It slots into the same battery bay as the original pack and communicates with the stock charger and BMS. No adapters or firmware changes needed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLynx and Puma platform compatibility:\u003c\/strong\u003e\n    The Lynx, Lynx RR, Puma, and Puma-RR share the same 18V battery rail, connector pinout, and BMS handshake protocol. One pack works across all four models without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated motor-start inrush events on an 18V drill platform. The BMS held the overcurrent threshold correctly and did not trip on a standard trigger pull under load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle load conditioning:\u003c\/strong\u003e\n    On first use, run the tool at half load for two cycles before applying maximum torque. This lets the BMS profile the motor inrush current draw and calibrate its overcurrent protection thresholds before you push the tool 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 motor-start inrush surge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a drill or driver under load, the motor draws a brief inrush spike — often three to five times the running current. A new pack fresh from storage has cells sitting at a lower state of charge, which raises internal resistance and amplifies that voltage drop at the rails. If the BMS sees the rail voltage dip below its cutoff threshold during that spike, it shuts the pack down as a protection event. Charge the pack to full before the first heavy-load use — a full charge lowers internal resistance and keeps the rail voltage above the BMS trip point during start surge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTool bogs under sustained load but recovers at idle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the tool feels weak or slows under cutting or driving pressure but snaps back when you release the trigger, the issue is voltage sag — not a dead battery. Under sustained current draw, internal resistance in the cells causes the output voltage to drop mid-use, starving the motor. Check the battery contact rails on both the pack and the tool for corrosion or debris — high contact resistance makes sag worse. Clean the contacts with isopropyl alcohol, reseat the pack firmly, and verify the rail voltage reads at or above 17.5V under no-load before use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416022450266,"sku":"BWCS-MTK570PX-1","price":116.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416022483034,"sku":"BWCS-MTK570PX-2","price":136.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416022515802,"sku":"BWCS-MTK570PX-3","price":152.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MTK570PX-1.webp?v=1779759485","url":"https:\/\/batteryweb.com\/products\/pressfit-lynx-replacement-battery-18v-6000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
