    Calculating Three-Phase Power 110V

    P = V X PF X A. If not sure of the power factor (PF) use .7 for capacitive loads or .8 for inductive loads.

    Lithium Battery. Increasing my voltage.

    The battery will continue to decrease voltage under any load down to a voltage level of the battery open circuit fully discharged level. For a safer battery consider switching to the Lithium IRON LiFePO4. Commonly called LFP. It has a much flatter discharge curve than other Lithium ION based...

    Battery Life Decreasing as Current is Increasing

    I have built battery chargers powered from a typical USB. I find that the output voltage of the USB is not stable enough to properly charge a battery. The way I solved this was to build a voltage regulator that can output 500mA. Use a regulate voltage that matches the safe charge voltage of the...
