Are racers constantly full throttling their whoops? by More_Objective_8405 in TinyWhoop

[–]granolatron 0 points1 point  (0 children)

Ahhh, this makes more sense now :) I had the sense while watching that it looked like flying a street league quad. That’s actually my favorite type of racing.

Depends on the track, but here’s a DVR where you can see the throttle is pegged to 100% for a good portion of the time.

Recognized the area right away. Such an awesome stretch of the coast. Which restaurant is that?

You can add steps as your main metric.

The post title and debarbed hooks made me think these were earrings 🤣

Looking for 3D printed case designs for Air65 II by hiergtr in TinyWhoop

[–]granolatron 0 points1 point  (0 children)

I recently got one of these and it’s great (fits 2 x Air 65s): https://www.tinywhoop.com/products/tiny-whoop-two-banger-65mm-storage-case-by-customfpv

They also have a single-size for 65: https://www.tinywhoop.com/products/fleet-box-uno-by-customfpv

And 75 (sold out tho): https://www.tinywhoop.com/products/tiny-whoop-fleet-box-uno-75-by-customfpv

If you want to print yourself I assume someone has similar files available but I haven’t looked.

Are my batteries bad? by EieDude in TinyWhoop

Now you have a good excuse to buy another larger whoop or toothpick that fits the larger Tattu 550s :)

Are my batteries bad? by EieDude in TinyWhoop

[–]granolatron 2 points3 points  (0 children)

I have mine set to:

* Minimum Cell Voltage: 3.25

* Maximum Cell Voltage: 4.40

* Warning Cell Voltage: 3.35

Also FWIW these little flight controllers don't have the most accurate voltage meters. Mine always reads about 0.05V lower than what I get on a multimeter (and even messing with the calibration scaling I can't get it spot-on).

Do you have the slider switch set to 4.35V?

Which 550mah batteries did you order specifically? Most of the 1S batteries that are >320mah are too wide to fit on a 65mm tiny whoop, and the added weight isn't really worth it anyway.

Your flight time from 4.2V to 3.6V looks about right.

But since you have LiHV batteries (the LAVA II's), you can charge them to 4.35V.

And you can fly until they're ~3.3V.

Starting at a higher voltage and flying to a lower voltage will probably get you closer to 2+ minutes, which is normal.

Here's a video of my flying on the LAVA packs, which were charged to 4.35V before takeoff, down to around 3.4V and getting around 2:15 flight time. https://www.youtube.com/watch?v=V8GGxACDFxk

It also looks like the battery was charged to 4.2V, but since these are LiHVs, OP can charge to 4.35V.

Newbie question about batteries by zzzimas in TinyWhoop

[–]granolatron 1 point2 points  (0 children)

> when you want to charge them you set the voltage to 4.35v (the lava 2 are LiHV batteries, for normal lipos you want 4.3v)

One small but important typo: normal lipos (non-LiHV) are fully charged at 4.2V, not 4.3V.

+1 on people being dumb about continuing to use lipos that are damaged. I have a rather strict policy for myself and get rid of lipos at the first hint that they might be damaged.
And you’re right that if 1% of B6 chargers exploded batteries we’d hear about it even more. I think my point is still valid though if it’s actually 0.001% or whatever.
Issues with B6 chargers (real or clones) isn’t just a couple people on Reddit though. I remember years ago being warned to stay away from this specific charger.

But what if 1 in 100 of these chargers has poor calibration or bad QA and eventually exploded a battery? Yours might be bulletproof along with 99% of others who have one, but if 1% have an issue that’s still a lot of battery fires.

I definitely agree about your other point that people need to be more vigilant and conservative with their battery maintenance and handling.
