Be aware of LVC devices current consumption!

I thought I had finaly set up my rig as far as 12v goes and have been blaming the battery brand for early failing until I looked further!

The Low Voltage Cut out device I chose was supposed to be protecting my aux battery by cutting off any load when battery voltage dropped below the preset determined battey voltage..

YES of course you may say...that is what they are designed to do

BUT the device continues to draw current for itself after "protecting" the AUX battery from over draw.....no sleep mode...so after cutting off the accessories to "protect' the AUX battery in continues to suck it out to feed itself (I wrongly assumed very little draw)

AND I decided to test its draw......wait for it 0.14ah thus equalling 23.52a in a week....that is a hell of a lot of power out of a battery if its sits still for a week.....worse still as this vehicle of ours can sit for nearly 2 weeks = 47ah

Doesnt do a lot for protecting the battery!!!...in fact it stuffed it over successive periods

Phone the manufacturer and innocently asked what their device current draw was...of course the answer was we dont know! (In fact I am convinced they do that was why they said they didnt know..sceptical I know)

have now purchased another brand drawing <10 ma whilst monitoring and with a sleep mode ........and about to put a new battery in

My fault ....I guess I didnt look for the current draw on the first purchase and assumed being a reputable local brand that it was going to be well designed and tested

So the moral is be aware if you are not and if you have one of these devices might be a good idea to see what they are consuming.....never going to be a problem on a vehicle with regular use but a week or more parked up is a different matter

cheers
