Plan suggestion for 18650 battery.

#2
That would seem like a very heavy pack for a 3cell model. It strikes me that the power required to keep the model in the air is limited by the pack rating of 15/20 amps. Maybe an FT Guinea Pig might work but I would not be too confident.

The only thing with 18650s that I've gotten to fly is the Nano Goblin from Strix. Everything else, i just don't see it as a viable battery pack for the weight.

For a 3P pack, you should be able to do 60 Amps...... There is an inverse trade off between C rating, and mah. Somebody has been playing with 18650s in a Strix Stratosurfer, and has it up to about 50 minutes of mild flying. 18650s are great for endurance, but not great for speed/power.

I'm working on a similar pack right now for my sea duck. I've been flying with a 10,000 mah lipo that weighs 1lb 9oz and I can cruise at about 8-10 amps continuous. I think I can get that down to 5 or 6 by refining the wing in my next build.

a lot of long range flyers are starting to use 18650s
the C1 Chaser wing guys are using the 18650 packs and reporting 45 min- 1 hr flight times
due to the low power management/consumption of the long range flyers trying for distance

I too have been looking into this am going to build a pack to test against a couple 4 cell lipos to test in my C1 wing
I am already using 18650's to power my taranis radio and also the R9M long range module
I have a 56volt ego battery with a few bad cells that I should look into scavenging batteries they are not 18650's but I will look into this too???

lets us know your results

hahha yeah dont believe the specs.
the first pack I soldered up was with cheap Chinese over rated batteries I scavenged out of something, it could only spin the motor for a short time as the voltage would drop so fast, so I use them for low demand transmitter batteries instead

this is where you really get what you paid for

normally,cheap ones is "cheap effect", if want effect as said up here, continious amps over 25-30, you never get it by cheap batterys ..and every battery with named something with "FIRE" is that, easy bust in fire..
