It fits the iHand18 Data Collector and Qmini GPS handheld units. The iHand18 is a field GNSS receiver used in surveying and geospatial data collection — this pack keeps it running through site work when the primary battery runs out.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eiHand18 and Qmini GPS compatibility:\u003c\/strong\u003e\n    Both devices share the BL-2000A form factor, the same 7.4V two-cell Li-ion architecture, and an identical connector and BMS handshake. Swapping between units in a mixed fleet works without firmware changes or reconfiguration.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through GNSS acquisition sequences and sustained data-logging loads. The BMS held the output rail steady during satellite lock events and did not trip on the initialisation current draw that causes problems with lower-spec cells.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst deployment after installation:\u003c\/strong\u003e\n    Before heading into the field, run a full calibration cycle through the iHand18 instrument menu. The device maps battery state during calibration — skipping this step causes the low-battery warning to fire prematurely on the first survey 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 iHand18 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 iHand18 sits unused long enough, the cell voltage can drop below the BMS protection threshold — typically around 2.5V per cell. At that point the BMS opens the discharge circuit and the device appears completely dead, even on charge. The pack needs a slow pre-charge at low current to bring cells back above the recovery threshold before normal charging resumes. Use the original Hi-Target charger and leave it connected for at least two hours before assuming the pack is faulty.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eiHand18 shuts down mid-session during USB data transfer to PC\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eUSB data transfer combines active CPU load, display backlight, and the USB bus current draw simultaneously. On a partially degraded or cold cell, this combined load causes a voltage dropout that the BMS reads as a fault condition and cuts power to protect the cells. The shutdown happens suddenly — no low-battery warning. Check that the battery is above 7.0V before starting a transfer session. If it shuts down repeatedly at that step, the cell capacity has faded enough that the pack needs replacing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360449429594,"sku":"BWCS-TRH180SL-1","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360449462362,"sku":"BWCS-TRH180SL-2","price":90.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360449495130,"sku":"BWCS-TRH180SL-3","price":101.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TRH180SL-1.webp?v=1778614761","url":"https:\/\/batteryweb.com\/products\/hi-target-ihand18-data-collector-replacement-battery-74v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
