It matches the original voltage rail, connector, and BMS communication protocol. Capacity figure is taken directly from product specifications — 9000mAh at 25.2V nominal.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e4.0 Basic and Elite platform fit:\u003c\/strong\u003e\n    The 4.0 Basic, Basic 4WD, Elite, and Elite 4WD all share the same 25.2V battery bay, connector pinout, and BMS handshake. One pack covers all four variants without any adapter or wiring modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through blade-motor start sequences and navigation load transitions. The BMS held voltage within spec across both the drive motors and cutting deck draw without triggering overcurrent cutoff under normal grass conditions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage and first spring charge:\u003c\/strong\u003e\n    Before the first mow of the season, bring the battery indoors overnight if temperatures are below 10°C. Cold Li-ion cells carry higher internal resistance, and the blade motor inrush current on a cold pack can trip the BMS before the mower completes its first row.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff under thick grass or wet-lawn blade load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the cutting deck hits dense or wet grass, the blade motor draws a sharp inrush current that can spike well above normal running load. If the BMS reads this spike as an overcurrent event, it trips and the mower stops mid-row. This is more likely on a new or recently stored pack whose cells haven't settled into their working resistance. Running two or three shorter mow cycles on a freshly installed battery lets the cells condition before tackling a full heavy-load session.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger shows fault light after mower sat unused all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the battery discharged below roughly 20V during long storage, the charger's acceptance circuit may refuse to begin a charge cycle — indicated by a steady fault or red light with no current flow. This is a low-voltage lockout, not a dead pack. Place the battery in a warm room (above 15°C) for two hours, then reconnect the charger. Most packs recover and begin accepting charge once cell temperature stabilises above the BMS re-initialisation threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381315666010,"sku":"BWCS-ABL110VX-1","price":223.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381315698778,"sku":"BWCS-ABL110VX-2","price":266.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381315731546,"sku":"BWCS-ABL110VX-3","price":297.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ABL110VX-1.webp?v=1778899944","url":"https:\/\/batteryweb.com\/products\/ambrogio-40-basic-replacement-battery-252v-9000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
