Simple, great split charger for a camper.
This split charger is so simple to fit, just crimp the eyes on the feed, supply and earth, bolt them onto the unit snd bob’s your uncle. You do need an ignition feed if your vehicle has a smart alternator and a connection to earth for the small black lead, if you are using calcium or AGM batteries. But all connected and working perfectly.

Great charger but for the price it should have WiFi/bluetooth
Excellent it of kit. Replaced a split charge relay and my batteries thank me for it. Leisure batteries hold a much better charge now but the main difference is the health and charge state of the starter battery. It's an absolute no brainer purchase. I wish the additional bypass was a little cheaper however; seems to be disproportionately priced Vs the charger imo and marked down for no connectivity - for the price, no WiFi/Bluetooth is ridiculous.

Geiles Teil! Tut genau dass was es soll. Hab es seit knapp einem Jahr in meinem T6 mit 200W Solarpanel verbaut. Läuft!
