It powers the unit through field data collection, GNSS logging, and stake-out sessions where access to a charger is limited. Voltage and capacity match the factory specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTSC3 and Ranger 3 platform compatibility:\u003c\/strong\u003e\n    The TSC3 and Ranger 3 family share the same battery bay geometry, contact rail, and BMS handshake protocol. One cell pack covers all variants in this line — the controller reads charge state through the same three-wire communication each time.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on a TSC3 unit under combined GPS receiver and display load. The BMS held the discharge curve within spec and tripped protection correctly at the low-voltage threshold without triggering a false shutdown mid-session.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-deploy calibration on the TSC3:\u003c\/strong\u003e\n    After fitting a new pack, run a full charge, then let the TSC3 discharge normally through a working session before recharging. The controller maps battery state across that first full cycle — skipping it causes the status indicator to report inaccurate percentages for the first several days of field use.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTSC3 shutting down the moment the internal GNSS receiver locks on\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the TSC3 activates its internal receiver, current draw jumps sharply as the RF front-end and correlator circuits spin up. An aged or deeply discharged cell can't sustain that spike without voltage sagging below the BMS cutoff threshold. The controller interprets this as a critically low battery and shuts down, even if the status bar showed 40% moments before. A fully charged, fresh cell absorbs that initialisation surge without a voltage drop large enough to trip the BMS.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTSC3 won't charge after sitting unused in a carry case for several months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells left in storage self-discharge slowly, and the Trimble BMS enters a sleep state once cell voltage drops below roughly 2.5V per cell — around 7.5V for this 3S pack. In that state the charger sees no handshake and refuses to begin a charge cycle. To recover the pack, apply charge through the TSC3's cradle or USB-C dock for at least 15 minutes continuously — many chargers will initiate a trickle pre-charge that brings the cells back above the wake threshold. If the charge indicator does not activate after 20 minutes, cell voltage has likely fallen below recoverable range.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360668614746,"sku":"BWCS-TRS300SL-1","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360668647514,"sku":"BWCS-TRS300SL-2","price":68.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360668680282,"sku":"BWCS-TRS300SL-3","price":75.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TRS300SL-1.webp?v=1778616177","url":"https:\/\/batteryweb.com\/products\/trimble-tsc3-replacement-battery-111v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
