It replaces OEM part HYLB-1787 directly. The pack slots into the same bay and uses the same connector and BMS handshake as the original.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAE2300, AE2300H, and AE2300L compatibility:\u003c\/strong\u003e\n    These three variants share the same battery bay dimensions, connector pinout, and BMS communication protocol. One pack covers all three. The voltage rail and cell configuration are identical across the series, so the BMS handshake completes without error on any of them.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through probe initialisation cycles and sustained sensor load on the AE2300 platform. The BMS held voltage above the cutoff threshold during the current spike at probe power-up, and the instrument logged clean data throughout the test session without a dropout event.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst deployment on the AE2300:\u003c\/strong\u003e\n    After installing this pack, run a full calibration cycle through the instrument menu before heading into the field. The AE2300 maps battery state during calibration — skipping this step causes premature low-battery warnings on the 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 cutoff when the AE2300 probe module initialises\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the AE2300 powers up a probe or sensor module, there is a brief current spike as the module initialises. On a degraded or deeply discharged original pack, this spike pushes the instantaneous draw past the BMS overcurrent threshold, and the instrument shuts off immediately. This replacement pack uses cells rated for a higher peak discharge current, so the BMS does not trip during that initialisation window. If the instrument still shuts off at probe power-up after fitting this pack, check that the probe connector is clean and fully seated — a high-resistance connection amplifies the voltage sag at that moment.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAE2300 readings drifting or resetting mid-logging session\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDuring a sustained logging session, sensor load draws continuous current. If the pack's cells have degraded, internal resistance rises and the pack voltage sags below the instrument's stable-operation threshold under that steady load — even if the battery indicator still shows partial charge. The instrument interprets the voltage dropout as an instability event and resets the current measurement or drops the log entry. Fitting a fresh pack restores the voltage floor under load. After replacing the battery, confirm resting voltage is at or above 7.8V before starting a logging session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360496517210,"sku":"BWCS-DAE230SL-1","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360496549978,"sku":"BWCS-DAE230SL-2","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360496582746,"sku":"BWCS-DAE230SL-3","price":83.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DAE230SL-1.webp?v=1778615883","url":"https:\/\/batteryweb.com\/products\/deli-ae2300-replacement-battery-74v-4000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
