It slots into the original battery housing and connects to the same BMS circuit as the factory cell. At 38.48Wh, it matches the energy capacity of the original pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePara pool vacuum compatibility:\u003c\/strong\u003e\n    The Limpiafondos Para runs a 7.4V two-cell Li-ion architecture. This pack matches that voltage rail and uses the same connector and BMS handshake the charger expects — swapping in a different voltage or cell count will trigger a charge fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack under simulated pool vacuum motor loads and monitored BMS behaviour through startup and sustained suction. The protection circuit held stable through normal draw spikes and cut off cleanly at the low-voltage threshold without nuisance trips.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePool vacuum storage tip:\u003c\/strong\u003e\n    If the Para sits unused between pool seasons, discharge the battery to around 50% before storage. A fully charged Li-ion pack held at maximum state of charge for months accelerates cell degradation faster than use does.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSuction dropping before the battery indicator reaches low\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003ePool vacuums face a specific stress that dry-surface vacuums don't — debris and algae accumulate on the filter rapidly, restricting airflow mid-session. When the filter loads up, the motor works harder, draws more current, and voltage sags at the battery terminals. That sag reads as a low-charge condition to the motor controller, and suction drops even though the pack still has capacity. Clean the filter before each session and check that the debris canister isn't more than two-thirds full during operation.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery fade after leaving the Para on the charging dock continuously\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells degrade faster when held at 100% state of charge over extended periods — a common issue with pool cleaners that stay docked between weekly uses. The charger trickle-feeds the pack to keep it topped up, but sustained high-voltage storage stresses the cathode chemistry. After a full charge, unplug the vacuum and store it off the dock. If the pack no longer holds a usable charge after months of dock storage, this replacement cell starts the cycle fresh — charge fully, then remove from the charger at 7.4V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426378514522,"sku":"BWCS-WRP400VX-1","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426378547290,"sku":"BWCS-WRP400VX-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426378580058,"sku":"BWCS-WRP400VX-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WRP400VX_1.webp?v=1779931027","url":"https:\/\/batteryweb.com\/products\/limpiafondos-para-replacement-battery-74v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
