I was running some amp tests on my EMAX CF2822 1200v motor using 20A esc and amp/power meter
Why would the battery go so low in voltage under load ? Same thing happened with the 10x4.7SF on the Zop battery
The Zop batteries are rated 25C and the Nano Tech 25C/50C burst so should be able to go to 25A for Zop and about 21A for Nano Tech.
(Recharged the Nano Tech battery back to 8.1v before doing the 10x4.7SF test)
First, do those number seem correct ? first time using the power meter.
Second, I'm trying to understand why the battery goes from 8.1v to below 6v under load that so that I can select the right combination of Motor/Prop/ESC/Battery for my planes.
