It fits the M4, M440, M480, M485, and additional models in the same series. The voltage and connector match the original pack so the mower's BMS handshake completes without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eM4 series compatibility:\u003c\/strong\u003e\n    The M4, M440, M480, and M485 all run the same 25.2V power rail and use the same battery bay connector. One replacement covers all models in this group without any adapter or rewiring.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through blade-start inrush cycles on M4-class mower loads. The BMS held across repeated high-draw starts and stepped down correctly at low-cell-voltage cutoff thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage tip:\u003c\/strong\u003e\n    Before the first mow of spring, 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 can trip the BMS on a cold pack before a single row is finished.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff on thick-grass or wet-grass blade load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWet or dense grass puts sustained high current through the blade motor, well above normal cutting load. If the pack is already warm from a previous run, the BMS thermal threshold can be reached faster than expected and the mower shuts down mid-row. This is a protection event, not a fault. Let the pack rest for at least five minutes in open air, then resume — the BMS resets automatically once cell temperature drops back inside the safe window.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger showing fault light after mower sat in garage all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly over months of storage. If a pack sits unpowered through winter, individual cells can drop below the charger's acceptance voltage — typically around 2.5V per cell — and the charger refuses to initiate a charge cycle, showing a fault or blinking red. Some chargers have a recovery or \"boost\" mode that applies a trickle current to bring cells back above the acceptance threshold. If your charger lacks that mode, a Li-ion recovery charger set to 25.2V at low current (0.1C) for 15–20 minutes is usually enough to bring the pack back into normal charge range.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381318090842,"sku":"BWCS-ABL110VX-1","price":223.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381318123610,"sku":"BWCS-ABL110VX-2","price":266.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381318156378,"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\/lizard-m4-replacement-battery-252v-9000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
