It slots into the same battery bay as the original SBT 2580AE, SBT 4080 AE, and SBT 5080 AE packs. The BMS communicates with the mower's motor controller at the same handshake voltage as the factory unit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAE platform compatibility:\u003c\/strong\u003e\n    The Combi 43 AE, 43 S AE, 48 AE, and 50 S AE share the same 80V battery rail and connector pinout. The BMS on each model expects the same cell voltage thresholds and state-of-charge signal — this pack meets those requirements without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on a Combi 43 AE under simulated blade load. The BMS held its cutoff threshold correctly during inrush, delivered consistent voltage through discharge, and triggered low-cell protection at the expected floor voltage without nuisance tripping.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst use of the season:\u003c\/strong\u003e\n    Before your first spring cut, bring the battery indoors overnight if temperatures are below 10°C. Cold Li-ion cells carry higher internal resistance, and the blade motor's inrush current at startup can trip the BMS on a pack that hasn't warmed to room temperature.\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 and wet-lawn blade load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Stiga AE mower draws its heaviest current at the moment the blade engages dense or wet grass. That inrush spike can briefly exceed what the BMS permits if the cells are cold or partially discharged. The BMS reads this as an over-current event and shuts the pack down to protect the cells. Starting with a fully charged, room-temperature pack significantly reduces the chance of a nuisance trip in heavy cutting conditions.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger showing a fault light after the mower sat all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly over months of garage storage. If the pack drops below roughly 2.5V per cell, most chargers refuse to begin a charge cycle — the fault LED is the charger rejecting a pack it reads as critically under-voltage. Some Stiga chargers include a recovery mode: remove the pack, wait 60 seconds, reinsert it, and watch for the charge LED to switch from fault to charging. If the fault persists after two attempts, the cells have dropped too far for safe recovery and the pack needs replacing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381304590426,"sku":"BWCS-GWP800PX-1","price":150.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381304623194,"sku":"BWCS-GWP800PX-2","price":178.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381304655962,"sku":"BWCS-GWP800PX-3","price":199.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GWP800PX-1.webp?v=1778899964","url":"https:\/\/batteryweb.com\/products\/stiga-combi-43-ae-replacement-battery-80v-4000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
