Product review & video
Let's just say you just created a homemade lithium-ion battery bank And if you have no idea how to do this then check out one of my previous videos Anyway, my pack got 4 cells in series with 2 cells in parallel each Which means it covers a voltage range of 16.8 to 12 volts outputs up to 40 amps continuously Features a capacity of 5 amp-hours and thus a nominal energy of 72 watt-hours That means that after adding wires to the pack and adjusting its output voltage to constant 12V with a suitable converter It is perfect for powering 12 volt devices But such a naked battery pack is not 100% safe to work with For example, if the battery pack got discharged I can charge it up with an appropriate constant-current constant-voltage method But during that process I noticed that not all cells feature the exact same voltage The reason is that not every cell is chemically identical and thus they all
