We can build a real electrical car out of the left overs I think.
The interesting part is that this battery (which is the one I found exactly in my unit) only has a 1.0 C-rate, meaning its build to deliver 0.8A without considerable voltage drops or reduction of rated lifespan. Internal resistance is 180mOhm meaning that if you draw 4A from it (with 2x BuWizz and stock current limits) you are looking at LEAST a 5.71% voltage drop (using ΔV=I×R in practice the drop is more). At least explains why the battery level is diving down in the app when going maximal throttle (battery level is measured by reading out its voltage, 3s lipo is full at 12,6 volt and ‘empty’ at 9.9 volt😁 You can even get below the critical battery discharge protection point and shut off the whole unit doing this. A battery with a 1.0 C-rating is not made for purposes like this. Actual RC lipo batteries have C-ratings of 60 for example and are able to deliver 120A without problems.
What they shoud do to work around it is to dynamicly adjust the max output current accordingly to the battery charge to make sure they don’t hit the discharge protection. So at max battery level its 2A per channel, at 80% 1,5A, 65% 1A at 50% battery 0,8A per channel etc —> I have not calculated these values just some examples, but its not that hard to calculate it.
I’m running my unit on 1A per channel which is okay I guess but would love some more performance on high charge without to risk of shutting down my device when going full throttle on a battery with 60% charge left.
