The BLK2GO captures real-time point clouds and LiDAR data on active job sites — a battery failure mid-scan means lost data and a return trip. This pack restores full scan sessions without pulling the unit from rotation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBLK2GO platform fit:\u003c\/strong\u003e\n    The BLK2GO uses a regulated 7.4V rail to power the spinning LiDAR mirror array, IMU, and onboard compute simultaneously. The GEB821 form factor locks this specific cell configuration and connector into that power envelope — any deviation in voltage or connector pinout causes the scanner to reject the pack at startup.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through BLK2GO power-on and active scan load cycles. The BMS held stable across the IMU initialisation spike and sustained sensor draw, and the scanner's battery indicator tracked state-of-charge correctly through the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the BLK2GO:\u003c\/strong\u003e\n    After fitting this pack, run a full calibration cycle through the BLK2GO instrument menu before field deployment. The scanner maps battery state during calibration — skipping this step causes premature low-battery warnings to appear during your first scan session, even with a fully charged pack.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS lockout after the BLK2GO sat unused in a carry case for months\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells in storage self-discharge slowly. If the BLK2GO and its battery sat dormant long enough, the cell voltage can drop below the BMS recovery threshold — typically around 2.5V per cell. At that point the BMS locks the pack into a protection state and the scanner will not power on at all, even when placed on charge. A standard charger may not deliver enough trickle current to pull the pack back above the recovery threshold. Connect the pack to a compatible Leica charger and leave it for at least 30 minutes before attempting to power the scanner — most packs recover once cells reach 3.0V per cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBLK2GO display showing inconsistent battery percentage after fitting a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BLK2GO's battery indicator is calibrated against the discharge curve of the original GEB821 cells. When a new pack is installed, the scanner's internal voltage-threshold mapping hasn't yet seen a full charge-discharge cycle on the new cells, so the percentage reading jumps or reads low relative to actual capacity. This is not a fault in the pack — it's the instrument recalibrating its reference points. Run two complete charge and discharge cycles through normal scanning use, and the percentage display will stabilise to accurate readings by the third cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360435863642,"sku":"BWCS-LCK821SL-1","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360435896410,"sku":"BWCS-LCK821SL-2","price":90.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360435929178,"sku":"BWCS-LCK821SL-3","price":101.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LCK821SL_1.webp?v=1778614685","url":"https:\/\/batteryweb.com\/products\/leica-blk2go-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
