It restores full operating voltage to the drive motors and suction system after the original cell capacity has degraded. Fits MT820, Hovo 700, Hovo-700-1703, and Hovo-700-1610 platforms.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMT820 and Hovo 700 platform fit:\u003c\/strong\u003e\n    These models share the same 14.4V battery rail, connector pinout, and BMS handshake protocol — the same pack runs across all variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full discharge and recharge on the MT820 platform. The BMS held within spec under both normal floor-cleaning draws and the higher current spikes that occur when the brush roller contacts debris or transitions to carpet.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on robot vacuums:\u003c\/strong\u003e\n    Do not leave the MT820 sitting on the charging dock continuously. These units trickle-charge when docked and the cell has no way to stop it — charge to full, then remove the unit from the dock until the next use.\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 on the MT820\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe MT820's suction motor pulls significantly more current when the filter is partially blocked or the brush roller is restricted. A degraded or partially discharged cell cannot sustain voltage under that elevated load, so suction weakens while the indicator still reads mid-charge. The BMS is protecting the cell from a voltage drop below its low-cell threshold — not misreporting charge level. Clean the filter and check the brush roller before assuming the battery is at fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean and then recovers after a pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When the suction path is restricted — blocked filter, tangled brush, or carpet fibres bridging the inlet — the motor draws current above the pack's continuous discharge rating and the BMS interrupts output. Clearing the blockage and waiting 20–30 seconds allows the BMS to reset and resume normal output. If the cutout happens on an unblocked floor, confirm the replacement pack is fully charged to 14.4V before the next run.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427995222106,"sku":"BWCS-IFT820VX-1","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427995254874,"sku":"BWCS-IFT820VX-2","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427995287642,"sku":"BWCS-IFT820VX-3","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IFT820VX-1.webp?v=1779933799","url":"https:\/\/batteryweb.com\/products\/infinuvo-mt820-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
