It fits the VX20 scanner unit used in aerial survey and terrain documentation missions. Voltage and cell count match the original specification — 10.8V nominal across a 3S Li-ion configuration.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVX20 platform fit:\u003c\/strong\u003e\n    The VX20 runs its LiDAR emitter, IMU, and GNSS receiver from a shared 10.8V rail. Any replacement pack must hold that voltage stable under simultaneous sensor load — a sag event mid-flight corrupts the point cloud timestamp sync.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack under sustained draw simulating concurrent LiDAR pulse and GNSS lock. The BMS held cutoff thresholds correctly and did not trip during the inrush current at sensor initialisation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePre-deployment calibration:\u003c\/strong\u003e\n    After fitting this pack, run a full calibration cycle through the VX20 system menu before the first flight. The instrument maps battery state during that sequence — skipping it causes premature low-battery warnings during your first mapping session.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eVoltage dropout under combined LiDAR and GNSS load mid-flight\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe VX20 pulls current from the same cell group for the laser emitter, IMU, and GNSS receiver simultaneously. On a degraded or deeply discharged pack, that combined draw causes a momentary voltage sag below the BMS protection threshold. The BMS interprets this as an over-discharge event and cuts output — the scanner shuts down mid-mission even though the state-of-charge indicator showed capacity remaining. A healthy pack at full charge holds above 11.1V under this combined load; if yours drops below 10.0V on the bus during a mission, the pack needs replacing.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eVX20 not recognising a new pack after the unit sat unused between survey seasons\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA Li-ion pack stored for several months without a maintenance charge can drop below the BMS recovery voltage — typically under 2.5V per cell, or roughly 7.5V total for a 3S pack. When the VX20 attempts to communicate with the battery management circuit at that voltage, the BMS does not respond, and the instrument reports no battery or refuses to power on. Connect the pack to its dedicated YellowScan charger for at least 30 minutes before attempting to power the scanner — most chargers have a recovery or wake mode that pulses low current to bring the cells above the re-initialisation threshold. If the charger LED does not advance past the fault state after one hour, the pack will not recover.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360453623898,"sku":"BWCS-FBP290SL-1","price":403.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360453656666,"sku":"BWCS-FBP290SL-2","price":483.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360453689434,"sku":"BWCS-FBP290SL-3","price":542.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FBP290SL-1.webp?v=1778614684","url":"https:\/\/batteryweb.com\/products\/yellowscan-scanner-radar-geographic-mapping-vx20-replacement-battery-108v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
