Mavic Pro Battery Mod

[cruzroy]

I don't get it.. Why is this mod ok to talk about, while others are not?

i think all forums are talking about modding firmwares, not the product .......for now, like there are 2 firmwares that remove NFZ in mavic spark and phantom 4, that would alter products design , but not sure

So opting for 1200-1500mah which are the lightest? It seems that at these mah only lipo are available and not lihv!
I do not want to go over 280grams in total.

all newer drones work all on firmware not hardware like old NAZA based DJI, so the right mind can rewrite the firmware, i have heard people complaining about DJI privacy rules.... how you upload all your info to them like the cloud, and they just dont want to do that.......so.......just examples, but i think if you want to add bigger props or a better antenna, thats ok, i quess we all need a better explanation of the rule, so none of us cross that line,

most hobbies are about tinkering, and making a better mouse trap

Can you publish the exact volts you see after your runs so we can compare effectiveness? Thanks.

Just got back from a run and the flight ended with main battery on 8% and both outboard batteries were dead on 10.77 volts. I'd say I got the best out of those that time! Oh and flight time was 29 minutes.

Turnigy offers a 1300 in a LiHV 3s pack.136grams each. Goto Hobbyking.com and you'll see it there.

Which batteries did you use on that test run?

Zippy 1300's

What was the genesis of this rule? Did someone get hurt or sued? I totally get the NFZ safety concerns and support that, but I would like to be able to discuss if there is a software knob that could tune wireless settings, or a knob to change the LED patterns, etc, etc, etc. Me need some mo tinkering

But modding the power system, playing with LiPo batteries is just fine. You know, for everyone's safety... The real reason for these things get kinda obvious after a while you know.

If you don't feel comfortable doing it then don't. Nobody is pushing it on anyone.

Anyone know where that ole frowning clown(Maclak) has been?

beanbubba you have any numbers to compare yet?

I have not yet tried a test run with only the soldered battery clip (I have been combining with the internal bypass). I will do one tonight and report back.

 

[sprtbkrydr]

OK sounds good. I haven't got the nerve up yet to do a long distance night run!

 

[beanbubba]

beanbubba you have any numbers to compare yet?

Wow! Two drops of solder makes a big difference. Flight time almost 31 minutes. Dual 1500 lipo's came back at 10.6v each (picture was a couple minutes after I attached the charger). Main battery at 7%.

For our friends that are not interested in doing record setting runs, I think the dual 1500's are right in the sweet spot. And if you can get the LiHv versions, even better!

I bet the battery bypass method can only perform incrementally better than the soldered clip. I will do the same run/test on the battery bypass after these charge up, then compare numbers.

 

[sprtbkrydr]

Just about the same exact numbers I was showing after my run. Interesting. I don't see how the hard wired mod could do much better than this. Be interesting to see what the next set of numbers are.

 

[sprtbkrydr]

I've got a set of 1800's coming in a few days that I want to give a try.

Probably not. I however am planning my next long haul range run using both the clip and bypass with a yet to be determined battery type/combination. Game on

it's all what makes the hobby that much more fun,trying to just figure it out.
