L405 2018 low battery

Just wondering has any one else had this issue as mine occasionally puts low battery start engine and boot door won't open but car always started but then on sunday it wouldn't start had to get land rover assist out any ideas want would be wrong

I’m getting low battery messages at the moment (MY17) when I don’t drive it for a few days. Always starts though. I’m investigating whether the BlackVue DashCam, which is controlled by their ‘magic box’, which should switch it off the DashCam when the battery voltage drops below either 12.5V or 12V (you can select), is the cause. It consumes around 350mA when in park mode. MY23 D350 HSE

I don't have dash cam and still got the problem mine is in dealers at the moment will let you know what they say

Had the same problem with mine and the dealer said they'd fixed it and replaced the battery. All was well until about two weeks ago and I had the warning again on one occasion.

I rang the suppliers of my Blackvue 750 2CH dashcams and they advised me to alter the settings on the magic box fitted behind the lower glove box. I did, and had no warnings since  All LR cars from 1984

Chalky - out of interest what did you set the magic box settings to? MY23 D350 HSE

Here you are, here is a link to the dachcam settings. I think mine is 2-on,3-off,4-on and 5 off. All LR cars from 1984

Thanks. Changed mine to 12.5V but the BlackVue switches off when the engine stops which defeats the object of having the magic box. The change did seem to stop the low battery warning.

Have updated the BlackVue firmware and set the magic box back to 12V. Waiting to see the outcome. MY23 D350 HSE
