These look good from scanning through this thread and beats the post it note and pen plus spreadsheet I've used to keep track of things. Have 2 BM2's for the price of one ctek battery sense monitor, bonus!

Is it right Tim that you need one for each battery cranking and aux if using Traxide?

Any tips on where to place the monitor under the bonnet?

Hi,
One for each battery, as close to the terminals as practical.
Cheers

Hi duke and one is sufficient and just monitor the cranking battery.

But if something does not seem right, having one on each battery can both help to solve problems and it can also demonstrate in real time, how each battery is being charged.

This is very hand when on a long holiday, where batteries tend to get used far more than the weekend away type trip, when charging with solar.

As Austastar posted, mount them as close to the battery terminals as you can get them.

Thanks Tim sure it will come in handy.
