Lighter battery

[MyLittleDrony]

I need the spark to be as light as possible for a project, but there isn't a whole lot of weight in the spark to play with , but one of the most obvious areas of interest is in the battery casing.

And then I thought....

Would it be possible to take away some 1 or 2 of the 3 cells and just have a drone which flies for a much shorter period of time, if this is possible, does anyone know if its just as case of ripping a cell out, or is it (I suspect) much more complex than that?

Thanks

You are correct...these are way different than the FPV racing LIPOs that some of us use.

The cells are run in series in order to give the volts needed to run everything. A 3S battery (which the Spark has) is ~12V, if you took away one or two, it would drop to 8v and 4v respectively. You could probably get away with smaller cells, but then you would need a higher C battery in order to match the output.

You are right there isn't much to shave off. Suggstions I would have all rely on the body. Punch holes in the arms, the body, the top lid, the battery casing. But even then, probably just a few grams, not sure it would do much. Modding to a smaller battery for very short flights might be your best bet.

GR8 reply thanks.

There is an Italian company modding the Spark to weight 299g, but WITH prop guards! This way, it can be used in Italy where otherwise, drones would be prohibited.

I am not so concerned about weight, but I would sure like a longer flight time on my Spark. Does anyone think DJI will eventually upgrade technology to allow the spark to fly longer?

Not likely - that's how they get you to buy the next model!

What's the company? Got my ears up at this xD

Doubtful, at least nothing significant. I'd see it getting lighter, but being crammed with more tech (such as rear sensors), which require more CPU, so more energy.
