I started a built and obviously one thing I needed was batteries, but I’m just really surprised by the results I’m getting. This is what I did:
- Install a power measurement unit
- Put the propeller in a bucket
- Run it for as long as I can
The battery is a 6s4p 22ah FiJiLa, I selected these because they are supposed to have a higher rated continuous discharge. But the truth is that it seems more like they are on the low 5ah.
They basically run for 1h to 1h10 at 3.5 to 4 amp (80w drawn).
One thing I noticed is that as soon as the battery is under load the power drops significantly (maybe one volt).
Anyway the question is, am I doing something stupid, or the product is crap?
