When failure is not an option
These are the best battery cut off switches that you can get. Expensive, but you get what you pay for. They're easy switches for dumb people to operate. Just teach them first. You can mount it wherever you want, and control it from wherever you want. I use these on ambulances and custom projects.

Excellent unit. No current draw when left on!
Used as switch to isolate or enable lithium house batteries in a RoadTrek RV. So much better than the original battery switch mechanism (which drew considerable parasitic power when on).

Works great on a 48v battery and the coil operated from a 12v battery.
I use this latching relay to connect/disconnect my 48v lithium battery to my boat’s electric propulsion system. It is driven by the battery management system from the 48v battery. The BMS is powered by the boat’s 12v house bank, so the coil of the switch needs to be the 12v version. The remote button still operates and is not impacted by the BMS connection.

Top Empfehlung
Dann mal eine Rezension auf deutsch. Kann diese Batterieschalter nur empfehlen. Sie funktionieren einwandfrei und sparen lange Kabelwege und dadurch Leistungsverluste, da grosser Querschnitt nur bis zum Relais verlegt werden muss, dass nahe der Batterie montiert wird. Der Rest läuft über eine einfache Steuerleitung bis zum Schalter. Der Preis bei diesem Anbieter ist top und liegt weit unter dem üblichen Marktpreis. Er schwankt allerdings stark. Habe zwei für 149,-€/Stck. erstanden.

Very good quality
The remote battery disconnect is very well made. It takes a bit of thinking to understand how it works, but nothing that complicated . I found a YouTube video that I found helpful
