Battery Brain

Anyone used one of these before?

The concept seems quite cool.

Might get one installed.

Can see the benefit but most I assume connect their cars up to battery conditioners when car is in garage.

I think you would be better off with a disconnect switch, either auto or manual and a wire to the alarm

My garage doesn't have any power and it is remote from my house.

But if you have a kill switch does it not invalidate your insurance as your alarm is not working.

I have a very similar item on my car to protect the £400 worth of lithium batteries I run instead of the stock item... cheap at around £20 and worked great (I NEVER run a trickle charger on my car, if the battery drains you have an issue you need to sort IMO and if i leave for more than a month I charge the battery regardless or run the car).

I was sold until I was driving along at 5pm on the motorway in a contraflow and the car litteraly just cut out suddenly with no power whatsoever... que miles of tailbacks in a single lane behind a dead sportscar... great fun.

What had happened is that I had some work done fixing a slight oil leak behind the alternator and somehow the wire had shorted out and blown the fuse between it and the battery (too much insulation around the wires I later found out)... this of cause meant the battery wasn't charging... all was great until it dropped below 11v and the device did its job and shut off the batteries leaving me stranded.... yes there was an override, but it didn't work for some reason (had when tested tho).

What I am going to do in the future is run the cut off on one of the batteries so I still have one battery connected... until then I have bypassed the device

I see this would be a problem if you had a tracker fitted and didn't charge the battery. Once it cut the battery you would get a call saying your battery had been disconnected shall they send the rozzers or you would just deplete your tracker battery and have to pay out for a new one to be fitted.

I prefer just to run the car around the block every 3 weeks. I saw a slightly different product here: https://www.youtube.com/watch?v=IdZES5CQz9I but it looked good.
