Yes, sorry.
I bought the ESC like this (https://www.ebay.com/itm/RC-ESC-20A-Brush-Motor-Speed-Controller-w-Brake-for-RC-Car-Boat-Tank-BA/122513965979?hash=item1c8666c39b:g:eT4AAOSwEzxYd24R) but it comes without user manual so I don't know how to go through an arming process. I bought battery (https://www.ebay.com/itm/1pcs-7-2V-3800mAh-NiMH-Rechargeable-Battery-Tamiya-Plug-RC-Battery-Charger-USA/122703237415?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649) though it was good for this ESC in datasheet but my first ESC was smoked with this battery so I use 3.7V LiPo battery from other device. I use this with Arduino UNO powered from USB.
I connected it as shown on pic
