I am not rally sure how to approach finding out what this connector is used for by the vacuum although I know some people in china have figured out what it is used for because there are knockoff batteries made for it and 3rd party battery bms boards on aliexpress:&nbsp;<a href="https://www.aliexpress.com/item/4000925832042.html?spm=a2g0o.productlist.0.0.37cf5bd6ky3Jc5&amp;algo_pvid=7ec7c5dd-ac9b-49b4-8009-10b451427240&amp;algo_exp_id=7ec7c5dd-ac9b-49b4-8009-10b451427240-2&amp;pdp_ext_f=%7B%22sku_id%22%3A%2210000011253922205%22%7D">BMS Battery Protection Board PCB Board for Dyson V10 US $291 sold+ Shipping: US $2.52US Electronic Technology Co.,LTD</a>. If anyone has a place to recommend starting I would greatly appreaciate it. I recently purchased an oscilloscope: GWInstek GDS-1102B, but I am a noob so I am not sure how I should use it best.</p> <p>Thanks in advance!</p> <p>Christopher</p><div style="clear:both;"></div>
