That why I called it an arbitrary benchmarker and is not representative of average voltage either; for my setup NV is at <20%SOC resting. Given that I, V and load are dynamic, SOH can only be definitive with repeat capacity testing. And it can be "massaged" too as people have reported. I am...

Where do you go in carscanner for module max/min Voltage? In data recording it only gives max/min for pack Dashboard?

The whole module voltage (multiple cells in series) or cell voltages per module? VDS is not available from engineering screen, right, only via VNCI? And buying access time.

Wow, a lot of effort there. Bravo! Always suspected 3.2V nominal was a generic figure for average voltage. A bit of "fudging" or fuzzy logic going on to keep the battery out of trouble zone and user relatively happy with performance. Then there is what Terry said about nominal voltage being...

That is 123mV moment of finish charging or charging and balancing? That is, exactly when it hits100% or a time period after when balancing is complete? Your balancing method seems to be working well. I googled your model an it appears LiFe blade batteries max cutoff is 3.8V as opposed 3.65V...

Did you do that in real time with carscanner accelerating hard until you got a delta of 90mV @50% soc and then flooring it, or is that from manufacturer? Don't laugh, I have done similar!

What is the current update for the excite for Au/NZ? Mine is 1100 R05 Has anyone installed essence SW on an excite? I am aware it has been done Trophy to SE. And is there a copy available for R05 in case I want to go back? Just curious.

It is of concern that MG has advertised a lengthy warranty with fish hooks and which it seems to resist honoring, generally across the board, from software updates to faulty hardware. It would be curious to know what budget they have allowed for warranty claims? Every manufacturer has their...

Right! Good to know as I have no experience with NMC. I would not be happy with a cutoff of 3.75V as factory specs for my other LiFePO4 is 3.65V max. BYD builds their own batteries. Perhaps their specs are higher?

The Atto3 is LiFePO4 right? If so, that is a high cell, high voltage cutoff for LiFe. 3.75V suggests its for NMC. "OBC in my car not lowering charging current at 99% it keep charging untill any of cells get to 3,75 volt and then charging stops and battery capacity resets to 100%" Similar to...

Still don't see that you can use that "nominal V" at the top end and get a meaningful result tho.

896Wh for 280Ah is a contrivance just like 3.2V is the same for “average voltage”. If you extracted 896Wh out of a 280Ah battery via wattmeter then recharged it to same "soc", then discharged it at same rate with CC, and the those figures panned out then who am I to argue with 3.2V being...

Actually I have always taken SOH with a grain of salt. My CALB cells capacity tested at 231 to 234Ah, so I set them at 230 so they should have read 100+%. Nope, 95%. And they are still at 95% three years later! Balmar BMS. Never took a shine to Balmar stuff , except for their voltage regulators...

Can't agree there Terry. AFAIK, nominal voltage is arbitary figure @~20%SOC for LFP. And, as above, efficiency is bollocks. Besides, why are Carscammer and VDS so different?

Sorry for inquisition, but a lot to absorb here: VDS software via your google drive link? So this enables you to access the master bms via canbus, (or your account login does.) To parse the data into a different format would require tweaking the VDS software, or is this built into VDS? AFExx...
