Hi Mike,
Given it some time, and the little Equaliser in the shed has made some difference, there is less voltage rise on some of the cells, thing is I have one cell that has been consistently lower than all others at the top end of the bulk charge, its been this way for years and have at times given it a charge up with a 40A charger, the Equaliser should help out with that cell, just don't know how much, time will tell.
This one cell would be a real problem for someone expecting to use 80% of the battery capacity every night, but if using 30% or something it's not a problem yet, I could later swap it out for another cell that I have spare, but like to see how far this will go.
I think the Cycles are calculated on accumulation of of each percentage of capacity used each day until its 100% then that's 1 cycle? I could be wrong too.
Installed the PC SW V2.1.9 the other night Had to wake it up using the button on the dongle and tried a few settings in the Active Equilibrium tab, some settings were a little different to the APP, also it was set For Li-ion, set it to Lifepo4, it was asleep this morning and it woke up after waiting a few minuets while the battery voltage rises, it had set itself back to Li-ion again, the voltage settings were still as I set them.
Found a PC Master Software_V1.0_manual, it sort of explains some things.
Oh the old phone app has no way to switch the Equaliser on/off, I think the later version has.
The 150A Daly BMS in the shed has been a rock solid performer even though I have given it a thrashing, the SOC is pretty close too.
On the phone app I set the voltage trip a little lower than the BMS and it will give an alarm cell over voltage level 1 and later it will spit out level 2.
The BMS will give an alarm "cell over voltage" when the charge mos trips off on the phone APP, I have never had over current so far but have it set for 200A, I think the surge current and time can be set in the pc software, not sure if that really works, they did call it sparkle current on a spec sheet, The first thought when I read sparkle current was the end of the welder, not something that should be attributed to a BMS.
So far I haven't used a pre-charge on the inverter charger after the BMS, just slammed the breaker on and give it hell, it must be close to tripping the over current, only done that a couple of times, will add a pre-charge switch one day
There is "Current wave" settings will have a look at that soon, might help with more accurate readings.
Might have seen this already, or someone else might want it, https://www.microcharge.de/anleitungen/PC_Master_Software_V1.0_manual.pdf
