It fits the YRH300 directly and restores full power to the infrared detector, display, and image processing system. Capacity is 2200mAh (16.28Wh) — identical to the factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eYRH300 power rail match:\u003c\/strong\u003e\n    The YRH300 runs its IR detector heating element, LCD display, and onboard processor from the same 7.4V cell. Any deviation in voltage or BMS communication trips the camera's protection circuit. This pack meets that voltage floor and communicates correctly with the camera's charge management system.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the YRH300's full power-on sequence — detector warm-up load, active scan mode, and image capture bursts. The BMS held stable across the combined draw without triggering low-voltage cutoff prematurely.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDetector calibration tip:\u003c\/strong\u003e\n    Allow 60 seconds after power-on before starting any measurement. The YRH300's uncooled IR detector needs the internal electronics to reach thermal equilibrium first — skipping this step introduces baseline drift that throws off temperature readings 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\"\u003eWhy the YRH300 shuts down mid-inspection on a seemingly charged battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe YRH300 runs a continuous detector heating element alongside the display backlight and processor. That combined draw creates brief current spikes that exceed what a degraded or partially discharged cell can deliver. The BMS reads this as an undervoltage event and cuts power to protect the pack — even if the battery indicator still shows two bars. A fresh cell with adequate capacity sustains the combined load without the voltage dipping below the BMS trip threshold, which sits around 6.0V under load for this pack.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eThermal accuracy degrading before the low-battery warning appears\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe YRH300's IR detector is voltage-sensitive — its temperature reference circuit begins losing accuracy as cell voltage sags below approximately 6.8V, which happens well before the camera flags a low-battery warning. You'll see this as temperature readings drifting 2–4°C from actual values, or hot spots appearing slightly cooler than expected. The display and processor continue running fine at that voltage, so the camera feels operational while thermal data is already compromised. If readings seem inconsistent during a session, check battery voltage directly — swap the pack before it drops below 7.0V under load to maintain measurement integrity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426127675482,"sku":"BWCS-MSE500SL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426127708250,"sku":"BWCS-MSE500SL-2","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426127741018,"sku":"BWCS-MSE500SL-3","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MSE500SL-1.webp?v=1779930385","url":"https:\/\/batteryweb.com\/products\/dali-yrh300-replacement-battery-74v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
