It restores wireless operation when the original cell has lost charge capacity. Dimensions are 55.10 × 33.40 × 24.60mm — measure your existing cell before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eErmila Bellina platform fit:\u003c\/strong\u003e\n    The Bellina runs a single LiFePO4 cell at 3.2V nominal. That flat discharge curve is intentional — LiFePO4 holds voltage steady under motor load longer than Li-ion, which suits the variable draw of a clipper motor during dense or coarse hair passes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and load discharge. The BMS held cutoff correctly at low-voltage threshold and accepted charge current without tripping protection. Cell temperature stayed within normal range across the discharge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePort drying before charge:\u003c\/strong\u003e\n    If the Bellina has been rinsed or used in humid conditions, dry the charging contacts completely before connecting the charger. Moisture bridging the contacts can trigger a BMS protection fault — the device then reports as a dead battery rather than a charging error.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eShaver motor speed dropping before the indicator shows low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLiFePO4 has a flat voltage curve, but an aged or degraded cell still sags under the short high-current spikes the Bellina motor produces during cutting resistance. The indicator reads state-of-charge from resting voltage — it hasn't updated yet when the motor is pulling current. The result is a speed drop that feels like a dead battery while the indicator still shows charge remaining. A fresh cell with full capacity eliminates this sag under load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCapacity drift from daily partial cycling on the Bellina\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLiFePO4 handles partial cycles better than Li-ion, but the Bellina's charge indicator calibration can still drift if the cell is never fully cycled. The gauge is calibrated against a full charge-to-cutoff reference point. Repeated top-ups without a complete discharge mean the indicator loses its baseline and starts cutting off earlier than the actual cell capacity warrants. Run the clipper to BMS cutoff once, then charge fully to 3.65V to reset the reference.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416128225370,"sku":"BWCS-MCP187SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416128258138,"sku":"BWCS-MCP187SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416128290906,"sku":"BWCS-MCP187SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MCP187SL-1.webp?v=1779760313","url":"https:\/\/batteryweb.com\/products\/ermila-bellina-replacement-battery-32v-1800mah-lifepo4","provider":"BatteryWeb","version":"1.0","type":"link"}
