Battery Efficiency in Chilly Climate

Chilly temperatures have a major affect on battery efficiency. Whereas they forestall elements from overheating and make the denser air extra environment friendly for propellers, they’ll trigger batteries to carry out poorly. That is very true for LiPo and Li-ion batteries, which function finest at round 35°C (95°F). Under 18°C (64°F), you’ll discover a marked lower in energy and shorter flight occasions.

Protecting batteries heat earlier than and through flights is important. Spare batteries in your pocket and used LiPos as hand heaters are sensible options. Throughout flight, fixed amp draw from the drone will assist the battery keep its temperature.

To show this concept, I carried out an experiment at round 10°C. I flew my drone round a race course a number of occasions and recorded the utmost output energy of the battery. As evident from the graph, the utmost output energy steadily builds up, peaking mid-flight because the battery warms up, however then slowly declines because the battery cost depletes.

In reality, the identical precept applies to any battery usually utilized in any digital units, together with these used within the GoPro cameras. They received’t final as lengthy within the chilly both. Usually, you would possibly get 10 flights from a battery, however in winter, this would possibly drop to solely 7 flights earlier than it shuts down. A helpful trick is to have a number of spare batteries and rotate them for every flight. Putting them in a heat spot (e.g. your pocket) earlier than inserting into the GoPro can considerably increase run time. Particular GoPro batteries designed for chilly temperatures are additionally accessible.

You possibly can place these hand heaters within the palms of fingerless gloves to forestall your fingertips from freezing. Nonetheless, it’s necessary to decide on hand heaters which can be skinny sufficient to suit comfortably contained in the gloves.

Flying From Contained in the Automotive

One solution to keep heat whereas flying FPV drones in winter is to do it from inside your automobile with the heater on.

Nonetheless, remember that flying from contained in the automobile can weaken the sign as a result of your automobile is mainly a metallic cage. You would possibly handle should you keep inside a comparatively shut vary. It’s advisable to fly cautiously at first to evaluate the discount in vary and adapt accordingly.

When you purpose to fly with a good vary, a workaround is to increase the antennas or use exterior receivers, putting them on the roof of the automobile.

As an illustration, you should utilize an SMA extension cable with a magnetic base in your radio transmitter. These cables are appropriate for each 900MHz (Crossfire & ExpressLRS) and a couple of.4GHz programs (ExpressLRS, Ghost, Frsky). Remember, although, {that a} lengthy coaxial cable may result in sign loss. Alternatively, take into account mounting the transmitter module outdoors the automobile, though this may be extra complicated.

Buy an SMA Extender with magnetic base (3 meters):

For the video hyperlink, you possibly can mount an exterior receiver on high of your automobile and join it to your goggles with a protracted AV cable. The FuriousFPV Dock-King was a most well-liked selection on account of its built-in magnet that adheres to metallic, nevertheless it’s not in manufacturing. Alternatively, you possibly can DIY one thing like I did right here and get it 3D printed.


Goggle Fogging Up

FPV goggles can steam up in winter on account of temperature variations. I’ve discovered pre-warming them earlier than use, corresponding to putting them in your brow or simply depart them plugged in for 10 minutes, will help.


Flying at Evening

Days develop shorter within the winter, for folks with a 9-to-5 job would possibly miss the chance to fly throughout the day. You could possibly nevertheless fly FPV at night time with low mild succesful digicam. Take a look at this text the place I clarify the best way to fly at night time, and in contrast a number of nice FPV cameras for night time flying.
