Which portable car charger do you have?It has been done YouTube is your friend for all spark hacks. I personally prefer 5 batteries and a portable car charger. I can fly all day long
No, there is not! Even if one could, it would severely reduce the mAh of the battery. You can REDUCE the 3.7v output with circuitry (as in the Lithium AA cells currently on the market).I'm sure there's a way to boost the voltage up to 11.1 with a circuit board. I don't know how to do it but I'm sure there's a way.
Hey thank you all for all of your interesting theories I am a newbie and because it is cold here in new York Have not gotten allot of Flight time. I am learning allot from you guys thanks.I am not sure what Mrmund's point is? This thread is about sparkhead43's question of how to increase the range or battery life...
The Spark battery is a smart battery and communicates with the Spark regarding voltage and fly time. Someone could possibly able to rig where it can draw additional power from an external battery source. A lithium CR123 rechargeable would be an option as it's lighter than a 18650. But then again it might fry the Sparks innards if not done properly.I saw the four metal contacts on the bottom of the spark battery and I was thinking that you could take two of those tube battery packs and put them on either side of the drone. Wire them up to the contacts somehow and have it charge mid flight. Also I would like to improve the range but there's too many cheap antennas online. Do you guys know of anything that actually works well and is reliable? It would be cool to slap a huge antenna on top of my truck and have a massive range but I doubt that's possible. Let me know if there's anything else I could do to improve my Spark thanks.

What's easier, wiring up a $6 battery or paying for a $3k drone? There is someone out there that knows how to do it I'm just trying to find them.sparkhead; forget your $600 Spark for any of your desires. There are quite a few drones that can easily accomplish what you are seeking. The bad news is they will cost you $3K to $15K!
Get lost!Any battery mods for the Spark I've seen are just ugly unprofessional looking hacks. Don't want my Spark to be the red-headed stepson
Well I'm that kind of person that could do it. You guys must remember the voltage of each cell shows its over 3 volt, the cells in the smart battery is up to 4 volts. If you check in the dji go4 app. A cr123 @ 3 volt won't do it, the voltage will be too low to even charge the smart battery. I've got an idea though that I'd like to try but don't have a spare busted spark battery. My plan is to use cell phone batteries of at least 3.7v each. I've got allot laying around here at home in different sizes, but I've got 2 specific cells here each 1 has more mah than a single cell in the smart battery and they small enough to fit inside The casing of the smart battery pack. The standard battery is currently rated at 3.8v @ 493.33 each cell, which add up to 1480mah @ 11.4v. The cell phone batteries I've got here are 3.7v @ 900mah each add them up and you get 2700mah at 11.1v and it'll all fit in the smart battery casing. One problem is I don't have a spare smart battery to do this, maybe if there's someone that has a busted battery could try this? Another thing cell phone batteries has is own charging circuit. That may be removed to make it a little shorter, the smart battery also has its own charging circuit.What's easier, wiring up a $6 battery or paying for a $3k drone?

Actually you can with a simple device called a Pololu. But you are correct, it's not able to increase the mah and in fact you'd lose about 15-20%No, there is not!

I think you are mixing up series and parallel configurations you get your 11.1vdc @ 900mah or 3.7vdc @ 2700mah only one or the other depending on how you configure your wiring.Well I'm that kind of person that could do it.

There is a major error in your understanding of what occurs when you combine battery cells in a series!.....When connecting your cells in Series you are increasing the voltage while maintaining the same capacity rating (amp hours). ....three 3.7v LiOn 1480 mAh cells in series = one battery pack producing 11.1v with 1480 mAh capacity!
Yes you absolutely correct, thanks for reminding mr. My mistake is, I didn't take that into account. In that case I got 3 sony li-po batteries here thats 2900mah each but that's a just little too wide for the spark battery caseThere is a major error in your understanding of what occurs when you combine battery cells in a series!.....When connecting your cells in Series you are increasing the voltage while maintaining the same capacity rating (amp hours). ....three 3.7v LiOn 1480 mAh cells in series = one battery pack producing 11.1v with 1480 mAh capacity!
If you find a busted battery and you're actually able to do this, make a tutorial on YouTube. As soon as you do that then people will be able to copy it and then other people who also know what they're doing can improve on it and make it better.Well I'm that kind of person that could do it.
