The nominal voltage of an LFP cell is 3.2V (Lead-Acid: 2V\/cell). A 12.8V LFP battery therefore consists of 4 cells connected in series and a 25.6V battery consists of 8 cells connected in series.\u003cbr\u003e \u003cbr\u003e \u003cb\u003eRobust\u003c\/b\u003e\u003cbr\u003e A lead-acid battery will fail prematurely due to sulfation in the following cases:\u003c\/p\u003e \u003cul\u003e \u003cli\u003eIf it is operated for a long time in an insufficiently charged state (i.e., if the battery is rarely or never fully charged).\u003c\/li\u003e \u003cli\u003eIf it is left in a partially charged or, even worse, completely discharged state (yacht or motorhome during winter).\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eAn LFP battery does not need to be fully charged. The operating life even slightly increases if the battery is only partially charged instead of fully charged. This is a significant advantage of LFP batteries compared to lead-acid batteries.\u003cbr\u003e Further advantages include a wide operating temperature range, excellent cycling, low internal resistance, and high efficiency (see below).\u003cbr\u003e The LFP battery is therefore the best choice for demanding use.\u003cbr\u003e \u003cbr\u003e \u003cb\u003eEfficient\u003c\/b\u003e\u003cbr\u003e In many applications (especially off-grid solar and\/or wind power systems), energy efficiency can be crucial.\u003cbr\u003e The energy efficiency of a charging cycle (discharging from 100% to 0% and recharging to 100%) of an average lead-acid battery is approximately 80%. The energy efficiency of an LFP battery's charging cycle, on the other hand, is 92%.\u003cbr\u003e The charging process of a lead-acid battery becomes particularly inefficient once the 80% state of charge mark has been reached. This leads to energy efficiencies of only 50%.\u003cbr\u003e In solar systems, this value is even lower, as energy reserves for several days are needed there (the battery operates at a state of charge between 70% and 100%).\u003cbr\u003e An LFP battery, on the other hand, still achieves an energy efficiency of 90%, even when it is in a shallow discharge state.\u003cbr\u003e \u003cbr\u003e \u003cb\u003eSize and Weight\u003c\/b\u003e\u003cbr\u003e Space savings of up to 70% Weight savings of up to 70%\u003cbr\u003e \u003cbr\u003e \u003cb\u003eExpensive?\u003c\/b\u003e\u003cbr\u003e LFP batteries are expensive compared to lead-acid batteries. However, the higher acquisition costs will more than pay off in demanding applications due to the longer operating life, high reliability, and excellent energy efficiency.\u003cbr\u003e \u003cbr\u003e \u003cb\u003eBluetooth\u003c\/b\u003e\u003cbr\u003e Cell voltages, temperature, and alarm status can be monitored via Bluetooth. This is very useful for detecting a (potential) problem such as cell imbalance.\u003cbr\u003e \u003cbr\u003e \u003cb\u003eBattery Management System (BMS)\u003c\/b\u003e\u003cbr\u003e The BMS can be connected to the BTVs and its main functions include:\u003c\/p\u003e \u003cul\u003e \u003cli\u003eInterrupting or shutting off the load if the voltage of a battery cell drops below 2.5 V.\u003c\/li\u003e \u003cli\u003eStopping the charging process if the voltage of a battery cell rises above 4.2 V.\u003c\/li\u003e \u003cli\u003eShutting down the system if the cell temperature exceeds 50°C.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eVictron LFP batteries have integrated cell balancing and cell monitoring functions. Up to ten batteries can be connected in parallel and up to four batteries in series, allowing for a 48 V battery bank of up to 3000 Ah. An example wiring diagram can be found in the product images. The cell balancing\/monitoring cables can be daisy-chained and must be connected to a Battery Management System (BMS).\u003cbr\u003e \u003cbr\u003e \u003cb\u003eTechnical data:\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003e\u003cimg alt='\"Technical' data smart batteries victron class='\"img-responsive\"' src='\"https:\/\/alt.solar-kontor.de\/mediafiles\/\/Bilder\/technischeDaten\/Victron\/Batterie\/technische_daten_smart_batterien_victron_lithium.JPG\"' style='\"width:'\u003e\u003c\/p\u003e\u003ch4\u003eDocuments \u0026amp; Downloads\u003c\/h4\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/media.wattstunde.de\/mediafiles\/PDF\/Elektronik\/Victron\/Batterien\/Datasheet-12,8-\u0026amp;-25,6-Volt-lithium-iron-phosphate-batteries-Smart-DE.pdf\" target=\"_blank\"\u003eDatasheet\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":57444350263678,"sku":"WS300-2012","price":1040.83,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0906\/7557\/7214\/files\/victron-smart-lithium-100-ah-batterie-lifepo4-128v.jpg?v=1779291893","url":"https:\/\/www.offroad-fittery.de\/en\/products\/victron-smart-lithium-100-ah-batterie-lifepo4-12-8v","provider":"Offroad-Fittery","version":"1.0","type":"link"}
