The Freestyler is a dual-blade handheld tool that switches between a grass trimming blade and a hedge clipping blade. One battery powers both modes, so keeping a replacement on hand matters.\u003c\/p\u003e\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFits Freestyler and 9668616-01:\u003c\/strong\u003e Both models share the same 3.6V single-cell architecture, connector type, and BMS communication protocol — one pack covers both.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e We ran full charge\/discharge cycles — the BMS held voltage steady under load across both blade attachments and cut off cleanly at the low-voltage threshold without requiring a manual reset.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after storage:\u003c\/strong\u003e Li-ion cells at low state of charge can trigger a false protection lockout — always run a full charge cycle before first use to let the BMS calibrate correctly.\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003chr class=\"bpw-desc-divider\"\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy cell capacity matters in a single-cell 3.6V pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Freestyler runs on one Li-ion cell — there is no parallel cell arrangement to buffer load spikes. At 2400mAh, the cell needs to handle the full current draw alone when cutting through thicker hedge growth. The BMS here provides overcurrent protection specifically sized for that single-cell load profile. Undercapacity cells in this format show voltage sag quickly, which the tool reads as a depleted pack.\u003c\/p\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTool powers on but stops cutting under light load — what causes it\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is usually the BMS tripping on voltage sag, not a blade or motor fault. Aged or undercapacity cells drop below the protection threshold the moment any real cutting load is applied. The tool interprets this as an end-of-discharge condition and shuts the output. Swapping to a fresh-capacity pack at the correct 3.6V rating resolves this immediately.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43175812497498,"sku":"BWCS-FYM966VX-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43175812530266,"sku":"BWCS-FYM966VX-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43175812563034,"sku":"BWCS-FYM966VX-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FYM966VX-1.webp?v=1775236243","url":"https:\/\/batteryweb.com\/products\/flymo-freestyler-replacement-battery-36v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
