It slots into the same battery bay and connects to the same BMS interface as the original. Capacity matches the product data — 2000mAh, no inflation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eInvictus X3 and X5 compatibility:\u003c\/strong\u003e\n    All three models in this range share the same 21.6V voltage rail, identical battery bay dimensions, and the same BMS communication protocol. One pack covers the full Invictus lineup without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the Invictus X3 motor under both floor and carpet suction loads. The BMS held the voltage rail stable during high-draw carpet passes and tripped correctly when the airpath was deliberately restricted — no latent overcurrent faults detected.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for Invictus vacuums:\u003c\/strong\u003e\n    Do not leave this vacuum sitting on the charging dock indefinitely between uses. The Invictus dock delivers a maintenance charge that causes measurable capacity fade over months. Charge fully, then remove the vacuum from the dock until the next session.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCordless vacuum losing suction before the battery indicator reaches low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the Invictus X3 and X5, suction drops noticeably before the LED battery indicator signals low charge. This happens because the motor draws peak current under restricted airflow — a partially blocked filter forces the motor to work harder, pulling voltage down faster than the indicator updates. The BMS reads this as normal load and does not trigger a low-battery alert. Clean or replace the filter first; if suction recovers immediately, the battery was not the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean then restarts after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When the Invictus motor sustains a restricted suction path — hair wrap around the brush roll or a clogged filter — current draw spikes above the BMS threshold and the pack shuts output to protect the cells. The few-second pause is the BMS resetting. Clear the blockage, then restart the vacuum. If trips continue on a clear airpath, check that the pack voltage reads at least 20V under no-load before suspecting a cell fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426376515674,"sku":"BWCS-GNX500VX-1","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426376548442,"sku":"BWCS-GNX500VX-2","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426376581210,"sku":"BWCS-GNX500VX-3","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GNX500VX_1.webp?v=1779931068","url":"https:\/\/batteryweb.com\/products\/genius-invictus-x3-replacement-battery-216v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
