Mavic Pro Battery Mod

I have a question does it have to be 3 cell battery or can we use a 4 cell battery with the clip

3 cell only. The voltage is too high on the 4 cell batteries.

Two of us so far has had compass errors with the Titan battery.

I think I'm going to buy me a 3D printer. Anyone know what a good starter one would be?

Ed209,

Have you tried testing the Titan battery on something else? Maybe a random RC motor with low current (under 10A) draw. Then test it with the other 1500mAh battery you have. If the results are similar to what you got with the Mavic, then perhaps the cells used in your Titan were lower quality.

I'm wondering if the people at Titan went with an alternative supplier for their batteries in order to meet the demand after the spike in interest.

By testing TWO different Titan batteries and then following that up with a test of batteries that I've run before I'm pretty sure I eliminated any bad cells. I cant speak for Titans supply and manufacturing but I jumped and ordered the Titans the same day that DJ posted up just because I needed to see for myself. Knowing full well that these were most likely not going to perform. I flew despite compass errors and if they performed, I would fly them for distance despite the compass errors. I think I was ahead of the "rush" for all the people who ordered. I don't really think it was that many in actuality.

Hey DJ! You running android or ios? Get HDsync and create an account at airdatauav.com. Sync your logs and share the data for your 52min flight. We would all love to take a look.

Btw I don't think 52min is possible just by plugging a Titan into a Mavic. As mentioned in the other thread, you'll need an Arduino nano to act as man in the middle to trick the Mavic BMS so that voltage cutoff is avoided or adjusted. I'm not sure if modifying flight parameters [emoji56] would be enough. Otherwise, you're leaving so much power "on the table" when the Mavic main battery is reporting that it's empty.

So I did a hover test today with 2 Zippy 1300mah batteries. I started with 96% on the mavic battery and and I hovered for 24:31 as you can see in the screenshot. When I uploaded the flight log to "Airdata UAV" it shows a much different story (see bottom pic) where it states that the flight was only 10:31 and that I landed with 62% battery left when I really landed with 13% battery and the flight time was 24:31.
Was the flight log just incomplete or is something else going on? Again this was only a hover test. I only took it up to around 3 feet.

Ok boys I finally figured out how to get the battery on here and hopefully it won't interfere with the compass or gps unit. I'll give it a run in the morning weather permitting. Keep your fingers crossed.

Original Prusa mk 2 s....i3.. don't have one but good reviews...would like one....

Funny I got same thing yesterday....same flight in 3 files...strange ...short disconnections perhaps...

Yeah that would have been real nice to have. No weight at all!

Thanks I'll check it out.

They say that one is back logged 4 weeks due to high demand. I like the price too.

People here panic if you dont check in on an hourly basis.
What was the voltage of the titan after the epic flight? What fw version are you on?

 

[MacIak]

Ultimaker series. I have stuff printed from those, really nice.

 

[sprtbkrydr]

Take a look for yourself. Why didn't I run the battery all the way down you may ask? I saw what I needed to the first 10 minutes of flight. Airdata says I had a 22 minute battery. If you want me to do a solid run I can but something was getting into my signal is the reason I turned around. I doubt that it will make much difference anyway.

Any compass or other issues on the Titan run?
