I have used the switch and charged the batteries and its going well, haven't charged all the way yet because I don't have the inverter there to use some of that stored power, don't want to leave them sitting high, the SOC is not correct as expected on its first charge.
The switch port, sometimes this is unmarked and in different locations on other versions of BMS they just love to keep changing things.
Ok the BMS will wake up easily, thought it good to show a pic of it on the Phone APP, can see the fets turned off.
And now with the switch turned on, the green toggle's showing the fets on, still don't know if the BMS will do exactly as it supposed to, will have to test it with an over voltage cell trigger and see if the chg moss switches off.
I have to get the other BMS tool on the new laptop computer and find those settings, still not sure weather to change the switch option or use it this way, it would be good for a caravan or something very easy to isolate the batteries from the rest of the system, although startup procedure would have to be followed for the inverter and charge controller hope no one forgets it.
I'm sure there are a few on the DIY solar power forum that have been tricked up by this switch been enabled, would make people think the BMS is faulty or broken.
Still a lot of other work to do Early days yet.
