It fits the drill's battery bay and connects through the same contact plate as the factory unit. Voltage and cell format match the original so the charger handshake completes normally.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBAS 36 LI platform fit:\u003c\/strong\u003e\n    The Basic BAS 36 LI runs a 7.4V two-cell Li-ion architecture. This pack mirrors that cell configuration, so the BMS communication between pack and tool operates within the voltage thresholds the tool's motor controller expects.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated trigger-pull sequences to confirm the BMS handles motor-start inrush without tripping overcurrent protection. Cell voltage held stable across the discharge curve under variable load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMotor inrush run-in on first use:\u003c\/strong\u003e\n    On first use, run the tool at half load for two cycles before applying maximum torque. This lets the BMS log the motor's inrush current profile and set its overcurrent threshold accurately 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 overcurrent trip on trigger pull in the BAS 36 LI\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a cordless drill, the motor draws a brief inrush current spike — often three to five times the running current. On a new or freshly charged pack, the BMS may not yet have a calibrated threshold for this tool's specific motor. If the BMS reads the spike as a fault, it cuts output immediately and the tool goes dead on trigger pull. Running two half-load cycles first gives the BMS enough data to distinguish normal inrush from a genuine overcurrent event.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising the new pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells that sit in storage can drop below the charger's acceptance voltage — typically around 2.5V per cell. When the BAS 36 LI charger sees a pack below that threshold, it reads it as a fault and refuses to begin the charge cycle. Remove the pack, wait 60 seconds, and reinsert it to trigger a fresh handshake attempt. If the charger still won't engage, check each cell pair with a multimeter — any cell below 2.4V needs a recovery charge at a low current before normal charging can resume.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416071209050,"sku":"BWCS-BST200PW-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416071241818,"sku":"BWCS-BST200PW-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416071274586,"sku":"BWCS-BST200PW-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BST200PW-1.webp?v=1779760040","url":"https:\/\/batteryweb.com\/products\/meister-basic-bas-36-li-replacement-battery-74v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
