Did anybody came up with a good recipe for charging the batteries in the car?

This is the one that I purchased, and it works fine. Not sure I would recommend it for daily use, but for the occasional charge, it has served me well.

I have one of these there cheap and work great http://www.ebay.com.au/itm/18178 ... =STRK%3AMEBIDX%3AIT

I hear that it needs to but "pure sine" (or something like that) or you can burn the P3 battery.

The link you sent is not "pure sine".

I had purchased one similar to yours but returned it.

hmmmm this is very interesting and makes a lot of sense.

I wonder how safe it is.

Thanks.

Inverters are clunky and wasteful.

Just buy a Phantom 3 car charger for $under $20.

Very nice.

Have you ever used any of them?

My inverter and charger can charge my 2 batteries in the car in less than 50 minutes.
The item above takes 60 minutes for a single battery.

Which one is that please?

Both.  They both work fine.

Cool. Thank you.

is the battery itself smart to stop take charge when its full? so it will not overcharge in the car? or?

All of the charging circuitry and cell balancing is done IN the battery.  (This is why there are battery firmware updates....  To update the charger's computer... located inside the battery.)  These power supply cords simply apply a raw 17.5 volt DC voltage into the battery's onboard charger where it is modulated by the battery's computer to correctly charge the cells.  The actual charging is controlled by the onboard charging circuitry built into the battery.

i use a 150 watt inverter and a 500 watt inverter.  both work well but the 500 watt version will drain the battery if not careful.  i also have an 800 watt generator for when camping or stationary for a while

Yes... Using an inverter to make 120 volts to run the 120 volt battery charger which tips the voltage back down to 17.5 volts is hugely inefficient.  You probably are wasting half of your car battery just running the inverters and adapters.

The Car chargers are much more efficient running off a car battery.

I really like my 800 watt generator.  The car charging is just in case.

You really should go with the power inverter and use the DJI charger

I have a Duracell 130 watt continuous inverter with two plugs and it handles two chargers without issues.  I also have a Belkin 300 watt continuous and it cannot even charge one of them.  Anyone have any ideas why the the stronger Belkin cannot even charge one of them?

I have a 400 wt inverter in my truck hard mounted... works great... appx $40

if I was charging in a car ,, I would use a Li-Po Battery Fireproof Bag ,,, better safe then sorry ,, most are $5-$20
I always charge in a bag ,,, I had friends with Chopper's and Airplanes have the Li-Po's burst ,, never heard of a DJI battery burst yet

Fulgerite is correct; why transform your 12V DC up to 120 or 240 V AC. only to have the official DJI charging pack have to cope with that imitation mains electricity and transform it back down to 17 Volts DC, when all the charging protection circuitry is in the battery itself?  Hugely inefficient and risks damaging the charging adapter.

I've used a cheap ebay car charger for many months with no issues at all.
