I have 5 of these units - well, 2 x SP2000 and 3 x SP3000's and 4 have the dreaded BMS error. So I removed the BMS from (one of) the GBLI5001 batteries and fitted a third party unit, and was going to run them as lead, but now I've discovered I've lost all the NTC sensors for the units!
Does anyone have any I could have/buy? Google has been totally unhelpful and can't even provide a part number
Could I make my own? Buy a third party?
Since I won't actually be monitoring the temperature using these sensors (the BMS has it's own temperature sensor) could I simply wire in a variable resistor to the NTC input and adjust to find a resistance it's happy with?
Anyone know what the resistance is of one of the sensors at room temperature?
Separately, could I Y-in 2 batteries in parallel to the SP3000's? Would allow me to use off peak charging
Anyone have any NTC Sensors for old Growatt SP2000?

I wired up a variable resistor to the SP2000/SP3000's and it works!
For reference I used pins 2 and 8
