Hi all !
This is Fredo, with the FREDO_MOD result !!!!!
First of all, YES, it work !!!
Now, more precision on what happened.
Weather conditions: sunny, wind less than 5km/h, 15°C
What i did was a first flight with only one battery.
Start recording, took off, climbed to 150m and then circling in front of my position, always at full throttle forward.
I landed with battery alarm at 9% after 22min 13sec of flight
Then i changed the main battery by a full one, started the drone, plugged the second battery, attached it to the Mavic with some electrical tape turns, also some electrical tape to strongly attach the plug to 2nd battery, started the second battery, and started to fly.
Start recording, took off, climbed to 150m and then circling like the first flight, always full throttle forward.
I landed with battery alarm at 9% after 29min 22sec of flight.
Just after landed, the battery showed up 11% remaining.
After powered down everything and unplugged the second battery, i checked batteries level.
The main battery was a 11%
The second battery was a 28%
I recorded my screen during both flight for those who are sceptical. lol
What i think of this result:
I'm happy! For 10$ i increased my flight time by 7min !
- Why the battery gone down to 9% then immediatly showed (and stayed) 11%? I don't know
- Why the second battery only descended to 28%? I think it's because of the wires capacity and the flight i made. I was full throttle during all the flight! so the drone drained certain quantity of Amperes.
Everybody know that electricity will always choose the easiest way. So as my wires was smaller than the main battery wires, mine had a bigger resistivity, so the electricity passed more by the less resistive cable than by the more resistive cable. For me, that's probably why it remained 28% at the end of the flight. BUT, i also think, that with a more quiet flight, with some hoverings or slow cinematic pass, difference will be less. I should check it during my next flights test.
However, this is for me a HUGE victory !
Now @JustStig is on the way to make the best dual mavic battery holder never made.
And we are all entering a new era, where flying a Mavic more than 29min is EASY, and CHEAP, and don't need to disfigure your handsome Mavic.
Call it Fredo's mod or whatever but please, stop drilling holes everywhere, putting those ugly xt60 connectors, buying extra aftermarket batt and extra aftermarket chargers.
Ours Mavic are so well designed and so beautiful, respect them.
