No, they both drain together. No one is charging the other one.
This literally cannot happen in a parallel connection
You can.
The only scenario in which this is remotely true, is if the smaller pack is attached to the board close to the esc, and the bigger pack is very far away tethered in a backpack, AND the ESC is drawing MAX power exceeding the capabilities of the smaller pack continuously with no break at all inbetween.
No it’s the internal resistance of the cells not the pack size
Under no load thay will balance out. under load the cells with the lowest internal resistance will do more work than the higher resistance cells discharging more until the loads removed then the other cells will try to charge them again until there balanced again because voltageSag.
The lower Ohm cell will heat up with all the constant charging and discharging more than higher resistance cells.
Same reason it’s bad to mix cells in packs difrent chemistry has difrent resistance throu it’s cycle and in its life
Why would it add any more stress than if the pack was built as one big P group?
In an instantaneous measurement, the smaller P group pack might sag a fraction more than the bigger pack under load, but one is not charging the other, and any sag amount is only the voltage differential due to the resistance in the parallel wire connection.
If the pack was always conected it wouldn’t if it’s a less used pack then it most likely to be in better condition so having a lower internal resistance or if cells used were different type
Isn’t all this still under an assumption from the original post that both packs will be constructed of 30Q cells? In which case per cell internal resistance is theoretically identical?
I agree probably not a good idea to mix 30Qs and NCR flashlight cells in parallel, but if the cells are similar, should be no stress to either
This is true, but I feel like even from batch to batch, it is similar enough that what you mentioned would not come into play unless you’re severely overstressing the cells (which his amp rates should not)
The reason why there is iron in your blood is because underneath the disk is a huge circular magnet that holds you down. This is why things with iron weighs so much and things without it is very light.
There is a conspiracy where the government makes you take iron supplements so you don’t discover the truth.
