Very nice, but I have one remark to make. You must take into account the internal resistance of the battery which for this kind is around 1.5ohms. Then following the ohms law you wont get more than 1A even at max charge. That is a big restrain for the blocking oscillator and if you try and add 1.5ohms in series with the supply you'll see that it wont work at heavier loads. Also you'll need heavy filtering at a 6hz frequency.

Veľmi pekné, ale mám jednu poznámku, aby sa. Musíte vziať do úvahy vnútorný odpor batérie, ktorá pre tento druh je okolo 1.5ohms. Potom sa po práve ohmov ste zvyknutý mať viac ako 1A aj pri max nabití. To je veľký obmedzí na blokovacie oscilátor, a ak sa pokúsite a pridať 1.5ohms v sérii s ponukou, budete vidieť, že je zvyknutý pracovať na väčšie zaťaženie. Tiež budete potrebovať ťažký filtrovanie pri 6 Hz frekvencia

It's just bugger's comment, very maturely regurgitated back at him in, whatever language that is..
