Greetings good folk of Endless Sphere,
I've bought an 80V Stiga chainsaw (same as Kobalt and Greenworks) to replace my 50cc gas saw. I'm hoping to run it from my 20ah 22s ebike batteries to get proper cutting time and avoid spending a fortune on the little batteries that normally come with it.
I've succesfully converted my Stihl MSA200 to run from a 36V 20ah backpack battery, but ended up having to swap the speed controller to a 120a HV Castle Creations RC ESC. I love the saw for woodwork and small pruning jobs but needed more power to run a decent size bar and a full chisel chain hence I'm curious to see how the 80V saw will perform.
I've tried to connect my battery directly to the speed controller of the 80V Stiga saw using the positive and negative terminals and I'm managing to get a little spin from the motor but it quickly cuts out and starts beeping and flashing red light. The fault appears also when I connect the battery and let it sit for a bit after switching it on. The saw uses a third terminal with a black wire going to the speed controller from what I believe is a tab labeled with 'C' on the battery (one next to the negative terminal). I suspect the speed controller is expecting some sort of a signal from there to operate correctly and was wondering if there are any Greenworks/Cobalt/Stiga 80V users on the forums who could help me out. I would be most grateful if someone that owns the batteries could make an attempt to measure the output from that terminal.
All the best,
Uula
