Hello! So the weather probably here in Czech Republic will be really bad for this weekend and that brings me to this question. If I won`t use the batteries for a few days at what percentage should i store them? I heared that I should let it between 50% to 60% it that true? That means the 3rd light blinking. Or what should I do? A what percentage should I store them?

Hi there, thank you for reaching out. With regards to that. Yes, 60%-50% would be fine. and never stored it when fully charge. And if ever you will store it for a longer time, we would recommend checking it at least one times a week just to make sure there will be no problem. Best Regards!

Storing for a few months - I would give the battery storage some thought.  

A few weeks - maybe I'd think about it some - depending on the present charge of a particular battery.  

I would not in any way be concerned about "a few days."  

Good luck.  

Just let the Auto Discharge system do its job. The battery will self discharge to storage level reducing possibility of damage due to leaving fully charged.

Just remember to charge up regardless of LED lights indication before flight later.
