The TJM DC/Solar Battery Charger allows you to charge your 12V auxiliary deep cycle battery on the go. Able to simultaneously charge from both solar and 9-32V alternator inputs – meaning it can function as an MPPT solar controller – it’s also shock, vibration and dust proof (and water resistant), which makes it perfect for either in-vehicle or under-bonnet installation. Class-leading features include safe operation at high temperatures, intuitive 3-stage charging and full compatibility with GEL, AGM, WET and calcium batteries.
