The three way simple regulator solution @rickyg32 posted is the simplest of all for your FC, however note it only provides +5V switching.
For another device power redundancy, it depends on how much voltage and current you need?
If you are willing to burn money, you can look at Mauch Electronics dual battery redundant design. You can customize what output voltages you need. They will custom manufacture the outputs for 5 or 12V which is typically the requirement all devices used on UAVs.
I am using another trick where I also use two FrSky Lipo Battery monitors along with Yaapu Telemetry. This way i can keep an eye on each battery individual cells during flight (which is another cause of major failure, where one of the batteries cell voltage will drop below threshold) even with Mauch solution which doesnt offer any cell level voltage monitoring.
Please note, the batteries are rated to 3C which means 36amp max discharge
On my little beast which uses 29amp/h and 40amp/ when I push it a bit one battery is not enough.
Though I did all my AT with only one (8000 lipo couldnât do even 1 axis AT)
A few things
You need to find the data sheet for your batteries where all data is shown.
From what I just read your batteries are similar to mine but they suggest not to discharge faster than 2C
If you consider that 1C is (in your case 3200mah and not 3400) it means your can use something that uses 3200ma for one hour withe 1 batter, right?
Now, in your case, your battery can safely discharge 2C, so if you now double the load on your bat with something that uses 6400ma, your battery shall last only 1/2 an hour.
Also, I see you built a 6S2P battery which theoretically should give you a 25.2v 2C 6S 6400mah.
Not enough power might mean bad soldering or incorrect wiring. Show me both sides of the soldering
My batteries are soldered with nickel stripes and a balance cables are a must have unless you use internal battery manager and thatâs a no go with the chargers I use iSDT
Hi UAVSkies,
If I may suggest, donât ever use Chinese LiOn for drone. Based on my experience I may recommend LiOn battery for drone are :
Option1: Sony 18650 VTC6 3AH with 10C max. discharge rate
Option 2: Sanyo (now become Panasonic) 18650 GA, 3400 mAH with 10A max. discharge rate
Option3: LG 18650HG2 , 3 AH with 20A max.discharge rate
Well, youâre never supposed to get that hot unless you didnât do the math correctly.
If you calculate your battery pack to go up to 3C, I recommend 3C to be safer than sorry.
So for example 6S 2P based on the VTC6 you get a 6200mah of which you use motors that can max pull 18amp 1c=6200 / 1000 = 6.2 amp//h. If you plane motor use for example 5amp/h in 50% throttle then your battery can last for about an hour and change
Than I would use nickel strips 1mm thickness and donât use wires except for balance wires. Make sure you place some isolation between the sharp edges of strips to the balance wires, they are very delicate.
After soldering wrap it in cardboard from all sides to protect and hold everything in place and use strong duct tape or similar but non metal.
Hello everyone. I have a Skydroid T12, I have a problem with Skydroid Tower, I use version 6.4 all connected receiving gps telemetry with more than 6 satellites but in Tower the map does not appear, I have reviewed everything I could but I cannot find the solution. It also happens that when I start slydroid Tower it tells me there is a new version 6.6 but even if I accept it it does not update it and in google paly that version does not exist ⌠it is all a mess. I would appreciate help. a greeting
Hi @Guillermo_Sanchez, your tablet supposed to be connected to the internet so QGC or tower can update the maps. If I remember correctly in tower you can select the map provier beidu or google
HTH
Gal are you building batteries,
I am just about to order a bunch of 18650âs to build a battery pack. But I confess I have never built one before. I do have a spot welder and the needed supplies so hope to get at it shortly.
Here is my pack design.
WOW Ricky, that is a very beautiful design, much more sophisticated than mine.
I am not a professional⌠watched YT like anybody else. However I am technicalâŚ
My only suggestion is to use the Murata 18650 VTC6US. Combined with careful planning of the vehicle electrical requirements you would get exceptional results.
GL and do share some photos of the results or even some from the build.
If confirmed, you are connected to the internet. QGC if the maps work. confirmed google maps does not work, I have configured maps (Chinese server) and it works although that option is only in tower v 6.0 does not exist in version 6.4. Also say that you insist that there is a version 6.6 but even if you agree to update it does not, in Google play the latest is 6.4
