Lipos for Altimeters

cwbullet · Dec 7, 2022

I know this has been done before, but I want an update thread with supply chain issues.

What lipo do you use:

RRC2, RRC3:

Turnigy nano-tech 300mAh 2S 35~70C Lipo Pack

Turnigy nano-tech 300mah 2S 35~70C Lipo Pack

RRC3:
Stratologger CF:
Marsa:
Altus:
Eggtimer:

The bottom line is I want to update a stick to make it easy for folks to find the info. Name the altimeter and battery, and I'll add them to this post.

I use the RRC2, RRC3, StrattologgerCF and the eggtimer altimeters. I use this one for all of them.

I've had lots of success using the listed LiPos with the following altimeters.
RRC3: Venom Fly 7.4V 430 mAH or 300 mAH
Eggtimer Quantum: Venom Fly 7.4V 430 mAH and 300 mAH, Crazepony 7.4V 400 mAH.

+1 the turnigy Nanotech 300mah 2S for everything Eggtimer, if I need to fit something into a tight package a Turnigy Nanotech 180mah 2S.

Missleworks is still 9v because its recommended by Jim Amos.

I purchased a few of these:

https://www.amazon.com/VICMILE-Battery-1200mAh-Rechargeable-Compatible/dp/B09K7V4N61/ref=sr_1_8?crid=13KG82OAV9027&keywords=vicmile&qid=1670469433&sprefix=Vicmi%2Caps%2C101&sr=8-8

(vicmile 2s 1200 mah)
for my eggtimer quantum and stratologger/eggtimer miniswitch. It's got separate jst, ph2, and charging connectors... just a bit longer than a 9v.

For anything with GPS, I use these

Ovonic 2s Lipo Battery 50C 1000mAh 7.4V Lipo Battery with JST Connector for RC FPV Racing Drone Quadcopter(2 Packs) https://a.co/d/cqAZ1pN

For just deployment devices I use 450mAh of the same

Handeman · Dec 7, 2022

I have Perfectflite CFs, SL100 and HiALT45. I only use 9VDC batteries for altimeters, never LiPos

waltr · Dec 8, 2022

For Eggtimers and Eggfinders:
300 to 400mHa 2S LiPo with high C discharge rating (this ensures it will deliever the Current requesed to fire ematch or igniter).
I use 300mAh nano-tech but also other brands with similar specs.

(found three NIB even though they've been discontinued for some time, I've not had any issues with charging/capacity so far (Powerlab 8 charger))

I think you miss the point of using Lipo - they are rechargeable and weight less. A 9V will not even fit in one of smaller rockets.

cwbullet · Dec 8, 2022

Could the stratologger work with a 1S battery? I saw this question from the past.

I think it’s been stated that they can as long as the voltage is above the minimum threshold of the stratologger. Spec sheet says 4-16 volts.

I understand about using them in small rockets. I don't have anything that small. I opt for 9V because they are NOT rechargeable and last several years in an av-bay before dropping to 8.9V. Since I seldom open my av-bays, that works much better for me.

Try the regular Turnigy batteries or Zippy batteries. Both are sold by Hobby King.

Try ship from Global instead of USA. It will take longer, they are probably coming from China, but they are In Stock.

Check Adafruit.com for LiPo batteries.

waltr · Dec 8, 2022

There are also a number of smaller RC airplane/quadcoper on-line stores that have small 2S LiPos.
A google search should find a few.

I do buy LiPo's from Adafrut but if I remember they only have 1S which I use in small rockets with DD since I can get two on the back of the ebay sled wired in series.
These have a different connector so be sure to buy some of the mating connectors with leads from Adafrut when you buy the LiPos. They also have some nice 1S LiPo chargers that are powered from USB.

I use those as well. They are the same size as the turnigy ones I use. I need them to fit into my sleds so size is important to me.

Yes, and it will cost $72 to ship $20 of batteries. No thanks.

Try this one. It's not a LiPo, it's a LiFe, which is a safer chemistry. I've been using 850 mah LiFe batteries for receiver and servos in my RC planes for the last 10 years or so with no problems. And, it's in stock.

I've been really happy with the Rhino 300mAh.

https://www.amazon.com/HobbyKing-Rhino-300mAh-Lipo-Pack/dp/B07RNZDKB8

Two things I like about this (vs most other small 2s batteries)
1) the standard XT60 connection. this is such a ubiquidous connector, you can find converters, or make your own so you don't have to cut the wires coming off the battery if you don't have the proper connector for your altimeter/gps/computer/etc...
2) The discharge rate - 50C !! Has no problem even the largest airstart motor starters.

waltr · Dec 8, 2022

All those other batteries will work fine.
I did check the discharge rating on the LiFe and it is 20C so 16Amp and will fire any ematch or igniter.

Banzai88 · Dec 8, 2022

Plenty available on Amazon: https://www.amazon.com/TURNIGY-Nano-TECH-300mAh-35-70C-Battery/dp/B07L37LZD5/ref=sr_1_4?crid=S8JRIHSGQPCD&keywords=turnigy+2s&qid=1670538833&sprefix=turnigy+2s,aps,114&sr=8-4
