I put it on charge 1A / h with a power supply. The drone cycles through the lights for a few seconds and then the lights go out. Well, I think, okay, apparently he is so charged. And no! This is a half-dead charger! Have a high-quality 2A / h charge! Should I take a combo? For the price of a combo, itβs more profitable: separately purchased batteries are two and charging will come out more expensive. But personally, I want to buy only one battery and that's enough. For that it will come out economically. Thank you onlinetrade ru for the promotion: price + sd card as a gift
