VERY interesting. Anyone found some more info?

 

Will be interested to know if this can save home electricity costs also, more so if you can use solar to charge daytime.

Nope. If you want to save, get solar panels. Just do it.  :D

The moment you touch batteries, it is open season for costs, even thought they say ti is 'free' to the customer.

25deg C is the average comfy temp for batts.

I am led to believe:

The colder they are, the better they operate, the shorter their life. I am talking colder is in sub zero.

The hotter they are, the harder they have to work, the shorter the life. Like in the dessert.

So the average inside temps in SA, is not that big a problem, unless you have them in a shed in the sun.

I could just look this up, but someone asked on another thread if we do temperature monitoring. Well... I have two temp probes but I haven't gotten round to connecting them, because I cannot remember on which side of the battery they go. Can someone refresh my memory? :-)

Are you referring to the Victron sensors for the BMs?

 

From the BMV702 manual:
Battery temperature monitoring
Wiring diagram: see the quick installation guide. Fig 4
The cable with integrated temperature sensor has to be purchased separately (part no: ASS000100000). This temperature sensor is not interchangeable with other Victron temperature sensors, as provided with Multis or battery chargers. The temperature sensor must be connected to the positive pole of the battery bank (one of the two wires of the sensor doubles as the power supply wire).

No, I actually have two sensors that came with other Victron equipment. I have one that came with the Multiplus, and another that came with the MPPT charge controller. So I decided to stop being lazy and just looked in the manual. It says it has to go on the negative pole. So perhaps I'll go rig that up when I get home this afternoon.
