Hot wire wire stripper. Runs off 5 volts and uses about 2 amps. Makes a good bit of smoke!
In diesem Video wird davor der Energieinhalt des Akkupacks von 12,5Wh bestimmt. Anschließend wird es mit einem 40 Watt Ventilator belastet und die Zeit gemessen. 7 Zellen mit jeweils 500mAh halten im Test circa 15min bei 40 Watt Leistung durch, was einen Energieinhalt von 10Wh ergibt.
Dabei handelt es sich um schlechte Zellen mit niedriger Kapazität.
Die für meinen späteren Hausspeicher selektierten Zellen haben gut die 4-fache Kapazität, also um die 2000mAh.
