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\n\u003cbr\u003e\n \u003cb\u003eRobust\u003c\/b\u003e\u003cbr\u003e\n A lead-acid battery will fail prematurely due to sulfation in the following cases:\u003c\/p\u003e\n\n\n\u003cul\u003e\n\n\u003cli\u003e If 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\n\n\u003cli\u003e If it is left in a partially charged or, even worse, completely discharged state (yacht or motorhome during the winter).\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\n \u003cp\u003eAn LFP battery does not need to be fully charged. Its service life even increases slightly if it is only partially charged instead of fully charged. This is a significant advantage of LFP batteries compared to lead-acid batteries.\u003cbr\u003e\n Further advantages include a wide operating temperature range, excellent cycleability, low internal resistance and high efficiency (see below).\u003cbr\u003e\n The LFP battery is therefore the best choice for demanding use.\u003cbr\u003e\n\u003cbr\u003e\n \u003cb\u003eEfficient\u003c\/b\u003e\u003cbr\u003e\n In numerous applications (especially in off-grid solar and\/or wind power plants), the energy efficiency can be of crucial importance.\u003cbr\u003e\n 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%. In contrast, the energy efficiency of a charging cycle of an LFP battery is 92%.\u003cbr\u003e \nThe charging process of a lead-acid battery becomes particularly inefficient once the 80% charge level is reached. This results in energy utilization rates of only 50%.\u003cbr\u003e\n For solar power systems, this value is even lower, as energy reserves are needed for several days (the battery operates at a charge level between 70% and 100%).\u003cbr\u003e\n In contrast, an LFP battery still achieves an energy efficiency of 90%, even when it is in a shallow state of discharge.\u003cbr\u003e\n\u003cbr\u003e\n \u003cb\u003esize and weight\u003c\/b\u003e\u003cbr\u003e\n Space savings of up to 70%, weight savings of up to 70%\u003cbr\u003e\n\u003cbr\u003e\n \u003cb\u003eExpensive?\u003c\/b\u003e\u003cbr\u003e\n LFP batteries are expensive compared to lead-acid batteries. However, the higher initial costs will more than pay for themselves in demanding applications due to their longer service life, high reliability, and excellent energy efficiency.\u003cbr\u003e\n\u003cbr\u003e\n \u003cb\u003eBluetooth\u003c\/b\u003e\u003cbr\u003e \nCell voltages, temperature, and alarm status can be monitored via Bluetooth.

Up to ten batteries can be connected in parallel and up to four in series, allowing you to assemble a 48V battery bank with a capacity of up to 3000Ah. An example connection can be found in the product images. The cables for the cell balancing\/monitoring function can be daisy-chained and must be connected to a battery management system (BMS).\u003cbr\u003e\n\u003cbr\u003e\n \u003cb\u003eTechnical data:\u003c\/b\u003e \u003c\/p\u003e\n\n\n\u003cp\u003e\u003cimg alt=\"Technical specifications 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: 70%;\"\u003e\u003c\/p\u003e\n\n","brand":"Victron Energy","offers":[{"title":"Incl. 19% VAT","offer_id":56299655758199,"sku":"300-2012","price":737.38,"currency_code":"EUR","in_stock":true},{"title":"Including 0% VAT according to Section 12 Paragraph 3 UStG.","offer_id":56299655790967,"sku":"300-2012","price":619.65,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/6770\/8791\/files\/lithium-128v-100ahjpg-327892.jpg?v=1764770425","url":"https:\/\/solorkontor.shop\/en\/products\/victron-smart-lithium-100-ah-batterie-lifepo4-12-8v","provider":"Solarkontor","version":"1.0","type":"link"}
