The dual-cell 2S1P configuration delivers 5.18Wh from a 45.30 × 25.00 × 16.50mm footprint — physically matched to the original cavity. Check your existing pack for the part number before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e2S1P dual-cell architecture:\u003c\/strong\u003e\n    Two cells in series produce the 7.4V nominal rail. No parallel cells means the pack BMS monitors a simpler topology — any single-cell imbalance will trigger protection cutoff before the device loses power abruptly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran charge and discharge cycles on this pack using a calibrated cell analyser. The BMS responded correctly to overcharge and over-discharge thresholds, and cell balance stayed within 20mV across both cells at full charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration tip:\u003c\/strong\u003e\n    If your device has a fuel gauge or capacity indicator, run one full charge-discharge cycle immediately after installation. The gauge IC needs to measure the new cells from full to empty to reset its internal state of charge estimate.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePack running at lower voltage than rated on first install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer packs ship at storage voltage — typically 3.7V to 3.85V per cell, putting the 2S pack around 7.4V to 7.7V rather than the full 8.4V charge ceiling. This is intentional. Shipping at full charge accelerates cell degradation in transit. Charge the pack fully before first use and the device will read normal operating voltage.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice firmware rejecting the pack after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome compact devices run a voltage-range check or BMS handshake on startup. If the incoming pack sits below the device's minimum acceptance threshold — common when a storage-voltage pack reads around 7.5V — the firmware flags it as a fault. Connect the pack to its OEM-compatible charger first, bring it to full charge, then reseat it. Power-cycle the device after reseating to re-trigger the acceptance check.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333495750746,"sku":"BWCS-CM015SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333495783514,"sku":"BWCS-CM015SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333495816282,"sku":"BWCS-CM015SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CM015SL-1.webp?v=1778212808","url":"https:\/\/batteryweb.com\/products\/custom-battery-pack-replacement-battery-74v-700mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
