I have got the system humming along now so no great urgency, but each of these is showing a slightly different state of health, around 90%. So I would like to “exercise” them up to 100%.
To me they look like Pace BMS’ but Pace says they are not based on serial numbers.
The supplier (Micromall, Auckland, New Zealand) says to get them to report 100% soh I need to apply high voltage for a long period but that is tricky being off grid with only solar. I was hoping to tweak the BMS to allow charging to 100% SoH but for that I think I need to find a group like this that is knowledgeable about this BMS.
So, does anyone recognise these batteries? Or what more information do you need to help idenify them?
I don’t know. All documentation and software is generic. Is there a manufacturer in the background who white-labels for people like Micromall all over the world?
Currently using with a vendor supplied USB-serial cable and Windows software, and a hand made BMS CAN cable which works fine to determine SoC and send CCL (but not CVL) signals from battery to charger.
This works fine except that initially there was nothing between “send me amps, baby” and “sorry, I’m full”. I don’t know if the GX device is learning- probably too much to hope for- or whether the other tweaks I have done have reduced the incidence and impact of that.
You seem to be suggesting these are Pylontech batteries. Is that a reasonable assumption?
Thanks

Thanks again,
You suggested http://multisibcontrol.net/ who claim to be for “for monitoring and control of PIP/Axpert inverters and Pylontech batteries”.
I’m unfamiliar with PIP and Axpert but the link looks very interesting - do Victron inverters match “PIP/Axpert”?
The tool seems to read other batteries as well. No the victron does not work like the axpert.
The other tool that works with pace that is available is pbms tools. Which i was going to link in my previous reply and fogot to
