge your battery but not too much to damage your battery or any of the on-board electronics. In order to prevent this the BLSOLAR2 panel comes with integrated protection to prevent any back current from happening.
