Mavic air battery charger

[Geani66]

I bought a charger from Amazon in order to be able to keep my batteries safe but this thing it showing the levels in volts not percent……everywhere I checked the advice is to keep the levels to 40,50 percent for long term storage
How do I interpret this?
Volts to percent?
i have one for the mini 2 but it’s in percentage,volts and it’s great.
This is the charger

Thank you

I don't own a Mavic - but do the batteries themselves have leds that tell you charge level as they charge?

I was going to toss is some generic data - but batteries are too expensive to gamble with.

You are right. This great charger (I used it myself before I switched to the MA2) shows the level in volts. Never mind, One of the best functions is the discharge possibility. That way the batteries, full or empty doesn't matter, will go to 50% for perfect storage for a longer time.

Thank you for your answer but this one it doesn’t discharge…..only charges.

Charge them with the battery lights as reference. Two steady and the third flashing will give you between 50 and 63%

Yes…thank you.
So this charger is useless….I can do this with the original charger and keep 50$ in my pocket.
I found something interesting on the internet

Mini 2 battery is 3S….I guess

I see. I had another model from Hanatora with a knob to discharge, but that model cost a little more.

Generic battery discharge curves from the web can be misleading. Most Lithium batteries you buy have controllers built in and the terminal voltage is probably not the true cell voltage; especially when charging or discharging. The internal electronics do thermal, current and voltage limiting, even charge distribution in some batteries, and DJI isn't forthcoming on detailed technical facts, so my guess is third parties are reverse engineering and also guessing.
