@gwatuk "Just over a year ago I posted with the same title as this one (the balancing period then was 8 minutes). Our car (SE SR) is now 16 months old and has almost always been charged with a granny charger. The balancing period has always been less than 10 minutes."...

If the balancing mine (excite) does is what is OES then its pretty mediocre as mine stops at over 100mV delta. Driving to 98% brings it to <20mV. Given up investigating. I just jump in and drive it. Haven't used the OBD port in ages. Geez, I think ive brought this up before , here I am repeating...

Yep, I inflated them all to 260kpa and notifications stopped.

Yep, I think you’re right. I was attributing the “left rear or right front low” (whatever) to a delta triggering the warning but after bringing them all up to ~260 kPa and resetting, the 4kPa delta doesn’t issue a warning any longer. I think they were alerting as they were too low. Nicer ride...

Just read 20 pages on subject. Definitely wont get that time back! Consensus was to pump to 260Kpa / 2.6bar minimum All round. pref more. That a 4 Kpa (<2%) delta should send a alert to your phone is somewhat ridiculous IMO. That why i wondered if there was a way to increase the delta. I dont...

Anybody getting bulk notifications on tire pressure delta of only 4kpa? Any way to adjust to say 10kpa. Downunder models. (Excite)

American fashion statement. Ban finesse.

Circus music. Thats appropriate.

This is not what happens with my MG4 SE SR 25k km. 2023 demo My observations: 100% is triggered by cell voltage of highest cell hitting 3.65V HighestV/Lowest V cell Delta at this point is 265mV. On hitting 100%, power in drops to ~300W instantly per wasmac above "Balancing" takes up to...

What are the visual readings for "properly balanced". In terms of, delta HV/LV at 100% SOC with no loads and how long to achieve at rest on charger? I realize you have a trophy and NMC, so in my case for LiFe and SR/SE. Anyone? (Max/min cell voltage through OBD2 and car scanner)

Over a year in, 25k km , great car, a few software WTF's, don't really care as it drives so well & as T1 put it its the poverty pack. Given up on under engineered balancing. LIFEPO4 are pretty tolerant for current negatives. Lost interest in updating myself. If it aint really broke, dont fix...

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...
