It powers the drive motors and control board that handle autonomous floor and wall cleaning cycles. Capacity matches the factory spec at 24.79Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVektro Z200 motor and control compatibility:\u003c\/strong\u003e\n    The Z200 runs a shared voltage rail feeding both the brushless drive motor and the navigation controller. Both systems draw from the same 7.4V cell, so any voltage sag under motor load hits the controller too — causing erratic path behaviour or mid-cycle shutdowns. This replacement holds the same cell configuration to keep both systems stable under load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full cleaning loads and monitored BMS response during sustained motor draw. The protection circuit held cutoff thresholds consistent with the OEM cell across repeated drain-and-charge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-cycle charging practice for pool robots:\u003c\/strong\u003e\n    After each cleaning cycle, charge the battery fully, then disconnect from the charger. The Z200 sits idle between pool sessions — leaving it on charge during that downtime accelerates capacity fade faster than normal cycling does.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Vektro Z200 loses suction pressure before the battery indicator drops\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Z200's impeller motor pulls more current when the filter mesh is partially blocked — even light debris buildup increases restriction. Under that elevated draw, cell voltage sags below the motor's efficient operating range while the indicator still reads mid-charge. The motor slows and suction pressure drops noticeably before the BMS triggers low-voltage cutoff. Rinse the filter after every session to keep motor draw within the cell's rated output band.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eZ200 cuts out mid-cycle then restarts on its own\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a failed battery. When the impeller encounters a sustained blockage — debris wedged against the intake or a clogged filter — current draw spikes past the protection circuit threshold and the BMS disconnects the load. The robot stops, the BMS resets after a few seconds, and the cycle resumes until the blockage triggers another trip. Clear the intake and filter, then check resting cell voltage — a healthy cell at partial charge should read above 7.0V after the trip recovers.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427960193114,"sku":"BWCS-BTF482VX-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427960225882,"sku":"BWCS-BTF482VX-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427960258650,"sku":"BWCS-BTF482VX-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BTF482VX-1.webp?v=1779933520","url":"https:\/\/batteryweb.com\/products\/kokido-vektro-z200-replacement-battery-74v-3350mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
