    New 80 volt push mowers

    I already looked around with that. I think that Greenworks motor have hall-sensors and self-propelled with it, also plus shipping out is $100, the rest of them are out of stocks. Not too crazy, but that is not what I am trying to achieve anyway.

    New 80 volt push mowers

    I bought another new battery to test it. It does exactly the same: "run 3s, then beep-beep-beep ... beep-beep-beep" I bought this mower out from a liquidation pallet.

    New 80 volt push mowers

    Thank you very much for you response again. I have learned a lot for the last 2 days. :D In some other Kobalt models, they use "a 3ph Permanent Magnet motor with hall effect rotor position sensors."

    New 80 volt push mowers

    My mower just stopped working (no warranty, bought used). Right now, it ran and then started beeping repeatedly. So I used another battery to test if it was a defectives battery.
