It replaces OEM part number ND2054. The IMS-5 is a professional field measurement device, and this pack restores full operating voltage to the instrument's power rail.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIMS-5 power rail compatibility:\u003c\/strong\u003e\n    The IMS-5 runs a 14.4V nominal rail with a BMS handshake that checks cell count and voltage signature at power-on. This pack uses the same 4S Li-ion cell arrangement and connector pinout as the OEM unit, so the instrument clears that handshake and boots normally.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through power-on cycles and sustained sensor load draws. The BMS held stable under the current spike at probe initialisation and did not trip into protective cutoff during logging sessions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use calibration cycle:\u003c\/strong\u003e\n    After installing this pack, run a full calibration cycle through the IMS-5 instrument menu before field deployment. The instrument maps battery state during calibration — skipping this step causes premature low-battery warnings during your first measurement session, even when the pack is fully charged.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff when the IMS-5 probe module initialises\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the IMS-5 powers up a connected probe module, the instrument draws a short, sharp current spike to initialise the sensor. A degraded or deeply discharged pack can drop below the BMS undervoltage threshold during that spike, tripping protective cutoff before the instrument even reaches its home screen. This is a battery-side failure, not a probe fault. A fully charged pack at 16.4V should absorb that spike without the BMS cutting out.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eIMS-5 showing inconsistent battery percentage after every reboot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you swap in a new Li-ion pack, the IMS-5's voltage-threshold indicator has no charge history to work from and estimates state-of-charge from resting voltage alone. This produces erratic percentage readings — often jumping between values across reboots — until the instrument logs a full discharge and recharge cycle. Run the pack down through normal field use, then charge it fully without interruption. After that cycle, the percentage display stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360456933466,"sku":"BWCS-SND205MD-1","price":87.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360456966234,"sku":"BWCS-SND205MD-2","price":103.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360456999002,"sku":"BWCS-SND205MD-3","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SND205MD-1.webp?v=1778615901","url":"https:\/\/batteryweb.com\/products\/iguide-ims-5-replacement-battery-144v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
