родной блок питания не подойдёт для одновременной зарядки?me_8cac6Swo9D wrote: ↑Mon Mar 01, 2021 11:52 amEasy ... batteries are connected serials, charging will be in 'hubsan's style' serials too. When first is charged, next starts charging ... etc ...
The current to one is approximately cca 2A. Do you think that the source and also its thin wires could handle 3 batteries at once?
Charging in series makes sense when you connect everything at once and everything is charged without waiting for the next one to connect.
Better is use any 12V/3-6A power sources (f.eg. STB has same 2,5(or 2.1mm?)/5,5mm and voltage power sources) for each standallone battery, if you have not time.
I think, it is feature ... charge first, then charge second, then third... I haven't read anywhere that it charges all at the same time.
Better to charge like this than wait for charge first and then give charge the second etc.
