The internal BMS removes the need for a separate protection board, so the battery presents a simple two-terminal connection to the rest of the system.\u003c\/p\u003e\u003cp\u003eAt 20Ah it suits smaller auxiliary loads: lighting circuits, instrumentation, communication equipment and similar 12V DC circuits. The M5 terminals accept standard ring terminals used in marine and automotive wiring.\u003c\/p\u003e\u003cp\u003eEach SuperPack operates as a standalone unit. Victron does not design this battery for series or parallel connection with other units; a different battery from the range with external BMS support should be chosen for larger capacity needs.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAuxiliary battery for marine vessels, covering navigation lights, instruments and VHF radio\u003c\/li\u003e\n\u003cli\u003eLightweight 12V house battery for touring caravans\u003c\/li\u003e\n\u003cli\u003eCampervans and motorhomes with limited battery compartment space\u003c\/li\u003e\n\u003cli\u003eOff-grid lighting and small DC load circuits\u003c\/li\u003e\n\u003cli\u003ePortable power stations and field equipment\u003c\/li\u003e\n\u003cli\u003eBackup power for 12V control systems and communications equipment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eInstallation notes\u003c\/h3\u003e\u003cp\u003eThe internal BMS manages cell-level protection, but the charger used still needs to suit LiFePO4 voltage profiles, with an absorption voltage of 14.2V and float of 13.5V. Do not connect this battery in series or parallel with other units. On boats, secure it against movement and keep terminals protected from moisture. Installation should be carried out by someone familiar with lithium battery systems.\u003c\/p\u003e\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e1x Victron Lithium SuperPack 12.8V\/20Ah (M5) battery\u003c\/li\u003e\u003c\/ul\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":52095613894944,"sku":"BAT512020705","price":130.17,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1010\/8148\/1504\/files\/ledandsolar-bat512020705-1.webp?v=1785756227","url":"https:\/\/www.ledandsolar.co.uk\/products\/victron-superpack-lifepo4-20ah-battery","provider":"LED \u0026 Solar","version":"1.0","type":"link"}
