It replaces OEM part PA-L2 directly. The InControl 1050 is a portable analytical and measurement device used in professional lab and field survey work.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eInControl 1050 pack compatibility:\u003c\/strong\u003e\n    The PA-L2 footprint is specific to this instrument — 54.74 × 34.50 × 11.00mm with a connector and BMS handshake matched to the InControl 1050's power management circuit. Other Labotect packs from adjacent models do not share this profile.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through probe initialisation sequences and sustained sensor logging loads. The BMS held above the low-voltage cutoff threshold throughout, and charge acceptance was consistent across multiple cycles with no mid-session drops.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCalibration cycle before first field deployment:\u003c\/strong\u003e\n    After fitting this pack, run a full calibration cycle through the InControl 1050's instrument menu before taking it into the field. The instrument maps battery state during calibration — skipping this step causes premature low-battery warnings during your first measurement 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 InControl 1050 sat unused in a carry case for months\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly during storage. If the InControl 1050 sits unused long enough, the cell voltage drops below the BMS's minimum recovery threshold — typically around 2.5V for this chemistry. At that point, the BMS enters a protection state and blocks both charging and power-on. A standard charger will not recover the pack from this state because it cannot push current past the locked BMS. To recover, apply a trickle charge at a low current using a bench charger with a Li-ion recovery mode, bringing cell voltage up to at least 3.0V before switching to normal charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReadings drifting or resetting mid-session during a logging run\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSustained sensor load draws continuous current from the pack, and an aged or partially discharged cell will show a voltage dropout under that load even if the display showed a healthy charge at power-on. That momentary voltage sag is enough to trigger the instrument's under-voltage protection, causing a measurement reset or data interruption without a full shutdown. This is different from a BMS trip at probe power-up — it happens gradually under steady draw, not at the spike moment. If this occurs, charge the pack fully to 4.2V and recheck; if the sag persists on a fresh charge, the cell capacity has degraded and replacement is the correct fix.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360591052890,"sku":"BWCS-LTC105SL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360591085658,"sku":"BWCS-LTC105SL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360591118426,"sku":"BWCS-LTC105SL-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LTC105SL-1.webp?v=1778615988","url":"https:\/\/batteryweb.com\/products\/labotect-incontrol-1050-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
