I think on paper it would be 20a with 5 cells in parallel with each of them stated as good for 4 amp charge rate, but is that charge rate similar to discharge and we could consider a peak or continuous? I bet, and think it’s probably all related to how much heat is produced in the cells. I think a graphing of regen current at different amounts and time periods would show a similar curve as the discharge graph
surprised they would give out info so casually that could be so dangerous. I bet for short periods it would be fine at 40amps regen. how bout you get a temp sensor and hook it up to the vesc and your batteries and tell us what happens!!
Open up the specs sheet of your battery and see whats the max charge current and add like 5 10amps more since you will not be breaking full power all the time
Hope this isn’t off topic but how exactly does the VESC figure out what voltage to regenerate? Is there a step-up converter managing the recharging battery? Does the VESC turn excess power into heat since there is a battery regen limit?
the bldc tool has two variables for the brakes and I hear theyre similar to the amp output and have a “motor max” and “battery max”…I’m guessing the motor regen can be adjusted with the same limits as the motor max and depending on the vesc model it will likely have a 120 amp override limiting it, but you can adjust this to your heart’s content and its the battery regen which is the what is actually true regen and going back to the battery?
Charging current will be distributed between parallel cells, so that a charger providing 5a to your pack will roughly give each cell 1a charging current
(exact current draw somewhat depending on how parallels are connected).
