you are correct on battery on/offFor my info:
- during startup the ext batteries are plugged in AFTER mavic is on
- during switchoff the ext batteries are plugged out BEFORE mavic is switched off
Is the above correct?
@cruzroy: hitting that spot would be awesome. It's big, hard to miss you'd say.
Thanks for the vids by the way. Have enjoyed them (especially the drill n chat during FFWD)
so if you took a grind wheel and ground down the plastic a hair above and follow the rail on the sides to grind to the soldier joint on top attach wires and hot glue.
Confusing, I know but, the only damage done to the battery would be on the top next to button 2 small strips missing and 2 wired leads would only be in maybe 1/2 in not thru and around to inside housing of battery.so if you took a grind wheel and ground down the plastic a hair above and follow the rail on the sides to grind to the soldier joint on top attach wires and hot glue.
Not for sureYou guys think there's any room for the power lines to come out the side on the battery??
Lipos are fine. It is only the multistar lipo that doesn't work well. The advantage of Lihv is more power to weight ratio. Lihv cells also match the Mavic better because Mavic uses Lihv as well which has peak cell voltage of 4.35v rather than 4.2v for lipo. The downside for Lihv is that you need to be careful when charging to slightly undercharge it to only 4.32v/cell or less. If you don't there is a chance that the voltage will exceed the Mavic battery which can cause Mavic to switch off the main battery. The symptom is that you're flying and notice the battery gauge is not dropping. This means the Mavic battery is off.
This only happens (in my experience) right at takeoff, so you'll see battery stuck at 99%. Just a fyi as 2 of us lost our Mavic this way, by continuing to fly and later having the external battery run out suddenly with a critical landing which is more like a controlled crash landing.
This is how I connected it.
I think you are right that it creates one big battery. I just did another test where I only had the LiPo batteries on and the mavics battery off this turned the drone on but the mavics battery did not show any signs of charging. The reason why I thought it charged the mavics battery was because I thought that the battery was charging when only the LiPo's were on, I saw wrong, my apologies. Another thing to note is that as expected the mavic will not connect to the controller unless the smart battery is turned on so when that is low the drone must land. This is probably the reason why the LiPo's can last three flights, due to the fact that the smart battery dies first.
Was wondering where could I purchase this adapter at...thanks in advance.....

after dremeling out the inside panel to reveal the power leads, I too thought there was a possibility to come out the side, and there is. But you have to be extremely careful because there's enough room for the wire if you drill through the side, but put it on a vice and drill press so you have complete control, I tried to freehand and you'd be surprised how close the thin battery cells are after you break through(maybe even free handing a Dremel sanding wheel would be better) I must've punctured one of my cells, I noticed a strange smell coming from the battery, and was hoping that it was only the foam and cheap plastic. I flew that battery on two different long flights with no issue. The next time I fired it up I had a cell that was .30 lower than the rest and gave me battery errors. So yes it can be done out the side and would be ideal but use caution. From what I can see no more caution then going on the top. The whole thing is tight, and because I had that battery to spareI tried to figure out how to crack the case and I learned a couple things but never how to get in.

Yes, perhaps I can simply turn the battery to an angle to get the front part of the battery up, away from the front legs. It's also possible I just had bad signal for that flight. It happens. The route is not precise.
The antenna's are in the front legs, and aren't even close to your batteries so I'm not sure why they would make any kind of difference.
LAST NIGHT FLIGHT.................mavic pro, backpack mod, did not push, but easy 31 minutes, i did edit out the 2600 ft return across the lake, i figure nobody wanted to look at water......the minute it was over head, it went into low battery.....but not yellow H yet....so maybe 5 min more......no high speeds, maybe top 20 MPH.....love this bird
Uhh..if you re crabbing against the wind at low altitude your line to the drone is almost horizontal. 1 or both of your leg antenna's will be completely blocked. 5cm of polymer surrounded by foil will absolutely ruin your reception completely.The antenna's are in the front legs, and aren't even close to your batteries so I'm not sure why they would make any kind of difference.
Hey bud,LAST NIGHT FLIGHT.................mavic pro, backpack mod, did not push, but easy 31 minutes, i did edit out the 2600 ft return across the lake, i figure nobody wanted to look at water......the minute it was over head, it went into low battery.....but not yellow H yet....so maybe 5 min more......no high speeds, maybe top 20 MPH.....love this bird
