It powers the drive motors, suction fan, and onboard navigation electronics. Capacity figures come from our product data — 33.3Wh total energy storage.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVR100 and VX100 platform fit:\u003c\/strong\u003e\n    Both models share the same battery bay geometry, connector pinout, and BMS handshake protocol. The VX100 uses the same 7.4V voltage rail as the VR100, so one cell covers both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through charge and discharge cycles on a VR100 unit. The BMS communicated correctly with the charger, accepted a full charge without fault codes, and released current to the motor driver without tripping overcurrent protection.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for the VR100:\u003c\/strong\u003e\n    The VR100 returns to its dock automatically after every run. Left on the dock indefinitely between cleans, the battery stays at full voltage under trickle charge — a condition that accelerates capacity fade in Li-ion cells. Charge to full, then remove the dock's power until the next scheduled clean.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSuction dropping before the VR100 battery indicator shows low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe VR100's motor controller monitors cell voltage directly, not just state of charge percentage. When a degraded battery can't sustain voltage under the suction motor's load, the controller throttles fan speed to protect the circuit — even if the indicator still reads mid-range. A partially blocked filter compounds this: restricted airflow forces the motor to draw more current, which pulls cell voltage down faster. The result looks like a weak battery but is often a filter problem. Clean or replace the filter first, then retest — a healthy cell should hold above 7.0V under load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eVR100 stops mid-clean, pauses, then resumes on its own\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis stop-and-recover pattern is a BMS overcurrent trip, not a software fault. The BMS cuts current when the motor draws beyond its rated threshold — most often triggered by sustained suction restriction from a clogged filter or a partial blockage at the intake. The BMS resets itself after a short cooldown, which is why the robot appears to recover without user input. Clear any blockage at the brush roll and intake port, clean the filter, and check that the replacement battery's BMS is not tripping on normal motor-start current — a fresh cell should handle the start surge without cutting out.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428030840922,"sku":"BWCS-VKV100VX-1","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428030873690,"sku":"BWCS-VKV100VX-2","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428030906458,"sku":"BWCS-VKV100VX-3","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VKV100VX-1.webp?v=1779933918","url":"https:\/\/batteryweb.com\/products\/vorwerk-kobold-vr100-replacement-battery-74v-4500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
