AdvantagesofLithiumBatteriesExtendedLifespanLaboratory tests show that you can expect to see about 2000 to 5000 cycles from a well-maintainedLiFePO4 battery bank. These results also show that a lithiumbatterywill delivermore than 75%of itscapacityafter2000cycles.Incontrast,eventhebestdeepcycleAGMbatteriesaretypicallyonlygoodfor500-1000cycles. Considerthe longer lifespanof lithiumandreplacementcostsofAGMbatterieswhenevaluatingthepricedifferences.MoreUsableCapacityUnlike with lead-acid batteries that are rarely discharged beyond 50%, Lithium batteries can regularlydischarge85%ormoreoftheirratedcapacity.Takeforexamplea100amphourbattery–ifitwaslead-acid,youwouldhaveaccesstoonly30to50amphoursofcharge,butwithlithiumyoucoulduse85amphoursormore. Whenevaluatingcost,considerthatthere isnotan“applestoapples”amphourratingcomparisonbetweenthebatterytypes.YougetabouttwiceasmuchchargeinasimilarlyratedlithiumbatterybankasyouwouldwithAGMbatteries.NoVoltageSagAsthechargelevelonalead-acidbatterydecreasessodoesthevoltage.Thismeansthatyourlightswillget dim and your appliances start to run rougher. The discharge curve of lithiumbatteries (especiallywhencomparedto lead-acid) isessentially flat,meaningthata lithiumbatteryat20%willbeprovidingnearly the same output voltage as it would at 80%. On the flip side, once lithium batteries are fullydischarged,theirvoltagedropsoffrapidly,anditisthegoaloftheintegratedBMS(BatteryManagementSystem)toprotectthebatteriesandpreventthisfromeverhappening.Completelydischargingalithiumbattery bank, even just once, can permanently ruin it. Keep in mind that any battery monitor orgenerator auto-start dependent upon detecting sagging voltage levelswill likely notwork on a lithiumbank. Ashuntbased,calibratedmonitoringsystemwillbethemosteffectivewaytodetectthechargelevelofalithiumbatterybank.HighCurrentOutputAnotherhugeadvantageoflithiumbatteriesisthatPeukert’slossesareessentiallynon-existent,meaningthatlithiumbatteriescandelivertheirfullratedcapacity,evenathighcurrents.Withlead-acidbatteriesyoucanseeasmuchasa40%lossofcapacityathighloads.ThismeansthatLithiumbatterybanksaremuchbetteratpoweringhighcurrentloadslikeanairconditioner,amicrowaveoraninductioncooktop.Fast&SimpleChargingUnlikeleadacidbatteries,lithiumbatterieshavenoneedforanabsorptionphasetochargethefinal20%,whichmeans that lithiumbatteriescanquicklybecharged to full capacity. If yourchargercanprovideenoughamps,lithiumbatteriescanbechargedinaslittleas30minutes,whichmeanslesstimewithyourgenerator.Additionally,withlithiumbatteriesyoudon’tevenhavetofullytopoffthebatterybankwitheach charging cycle. You will never have to deal with sulfation or a manual equalization cycle. Thissimplicity gives you freedom to tap into energy sourceswherever you can find themwithoutworryingaboutneedingtodoaregularfullcharge.Withlithiumbatteriesyoudon’thavetoworryaboutleavingyour battery bank perpetually undercharged.

MinimalMaintenanceCompared to lead-acidbatteries, lithiumbatteries aremostlymaintenance free. TheBMSdoesall thethinking for you, and automatically performs a “balancing” process (similar to equalization) that usesresistorstobleedoffexcesscharge,andensurethatallthecellsinthebatterybankareequallycharged.Additionally,theBMSalongwithhighcurrentcircuitry,preventsexcessivedischarges.Allyouhavetodoissimplychargeyourbattery,orbetteryet,letyoursolarpanelschargeyourbattery.EfficientCharge/DischargeLithium batteries aremuchmore efficient than lead-acid batteries at storing power. Lithium batteriescharge at nearly 100% efficiency, compared to the 85% efficiency ofmost lead-acid batteries. This isespecially importantwhenchargingviasolar,whenyouaretryingtosqueezeasmuchefficiencyoutofeveryhourofsunlightaspossible.Intheory,withlithium,nearlyeverysecondofsunshineyou’reabletocollectresultsinpowerstoredinyourbatterybank.TemperatureResistanceLead-acidand lithiumbatterieshave reducedcapacities in coldenvironments,but lithiumbatteriesaremuchmore efficient at low temperatures. At -20°C, a Lithium battery that delivers a 1C current (onetimesitscapacity),candelivermorethan80%ofitsenergy.Incontrast,theAGMbatterywillonlybeableto deliver 30% of its capacity. For harsh environments (hot and cold), Lithium is the better batterytechnology.EasyPlacementLithiumbatteriesdonot gas like lead-acidbatteries, anddonotneed tobe stored in a ventedbatterycompartment. They can also easily be assembled into a variety of shapes, which is an importantadvantageifyouaretryingtosqueezeasmuchpowerstorageaspossibleintoasmallcompartment.Thisisalsousefulifyouhaveanexistingbatterybaythatis limitedinsize,butyouwantmorecapacitythanlead-acidbatteriesareabletoprovide.WeightReductionLithiumbatteriesareafractionoftheweightofAGMbatteries.Yourvehiclewillhandlebetterandgetmoremilespergallon.TaxIncentivesConsider the implicationsof the30%federal taxrebate,whichwillbeavailable through2016. Inmanycases,thisrebatecancoverthecostofyourbatterybankupgrade.SafetyAsyoumightrecallfromnewsstoriesafewyearsago,lithiumionbatterieshaveearnedareputationforcatchingfireinaverydramaticfashion,butthatwastheoldtechnology.OneoftheearlycommonlyusedlithiumionbatteryformulationshadbeenLithium-Cobalt-Oxide(LiCoO2).Thisbatterychemistryisproneto thermal runaway if the battery is accidentally overcharged. Overcharging could lead to the batterysettingitselfonfire,andalithiumfireburnshotandfast.Thisisoneofthereasonsthatupuntilrecently,lithiumwas rarely used to create large battery banks. But, in 1996 a new formula formixing lithiumbatteries was developed - Lithium Iron Phosphate. Known as LiFePO4 or LFP, these batteries have aslightly lowerenergydensity,butare intrinsicallynon-combustible, and thus, vastly safer than Lithium-Cobalt-Oxide.AMSolarlithiumbatterybanksusethenewLiFePO4technology.

They connect between thepositiveandnegativeterminalsofeachcellgroupandmonitorthevoltageofthatcellgroup.Whenthevoltage of one cell group gets too high or too low, the balancing boards signal the BMS Processor byinterruptingthecurrentflowontheyellowcellloopcable.The BMS Processor is housed in the black box located on the BMS board. When the BMS processordetectsanopencircuitinthecellloopitsignalsthesolenoidtoopen.Whenthesolenoidisopened,theinverter/chargerandallDCloadsorchargingsourcesaredisconnectedfromthebatterybank,exceptthesolarchargecontroller.The solar charge controller has programmed protections that keep it from over charging your batterybank. If the solenoid was opened because of excessive discharge, the solar charge controller willeventuallyremedythesituationbychargingthebatterybankbackuptoahealthylevel.Thesolenoidwillremainopenuntilthevoltagelevelsofthelithiumcellgroupsareathealthylevelsandthemomentaryswitchispressed.The purpose of the momentary switch is to hold the solenoid ‘closed’ for a period of two minutes,allowingemergencyaccesstothebatterysystem,andtoresettheBMSCPUboard.Ifthevoltagelevelsofthe lithiumcell groups are at healthy levels, the solenoidwill continue tohold in the ‘closed’ position,thereby resuming normal operation. If not, the solenoid will ‘open’ rendering the battery systeminoperable.CellBalancingThisautomaticprocessisconceptuallyverysimilartotheequalizationprocessoffloodedbatteries.Thatbeing said, a lithium battery should never be equalized.
