It replaces OEM part numbers 159904-0001, 163467-0001, MX7A380BATT, MX7382BATT, MX7392BATT, MX7394BATT, and 161772-0001. The TECTON MX7 is a rugged mobile computer used across warehouse, retail, and logistics operations.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMX7 platform compatibility:\u003c\/strong\u003e\n    All listed OEM part numbers share the same 7.4V two-cell configuration, connector pinout, and BMS handshake used across the TECTON MX7 series. Swapping between these part numbers does not require firmware changes or dock recalibration.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through combined scan-trigger and Wi-Fi radio load to confirm the BMS holds the 6.0V low-voltage cutoff without premature tripping. Cell balance across both cells stayed within 30mV through full discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift cradle protocol:\u003c\/strong\u003e\n    After installing the pack, seat it in the charging cradle for a complete charge cycle before running pick-and-pack. The scan trigger draws highest inrush current when the cell is near minimum — a fully charged pack prevents false BMS trips during the first shift.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCradle showing charging error on a new MX7 pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe TECTON MX7 cradle reads pack state through the dock's gold contact strip. Oxidation or residue on the battery contact pads raises resistance enough for the dock to flag a fault before charging begins. Wipe the battery contacts with a dry lint-free cloth and reseat the pack firmly until the dock LED changes. If the error clears, the pack was seated correctly — the fault was contact resistance, not a bad cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner losing wireless connection during rapid scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRapid sequential scanning combines imager power draw with active Wi-Fi polling, producing combined current spikes that can exceed 2A on a degraded or low cell. When cell voltage sags below the BMS threshold under that combined load, the radio drops before the scan engine does. This shows up as a mid-shift connection loss that clears when the trigger is released. Keep the pack above 30% charge during high-frequency scan runs to prevent the voltage sag that triggers radio dropout.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324806365274,"sku":"BWCS-LMX700BX-1","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324806398042,"sku":"BWCS-LMX700BX-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324806430810,"sku":"BWCS-LMX700BX-3","price":57.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LMX700BX-1.webp?v=1778123184","url":"https:\/\/batteryweb.com\/products\/honeywell-txe-tecton-mx7-replacement-battery-74v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
