Hi folks,I'd like to 'emulate' a Greenworks 40v battery because I've a 40v Greenworks hedge trimmer (G40HT61) but am too mean to buy their battery and charger (too expensive imho). I have several 18v power tool batteries that could easily power it if I connect a pair in series but there's a minor problem. It runs for about 5 seconds then cuts out. It's likely that the control wire connecting the battery to the control pcb is the issue. It runs from the pin next to the minus terminal on the trimmer to the the PCB at a point marked "COM". The Greenworks battery will connect this wire to either the + or - terminal via some electronic component and I wondered what it might be, hence my query.
I've read that some cheaper 40v batteries are pin compatible - Kobalt, Snapper etccheers!k
