It fits the Kimo 6 Inch Cordless Chainsaw and compatible models including QM-6001, QM-T20, and QM-3061B. When the original pack loses charge capacity or fails to hold voltage under load, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eQM-series platform compatibility:\u003c\/strong\u003e\n    The QM-6001, QM-T20, QM-3061B, and related Kimo chainsaws share the same 20V battery rail, connector pinout, and BMS handshake protocol — which is why one pack covers the full lineup.\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 20V motor load and confirmed the BMS engages overcurrent protection correctly on inrush spikes, holds the voltage rail stable mid-cut, and terminates charge cleanly at 21V.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use motor profiling:\u003c\/strong\u003e\n    Run the chainsaw at half load for two cycles before tackling maximum-diameter cuts. This lets the BMS log the motor's inrush current signature and calibrate overcurrent thresholds before you push it hard.\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 chainsaw motor-start inrush surge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a brushed or brushless chainsaw motor, the initial inrush current spike can be two to four times the running current. A new battery straight from storage has a cold BMS with no inrush profile stored — it may read that spike as a fault and cut the output immediately. Running two half-load cycles first lets the BMS distinguish a normal start surge from a true overcurrent event. After those cycles, the pack handles full-speed trigger pulls without tripping.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger blinking red on this pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells stored for several months can self-discharge below the charger's acceptance voltage — typically under 2.5V per cell. Most Kimo chargers refuse to begin a full charge cycle on a pack reading below that threshold, so the LED blinks red and nothing happens. Place the battery on the charger, wait 10–15 minutes, then remove and re-seat it — some chargers run a trickle pre-charge pulse that brings the cells up to acceptance voltage on that first contact. If the charger still rejects the pack after two attempts, check cell voltage directly; anything above 2.5V per cell (10V total on a 4S pack) should begin charging normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416011636826,"sku":"BWCS-KMK811PW-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416011669594,"sku":"BWCS-KMK811PW-2","price":94.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416011702362,"sku":"BWCS-KMK811PW-3","price":104.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KMK811PW-1.webp?v=1779759485","url":"https:\/\/batteryweb.com\/products\/kimo-6-inch-cordless-chainsaw-replacement-battery-20v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
