It includes a built-in battery management system (BMS), making it a self-contained drop-in solution for 12V systems. Suited to professional installers and system integrators working on space-constrained or weight-sensitive installations.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eLithium iron phosphate (LiFePO4) chemistry offers a significantly longer cycle life compared to lead-acid alternatives.\u003c\/li\u003e\n  \u003cli\u003eBuilt-in BMS provides cell balancing, over-charge, over-discharge, short-circuit, and over-temperature protection without requiring external components.\u003c\/li\u003e\n  \u003cli\u003eNominal voltage of 12.8V with 20Ah capacity, giving 256Wh of usable energy in a compact form factor.\u003c\/li\u003e\n  \u003cli\u003eM5 terminal connection for secure, low-resistance cable attachment.\u003c\/li\u003e\n  \u003cli\u003eLow self-discharge rate makes it suitable for seasonal or standby applications.\u003c\/li\u003e\n  \u003cli\u003eWeight of 3.3kg, considerably lighter than an equivalent lead-acid battery.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe SuperPack range from Victron Energy uses LiFePO4 cells, which are the most thermally stable lithium chemistry available for energy storage. Unlike lithium-ion chemistries, LiFePO4 does not present the same thermal runaway risk, making it a practical choice for enclosed spaces such as boat bilges, vehicle cabinets, and caravan battery compartments. The integrated BMS means no separate protection board is required, reducing installation complexity and potential points of failure.\u003c\/p\u003e\n\n\u003cp\u003eAt 20Ah, this battery is well suited to smaller auxiliary loads: lighting circuits, instrumentation, communication equipment, and similar 12V DC applications. The M5 threaded terminals accept standard ring terminals and are compatible with typical marine and automotive cable lugs. Because the BMS is internal, the battery presents a clean two-terminal interface to the rest of the system, simplifying wiring.\u003c\/p\u003e\n\n\u003cp\u003eVictron's SuperPack batteries are not designed for parallel or series connection. Each unit operates as a standalone battery. For larger capacity requirements, a different battery from the Victron range with external BMS support should be specified instead.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: BAT512020705\u003c\/li\u003e\n  \u003cli\u003eNominal voltage: 12.8V\u003c\/li\u003e\n  \u003cli\u003eCapacity: 20Ah (256Wh)\u003c\/li\u003e\n  \u003cli\u003eChemistry: Lithium Iron Phosphate (LiFePO4)\u003c\/li\u003e\n  \u003cli\u003eTerminal type: M5\u003c\/li\u003e\n  \u003cli\u003eWeight: 3.3kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076047537\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eAuxiliary battery for marine vessels (navigation lights, instruments, VHF radio)\u003c\/li\u003e\n  \u003cli\u003eLeisure and touring caravans requiring a lightweight 12V house battery\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\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Victron Lithium SuperPack 12.8V\/20Ah (M5) battery\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThe built-in BMS handles cell-level protection, but correct system design is still required. Ensure the charger used is compatible with LiFePO4 voltage profiles (absorption voltage typically 14.2V, float 13.5V). Do not connect this battery in series or parallel with other units. For marine installations, secure the battery against movement and protect terminals from moisture ingress. Installation should be carried out by a qualified electrician or marine engineer familiar with lithium battery systems.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59866753925454,"sku":"BAT512020705","price":138.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_BAT512020705_-_Lithium_SuperPack_12_8V-20Ah_M5.webp?v=1781200378","url":"https:\/\/voltaconsolar.com\/products\/victron-lithium-superpack-12v-20ah-m5","provider":"VoltaconSolar","version":"1.0","type":"link"}
