Below about 11 volts an Auto-Level control panel starts to misbehave, and at 10.5 volts it stops. Some lithium batteries cannot supply the running amperage and surge these pumps draw, so check with the battery supplier.\u003c\/p\u003e\u003ch4\u003eDocuments\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/cdn\/shop\/files\/EQS03R11-EQ-Systems-Trailer.pdf\" target=\"_blank\"\u003eEQ Systems Lifting Systems for Any Size Trailer (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/cdn\/shop\/files\/Required-Maintenance-Items-Hydraulic-Systems-EQ-TM.pdf\" target=\"_blank\"\u003eRequired Maintenance Items for EQ Systems Hydraulic Jacks and Slide Systems (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EQ Systems","offers":[{"title":"Default Title","offer_id":43958756114491,"sku":"8400","price":397.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0690\/2608\/6971\/files\/8400-RVU-scaled.webp?v=1786537100","url":"https:\/\/eqsystems.us\/products\/stay-charge","provider":"EQ Systems","version":"1.0","type":"link"}
