Torqeedo Power 26-77More power, lighter weight – Torqeedolithium-manganese batteries for the highestdemandsLithium batteries represent the leading battery technology onthe market today. The advantages they offer over conventionalbatteries are dramatic: They have a much higher energydensity, they easily deliver high current and they also featureoutstanding cyclic stability and therefore a long service life.Lithium batteries provide various options for use on boats.On the one hand, you can save around 70% battery weight.Alternatively you can increase the capacity of your batterybank substantially and drive more powerful electric outboardsor simply have more energy at your disposal on theship. While batteries from the Torqeedo Power series reflectlatest battery technology, they’ve also been proven on themarket for several years.1132.0 kWh (25.9 V, 77 Ah)241.9 lbs2-yearlimitedwarranty1 Solid copper connections with M19threads for optimum electric conduction.2 Two plus and two minus poles forconveniently connecting severalbatteries.

For safetyreasons, they are equipped with standard 120 A internal fuses. The maximum power delivery per battery is approximately 3.1 kW. Higher power deliveriesrequire either more batteries in series or Torqeedo must modify the fuses (then up to 10 kW can be delivered per battery). Connecting batteries (paralleland serial): Up to 40 batteries per bank. Installation of banks consisting of 2 batteries or more only after instruction by Torqeedo. Serial connections of morethan 2 batteries may be performed only by personnel trained and authorized explicitly by Torqeedo.

Safety is a the primary design principle forTorqeedo lithium-batteries. Three aspects areimportant:Chemical battery composition: Batteries arefrequently described non-specifically as lithium-ion batteries.This is a collective term that groups together various typesof battery chemistries. Some of these, e.g. lithium-cobalt orlithium-cobalt mixed with nickel, fail in appropriate safety testsand are fire and explosion hazards. This is why they shouldnot be used in larger batteries. Other battery compositionssuch as lithium-iron-phosphate or the lithium-manganese typeused by Torqeedo are intrinsically safe, even in a case whenthe safety electronics fail, or if the batteries are mechanicallydamaged.Battery casing: If there is an internal short-circuit, explosivegases can develop inside a lithium battery. For lithiumbatteries in polymer packaging, this can result in pressurebeing build up, which can ultimately burst the casing.The explosive gas then released is a serious hazard. For thisreason, Torqeedo does not employ polymer packaging butmetal safety cells, which feature a safety vent. If internalpressure builds up, the metal cylinder expands at a pre-definedpoint and mechanically separates the cathode from theanode. This deactivates the battery, explosive gas will notbe released.Fuses: Unlike lead batteries, lithium batteries can deliververy high currents without problems. In case of a short-circuit,this is an undesirable side effect. Therefore, Torqeedobatteries have internal 120 A fuses so that any incorrectinstallation without external fuses will not cause severeunwanted side effects.Energy densities: Comparison of lead-gel batteries andlithium-manganese batteries of the same weight (42 lbs)Available capacityin WhLithium battery with longer servicelife due to better cycle stabilityCapacity in % ofrated capacity2,0001,500Power 26-77(Lithium manganese)Energy shownalmost fully availablefor utilisation806050% depth of dischargeLithium-manganese battery80% depth of discharge50% depth of dischargeQuality lead-gel battery1,000Weight saving withlithium batteries >70%4080% depth of discharge500Quality gel battery with the same weight(12 V, 55 Ah).
