New LiFePO4 installation charge parameters

[Muskoka]

Just finished Absorb, went to Float, no issue. Soc at 100%, will keep any eye on it for any abnormalities.

Bob - it is night here now - and the SOC seems to be working okay and is tracking the same as the Hawkes Bay.
Maybe it just needed a couple days to get in sync for some reason - at least no zero percent.
I went back and looked at SOC data history and it seemed to leave zero % and go back to 90 something last night when I did the VMM a couple times when I was checking Flooded and then VMM again to go back to Lithium.

Soc reading looks to be fine at my end, nothing odd to report.

Yea the wbjr does a nice accurate job . Better than my pack BMS . I have two they are usually only a 1% or2% off from each other I usually use them to check my Kong BMS to ensure they are not falling off . They usually do.
Particularly the older generations.

That should have been Jkong or Jkbms auto correct is bother some at times

Thank you Mahendra !

74 degrees in Phoenix AZ  today.   

[Muskoka]

Grey and -12c (10.4f) with the wind chill here.

Suppose we're lucky, should be 2 ft of snow out there still this time of year.

Sure looks cold there, Muskoka !   Brrrr...   That is why I am working down here in AZ for the moment.

So, new information on this latest Classic beta code.  MNGP  3798  and Classic 3800...

The Classic has been CRASHING...  So far it appears to be only the Classic 200 and when the system is using FOLLOW-ME.

So far, ENDING AMPS has been above zero amps and also possibly ONLY at night.

Please let me know if you guys are using Follow-Me.   My  single Classic 200 has been working great here UNTIL I plugged the F-Me cable from its SLAVE to its MASTER jack and F-Me was turned ON in TWEAKS.

So far TWO beta testers, including Wizbandit in Florida have had 4  Classics in a crashed state when they woke up.  More than one time for my friend here in Phoenix.  His Classic 150 has  NOT crashed yet.  Not sure why that would make ANY difference at all since the code is 99.9% the same and nothing different in code areas that should affect this.  Just voltage and current limits.

So be aware.  This is why we have betas.  Thank you for the help here !

BTW, there was a big solar flare this week.  Maybe that was it ?  LoL

Sorry, I have not updated my classics since the last rev 2193.

Sorry, I have not updated my classics since the last rev 2193.

Oh, OK.  Good.   Don't update it with this code.

Are you running multiple (2+)  Classics using Follow me ?
That appears to be the problem here at least.  So far as I can tell.

Thanks,

Yes Bob that would be correct classic 150 and classic 200 ,
Both with their own wbjr (a bit cropped on one shunt but working)and follow me.

Thank you Mahendra.  Are you using Ending Amps ?

I thought that it was only Follow-Me that was causing the problem but my 200 crashed with F-Me turned OFF but the cable still plugged into itself.

Bob , my single Classic 150 has been running fine with this code.
I don't think I want to try turning on Follow Me to test it out !

Larry, I think this MAY only be Classic 200s actually.  I have not seen or heard of a 150 with the issue.

Thank you for testing! My 200 in AZ has ran fine for a couple weeks until I set it up with its F-Me cable plugged into itself and also raised the Ending Amps from zero.

Weird !  It can take just a byte or two increase or decrease in code size to cause a crash like this.

I will check but I am not sure if the 200 and 150 have different code sizes. 

Could also be an interrupt walking through the code in time and in just the right spot, bam !  It goes into a fault.  I have been very fortunate in past years for something random-ish like this to happen.  I have seen it many times but not in any beta I have sent out that I remember.

We will find out what is rotten in Denmark !

Yes boB . Using end amps definitely.
