Ampper Battery Disconnect Switch, 12-48 V Battery Power Cut Master Switch Disconnect Isolator for Car, Vehicle, RV and Boat (On/Off)

Easy to install and works great, you need a lug with a size 10mm ring Recommend

Just what I needed

This was rated at 275 amps for continuous current but it melted after running 180 amps through it for 20mins

Seems to be an OK unit. Annoyingly though the battery icon is upside down.

Use in my camper van works well

The post are definitely not 10mm. Seems like not so much a problem until you try to fit it into a camper where every battery connection is 10 mm and most a routed through the van. Every standard battery connection is 10mm and each of the 5 cables I have attached have had to be painstakingly drilled out in situ to get them to fit. It’s not badly sized 10mm connectors, they range in age from 29 years old to a set of connector from Amazon and a new earth lead from Halford yesterday. I don’t normally write long reviews but when a misdescribed advert leads to a job taking three hours instead of five minutes I simply have to. If you have existing 10mm connectors I would suggest buying a switch from someone that can measure! Update. It stopped working (thankfully stuck “on”) after about three months. Just getting around to sorting as the leisure battery is now dead and remembered to update the review.

You can spend hours or lots of money trying to find every power vampire in your RV. I spent two seasons with my battery always being completely dead when I came back to my RV despite all my attempts to get them all shut off. I put one on my snowplow truck so that I can preserve my battery during the many months it is not used. I bought 10 feet of 4 gauge cable, and used it to run the negatives from my engine compartment through the firewall into my cab to the switch, then a second cable back, and done !

I got this to stop a circuit setup for a small scale solar operation. It'd very study and works a treat. Excellent safety festire to have in any similar setup. Item feels like nice quality and came with the backboard which I've seem other reviews for similar products to say that one wasn't included. So your good with this one.

Nice quality switch. Works as intended.

Der Schalter an sich ist gut verarbeitet. Nach etwas mehr als einem Jahr hat der Schalter von jetzt auf gleich Übergangsprobleme wodurch die Solaranlage sich abgeschaltet hat.

キャンピングカーのサブバッテリ切り替えに使用。 操作しやすい＆コスパ最高

Easy install, works perfect and is a nice feeling knowing you’re not coming back to a dead battery due to a draw or something accidentally left on. I recommend. Thanks.

Good quality.
