It matches OEM part number 1ICP10\/40\/46-2 and fits directly into the Pico 4 headset housing. Swap it in when your original cell no longer holds a charge or has degraded after extended use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePico 4 compatibility:\u003c\/strong\u003e\n    The Pico 4 runs its display, Snapdragon XR2 processor, and 6DoF tracking cameras off a single cell. The 1ICP10\/40\/46-2 part number covers all Pico 4 units — the BMS handshake, connector pinout, and cell geometry are consistent across the production run.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell under combined display and processor load. The BMS held voltage above 3.6V through the draw cycle and triggered protection cutoff cleanly at the low-voltage threshold — no false trips under normal headset operation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSession voltage management:\u003c\/strong\u003e\n    The Pico 4's tracking processors draw harder when running room-scale scenes with multiple anchors active. Start sessions with a full charge — the tracking subsystem needs a stable voltage floor. A partially charged cell can sag enough under peak tracking load to cause drift events even before the headset reports low battery.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Pico 4 loses tracking when battery drops below 20%\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Pico 4's inside-out tracking relies on four camera feeds being processed in real time by the Snapdragon XR2. That compute load is constant — it doesn't scale back when battery gets low. As the cell voltage sags toward 3.6V, the processor throttles to protect thermals, and frame processing for the tracking cameras slows down. The result is drift, stuttering anchors, or brief tracking loss — even though the headset hasn't shut down yet. Keeping charge above 20% keeps cell voltage high enough to sustain full tracking throughput.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHeadset shuts down without warning mid-session\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the combined draw from the display, wireless, and processor hits the cell at the same moment — typically during a scene transition or when a new environment loads. The instantaneous current spike pulls cell voltage below the BMS cutoff threshold, and the headset powers off to protect the cell. A degraded original battery with high internal resistance is most vulnerable to this. If the replacement cell shows the same behaviour, verify the headset's charge port is clean and the cell seated fully — then charge to 100% and retest before assuming a fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428091101274,"sku":"BWCS-PCO400SL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428091134042,"sku":"BWCS-PCO400SL-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428091166810,"sku":"BWCS-PCO400SL-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PCO400SL-1.webp?v=1779934037","url":"https:\/\/batteryweb.com\/products\/pico-4-replacement-battery-385v-5300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
