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\nA lead-acid battery will prematurely fail due to sulfation in the following cases:\u003c\/p\u003e\n\n\u003cul\u003e\n\t\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\n\t\u003cli\u003eIf it is left in a partially charged or, even worse, completely discharged state (yacht or RV during winter).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eAn LFP battery does not need to be fully charged. Its 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\nFurther advantages include the wide operating temperature range, excellent cycling, low internal resistance, and high efficiency (see below).\u003cbr\u003e\nThe LFP battery is therefore the best choice for demanding use.\u003cbr\u003e\n\u003cbr\u003e\n\u003cb\u003eEfficient\u003c\/b\u003e\u003cbr\u003e\nIn many applications (especially off-grid solar and\/or wind power systems), energy efficiency can be crucial.\u003cbr\u003e\nThe energy efficiency of a charge cycle (discharging from 100% to 0% and recharging to 100%) of an average lead-acid battery is approximately 80%. The energy efficiency of a charge cycle of an LFP battery, on the other hand, is 92%.\u003cbr\u003e\nThe charging process of a lead-acid battery becomes particularly inefficient when the 80% state of charge mark is reached. This results in energy efficiencies of only 50%.\u003cbr\u003e\nIn solar systems, this value is even lower, as energy reserves for several days are needed there (the battery operates in a state of charge between 70% and 100%).\u003cbr\u003e\nAn LFP battery, on the other hand, still achieves an energy efficiency of 90%, even when it is in a shallow discharge state.\u003cbr\u003e\n\u003cbr\u003e\n\u003cb\u003eSize and Weight\u003c\/b\u003e\u003cbr\u003e\nSpace savings of up to 70% Weight savings of up to 70%\u003cbr\u003e\n\u003cbr\u003e\n\u003cb\u003eExpensive?\u003c\/b\u003e\u003cbr\u003e\nLFP batteries are expensive compared to lead-acid batteries. However, the higher acquisition costs will more than pay off in demanding applications due to their longer operating 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. This is very useful for detecting a (possible) problem such as cell imbalance.\u003cbr\u003e\n\u003cbr\u003e\n\u003cb\u003eBattery Management System (BMS)\u003c\/b\u003e\u003cbr\u003e\nThe BMS can be connected to the BTVs, and its main functions include:\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003eInterrupting or shutting down the load when the voltage of a battery cell drops below 2.5V.\u003c\/li\u003e\n\t\u003cli\u003eStopping the charging process when the voltage of a battery cell rises above 4.2V.\u003c\/li\u003e\n\t\u003cli\u003eShutting down the system if the cell temperature exceeds 50°C.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\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 the assembly of a 48V battery bank with up to 3000Ah. An exemplary 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).\u003c\/p\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003chr\u003e\n\u003cp\u003e \u003c\/p\u003e\n\n\u003ctable style=\"background: rgb(223, 224, 223);\" width=\"100%\"\u003e\n\t\u003ctbody\u003e\n\t\t\u003ctr style=\"height: 40px;\"\u003e\n\t\t\t\u003ctd style=\"background: rgb(251, 251, 251);\"\u003e\u003cspan style=\"font-size: 24px;\"\u003e\u003cstrong\u003eTechnical Data\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\t\t\t\u003ctd style=\"background: rgb(251, 251, 251);\"\u003e\u003cspan style=\"font-size: 24px;\"\u003e\u003cstrong\u003eVictron Smart Lithium 12.8V 200Ah\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\t\t\u003c\/tr\u003e\n\t\t\u003ctr style=\"height: 18px;\"\u003e\n\t\t\t\u003ctd style=\"height: 18px;\"\u003eNominal Voltage\u003c\/td\u003e\n\t\t\t\u003ctd style=\"height: 18px;\"\u003e12.8V\u003c\/td\u003e\n\t\t\u003c\/tr\u003e\n\t\t\u003ctr\u003e\n\t\t\t\u003ctd style=\"background: rgb(251, 251, 251);\"\u003eNominal Capacity\u003c\/td\u003e\n\t\t\t\u003ctd style=\"background: rgb(251, 251, 251);\"\u003e200Ah\u003c\/td\u003e\n\t\t\u003c\/tr\u003e\n\t\t\u003ctr\u003e\n\t\t\t\u003ctd style=\"height: 18px;\"\u003eMax.
