It fits the 967044601 40V 24\" cordless lawn mower and the 967044601 40V Dual Steel Hedge Trimmer 24\". Voltage, connector, and BMS communication match the original pack specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e967044601 platform compatibility:\u003c\/strong\u003e\n    Both the 24\" lawn mower and the dual steel hedge trimmer run off the same 40V rail with the same pack housing and connector pinout. The BMS handshake protocol is identical across both tools, so one pack serves either application without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through full charge-discharge cycles on a 40V load bench, monitoring BMS cutoff thresholds and cell voltage balance across the stack. Cell delta stayed within spec at end-of-discharge, and the protection circuit responded correctly to simulated overcurrent events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMotor inrush on first cycles:\u003c\/strong\u003e\n    On first use, run the mower or trimmer at partial throttle for two cycles before sustained full-load passes. This lets the BMS log the motor's inrush current signature and calibrate its overcurrent threshold before you push the deck through heavy grass.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS overcurrent trip on mower blade engagement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the 967044601 mower deck engages, the brushless motor draws a sharp inrush spike that can exceed the BMS overcurrent threshold on a cold or freshly installed pack. The BMS interprets that spike as a fault and disconnects the output rail before the blade reaches operating speed. A new pack from storage is more susceptible because the cells have not yet been profiled under this tool's load curve. Running two partial-load cycles first lets the BMS set a threshold that accommodates the deck motor's actual start current without false-tripping.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger shows blinking red and won't accept the pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA 40V pack stored for several months can drop below the charger's acceptance voltage — typically around 30V for a 10-cell series stack. The charger detects the low rail and refuses to enter normal charge mode, showing a blinking red fault light instead. Most Poulan Pro 40V chargers include a recovery or trickle mode: remove the pack, wait 60 seconds, then reinsert it firmly to trigger the recovery handshake. If the charger accepts the pack and moves to solid red, the cells are recovering; if the fault blinks persist after two attempts, check that pack terminal voltage reads at least 28V with a multimeter before trying again.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416011309146,"sku":"BWCS-GWP401PW-1","price":109.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416011341914,"sku":"BWCS-GWP401PW-2","price":128.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416011374682,"sku":"BWCS-GWP401PW-3","price":143.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GWP401PW-1.webp?v=1779759245","url":"https:\/\/batteryweb.com\/products\/poulan-pro-967044601-40v-24-replacement-battery-40v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
