I have started making a few of my own batteries out of 18650’s and need to know what is the voltage you would land at and also set the alarm in Betaflight?? Also an 8 pack I ordered had 2 batteries that were dead. One read .9v dc and the other read .5v dc. Is there anyway to revive these batteries? The company gave me my money back for the whole 8 pack and I just wanted the 2 batteries replaced!!
When I use lI-ion packs I consider 3.4/3.5 my halfway point and usually turn around there, that gets me back home around 2.9/3v
you can go as low as 2.6/2.7 so there’s a small buffer in case of wind resistance on the return trip
