Battery Monitoring

Is there a problem you need to diagnose?

I cannot be sure what sort of advice you are looking for. Product quality, capability, reliability, ease of use etc.
Both of these monitor the battery and communicate to a phone app by Bluetooth. They each display battery voltage and the BM-PRO also displays instantaneous current.
They each have a low voltage alarm.
They both display with fancy dials and bargraphs but are still no more than a voltmeter although the sales pitch may lead one to believe more!
They are not suitable for installation within the engine bay and the BM-PRO is limited to a maximum of 80 Amperes.
As an alternative to conventional volt/ammeters they have the advantage of not requiring mounting of gauges on the dashboard.

Hi Steve,

Can't comment on the CETEk device, but I have a BM-PRO on the house batteries in my caravan.
It may be a bit of a gimmick, but i do find it useful to see how much power we consume over night depending on tv usage etc, when we are free camping.
It also is good to know how much charge the solar is putting in.
I know you can get other gauges to do this, but this suits my needs.
Having all the info in one simple device.
PS I have no idea how accurate it is.

Tooley,

Ive got a Ptojecta Dual battery monitor in my Patrol and its fantastic! Early version was a bit dodgy but replaced under warranty (twice) and Third one is a total internal redesign and works a treat! Small, easy to read and very low drain so it's left on 24x7 even though the vehicle only gets driven about once a week does not flatten the batteries.

Ive also got an RV Electronics Dual tank and battery monitor in the van and whilst early days looks good also.

I thought about a dual battery monitor in the van but no point as they are always connected in parrallel.

Thanks all
