Hi,
I am thinking about, how to replace my old AGM batteries and was reading data sheets.
I spotted this:
150Ah: 20Kg; 160Ah: 33Kg
Why is the 160Ah Lithium batt. so heavy in comparison to the 150Ah version?
Is this a typo?
Regards,
Markus

Looks like no one wants to answer this, so it must just be as
Mark Guessed - It must be the M8 vs M10 terminals... :-) :):):):):):)
:o) Thanks Paul, but I don't think so. I hope someday, someone will answer this, as I really wan't to know that.
Maybe @Johannes Boonstra (Victron Energy Staff) knows... ;o)
...but chances are better when the question remains unanswered. ;o)
Now being a bit more serious... I don't think the significant weight delta is a typo.
If you calculate the volume, the 160Ah is more than double the volume of the 150Ah.
11,564cm^3 vs 25,201cm^3.
So you would expect a significan't weight increase - possibly even more than stated.
The weight per Ah of the 160Ah is also very similar to the 200Ah.
So I think that between the 150Ah & the 160Ah something significant/notable must change with the internal construction/configuration.
But what is different I have no clue... maybe a different cell layout with more links...
Weight normally doesn't lie so I would 'expect' the 160Ah to be the better/more robust battery but in this case who knows.
Hello, Yes, these numbers are correct, this is because the energy density in the LFP cel's is improved over time. The latest added models (100Ah and the 150Ah) are therefore lighter per kWh then others (as the 90Ah and 160Ah). (and yes, these last mentioned models will be discontinued in the future.)
