Battery discharge device

[Thanev]

Is anyone aware of the pinout on the Mini battery?
I would like to develop a discharge harness using a small automotive light bulb and a battery level alarm.
I have built one for my rc aircraft batteries and it works great.

i have one that i use for my three cell batts for my older drones and the batteries for my MPP i was thinking of getting and old USB cable and soldering it to the input and then i can put one battery at a time in the hub and discharge it using the bulb as i do with the others you should be able to get the info you need off the net as thats what i will have to do

I can’t speak for the mini as I don’t own one, but the pin out for the Mavic 1 is on the backside of the charger and car charger. See photo.
You could turn on the battery and check pins with a multimeter.

If only I had a multi meter....

How do you live without a multimeter?

I sacrificed one of the battery plugs from my Yx charger to connect to my discharger. I could have just made an adapter but didn't have the connectors.

Could you be so kind as to provide a pin out diagram to answer the OP’s question?

Nice job! I think I see a market for these.

B & H has them for the Mavic Pro. Give them a little time....

Check the battery mod thread.

Anybody knows the + and - pins from bird battery connection? I’m gonna make a clip for test with dual battery. Do you think MM can fly with extra 100gr?

The connector pinout is

Thanks. That makes sense. Just scaled down version of Mavic Pro connector.
Now we know.

Good setup. I have a similar one for my Mavic Air. The discharger is a handy tool and will drain battery to storage level fast and consistently. ISDT Discharger . Not ready to sacrifice a Yx charger cable, yet, as I am looking for a MM battery cable that I can solder to the XT60 plug for the discharger. Enjoy your flying.
