Battery mod thread

How have you all changed to non-DJI battery?

At the end of page 4 from this trhead, you'll find some instructions. I don't know anyone has tested, but you could be the first.

Sanyo 20700 does not fit 1mm((

Is there any extra space in battery compartment that we can strip off some of the plastic to fit in 20700?

Yes, it possible

Could i buy new battery and mod that one?

I've bought 7 new batteries and they all come updated so I would not recommend doing this..

someone tells maybe the secret is not to fly before swap the cells. If you fly, bms switchs off if you swap It’s only a theory.

Doesn't work. I didn't fly before the swap. I bought the batteries to do the swap

Thanks! mystery continues .....

It is strictly getting ones that haven't been updated... And only way to know this is to turn mini on with battery and see if it says update battery on the dji splash screen

 

[Liamjason123]

Is it not possible atall even to add a battery without tampering with the updated cells just solder two wires and add battery that way? like i think ive seen on here?

 

[Liamjason123]

Also had anyone tried rolling back to 0.200 firmwere and see if batterys can be done that way maybe removes battery update aswell?

Yes of course you can. But the best battery gain as of right now is 2 21700 cells with a bms. You can add a battery pack with stock battery, it will get you about 35 min of flight time.

¿También alguien intentó retroceder a 0.200 firmas y ver si las baterías se pueden hacer de esa manera, tal vez también elimine la actualización de la batería?
[/CITAR]I’ve tried downgrade Drone’s firmware to 200, but batterys don’t downgrade.

With Adding 2 x stock Samsung cells at cell level in parallel can we get 35 min ? I’ve tried with 2 x Sony 3000 20A in parallel solder at stock battery’s bornes and only gotten 26 min.

Justin so i should be able to do that even tho my battery has been updated solder two cells on and there be no issue? Thanks again just want to make sure before i attempt

 

[Tesla Hertz]

all this is so risky, i gave up.

 

[Tesla Hertz]

if you do anything just do what justin did, dont mess with the bms, just add batteries, do not try and replace them, then you should be safe.

Yes this was my first way of doing it.

You have to watch your actual voltage of cells. The mini will sometimes try a forced landing when you still have around 3.5volts per cell... You can stay in the air until it force lands you completely at 3.17volts.

By switching to non dji mode this gets eliminated and you can stay in the air until 2.5volts. However with the added weight the mini has a hard time even hovering after 3volts per cell.
