I’m the owner of an Iris+ and i recently build a mini quad, since I’ve bought six of the original Iris+ Lipo’s some time ago, i would like to use them on my mini quad as well.
But now I’m really confused about C-Ratings
If i understand this C-Rating correctly it calculates the Max current A coming from the battery. So in case of my Iris+ battery with the max of 8C with 5100MAh
it results in 5.1 * 8 = 40.8 A
does this means, the iris+ will never require more than 40A current ?
Some time ago, my original 4in1 ESC burned out on 1 channel and i’ve replaced it with 4 DYS-SN20A, so far so good.
For my mini quad, I’ve choosed the nighthawk EMAX frame and the same ESCs with the 2205 from T-Motor (2205)
Within the Set they are using ESCs with a max of 15A but i can’t find specs about the real max current of the Motors.
But know to my issue, as soon I’ve start flying, the quad land’s after short time and inspecting the logs showed it is related due to Battery Failsafe:
6: Battery failsafe
ECode 1: battery voltage dropped below LOW_VOLT or total battery capacity used exceeded BATT_CAPACITY
The battery dropped down to 9.8 V.
- Is the battery with 8C to weak, or are their other possibilities which i should check first ?
- If it is too weak, which batteries should i choose for ~15 min flight time ? (atm, the overall weight, with the Iris+ battery is 846g)
- do the higher kv motors require higher C Ratings ?
Many thanks in advance for your help
