![]() ![]() You should consider using strips of Samsung Gen3 F-Series or Bridgelux EB Series Gen2. You would connect in parallel multiple sets of 10 (or 11) of the D batteries wired in series. You need a 12V inverter with a 120V output. Available in a wide range of sizes and performance options.Economically priced NiCd is the lowest in terms of cost per cycle.Simple storage and transportation not subject to regulatory control. ![]() Long shelf life can be stored in a discharged state, needs priming before use.Good load performance forgiving if abused.Only battery that can be ultra-fast charged with little stress.Rugged, high cycle count with proper maintenance.A lead acid battery that can handle daily deep discharge (e.g. Typically this would be powered by a lead acid battery with an inverter.Ī NiMH battery is much more reliable and can be cycled more times and handles a deep discharge much better than lead acid. Your idea is not as insane as these guys make it out to be. If you use rechargeable cells, how do you plan to recharge and replace 80 cells each day? (In a school locker? Really? With an orange tree in there too?)Ĭonsider how often you will have to replace the batteries. I posted this with the intent to convince you how impractical your plan is.Ĭonsider how you would connect 80 D cells together.Ĭonsider how much volume you would need to contain that many batteries. After just a couple of days that will be cheaper than the D Cells. You would be better off purchasing a solar panel with a charger and battery. One stack of 80 will run you to about $60. Probably better to put a second stack of 80 in parallel. You have 150W at 120V, so that draws about 1.25A.Ĭapacity is measured in watt hours (Wh) or ampere hours (Ah.)Īn alkaline D Cell has a capacity of around 12Ah so if you are lucky you only need one stack of 80 cells. A D cell is nominally 1.5V, so you would need 80 D Cells in series to reach 120V. ![]()
