When the H30 runs sustained high-power mode against a blocked filter or dense carpet pile, current draw spikes past the protection circuit's threshold. The BMS cuts the motor to protect the cells, then resets once current demand drops. It can feel like an intermittent fault but the pattern is consistent — it happens under load, not at rest. Clear the filter, check the roller for tangled debris, and drop to standard suction mode on heavy carpet to stay below the trip threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426378219610,"sku":"BWCS-DRH310VX-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426378252378,"sku":"BWCS-DRH310VX-2","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426378285146,"sku":"BWCS-DRH310VX-3","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DRH310VX_1.webp?v=1779931068"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/collections\/BW-CS-HVS120VX_6.webp?v=1780022179","url":"https:\/\/batteryweb.com\/collections\/vacuum-batteries.oembed?page=99","provider":"BatteryWeb","version":"1.0","type":"link"}
