It fits the Rotaflow Console, Table 702, and Table 755 configurations. Capacity is 120Wh, matching the OEM specification for the pump's motor drive and control electronics.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRotaflow platform compatibility:\u003c\/strong\u003e\n    The Console, Table 702, and Table 755 all share the same 24V battery rail and connector pinout. The BMS on each variant uses the same charge handshake protocol, so one replacement cell covers the full platform without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge acceptance and load discharge on a Rotaflow-class 24V bus. The BMS accepted the charge cycle without fault flags, and the protection circuit held within OEM voltage thresholds under simulated pump-motor load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test cycle:\u003c\/strong\u003e\n    After fitting this battery, let the Rotaflow complete its full power-on self-test without interrupting power. The BMS runs a verification sequence at startup to confirm cell chemistry and state of charge — cutting power mid-sequence causes a persistent false battery fault that only clears on a full reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Rotaflow BMS flags a fault on the first charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Rotaflow's charge IC applies a conservative current limit when it first encounters a new cell, because Ni-MH chemistry requires the BMS to profile internal resistance before it accepts a full charge. A fresh cell starts with slightly different impedance than a conditioned one. The BMS interprets this as a potential fault and may cap charge acceptance below 100% on the first cycle. One complete charge-to-discharge-to-charge cycle brings the cell within the BMS threshold and resolves the flag without any hardware intervention.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRotaflow not completing boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the Rotaflow stalls partway through its boot sequence after a battery replacement, the cause is usually the new cell sitting below the BMS minimum recovery voltage — common after storage. The BMS requires the pack to read above approximately 22V before it releases the boot sequence to the control board. Connect the unit to mains power and leave it on charge for a full cycle before attempting to boot on battery alone. Once the cell reaches the BMS recovery threshold, the boot sequence completes normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381416460378,"sku":"BWCS-MAT755MD-1","price":150.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381416493146,"sku":"BWCS-MAT755MD-2","price":178.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381416525914,"sku":"BWCS-MAT755MD-3","price":199.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MAT755MD-1.webp?v=1778900662","url":"https:\/\/batteryweb.com\/products\/maquet-rotaflow-centrifugal-pump-system-replacement-battery-24v-5000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
