Parasitic current draw of various ESCs and accessories

…and @Skyart…it depends on the chemistry and cell but around 5%-10% is left between 2.5V-3.0V. There is verrry little available below 2.5V.

IMO we should consider 3.0V (or so) as “empty” and 2.5V as “dead” though. Yea, it’s nit-picking but we need to avoid any conversation regarding going below 2.5V as that always leads to wanting (or learning how) to revive a pack…which should never be done.***

***We can choose to revive any pack of our own, I’d never try to prevent someone from choosing the level of risk they wish to take. But I strongly urge everyone to never advise anyone else to do it or to even mention that you do it. We’ve got enough battery issues to worry about already.

Should this also mabe be tagged in safety, product warnings and Esk8 Dev?

There isnt a wikki as such is there? Excellent research @jaykup , as a result of this ill be adding a loop key on my flux.

Mad respect for getting measurements in the uA range!

So we tested the ubox v2:

The resistor is 56K+2.2K, drawing current will be 72/58.2k=1.24mA for one ESC. Two ESC is 2.48, the rest 20uA is from the setp down circuit.
