About this model

So you can take advantage of an AA size Li-ion battery pack of 2 AA sized batteries. Originally powered by a 3V device (Li-ion battery 3.7V), the voltage must be reduced by 2 diodes. Use any (minimum 1A) diode (eg 1N4001). Így lehet használni a Li-ion akkukat (melyek 3.7V-osak) egy olyan eszközben, ahol 2db AA méretű elem/akku használatos. A dióda a feles feszültség elejtésére kell. Használhatsz bármely sima min. 1A-es (vagy több) diódát. Úgy forraszd be, hogy a diódák a negatívtól a pozitív felé vezessenek.
