lipo cell balance ?
#1
i have 2 losi xcelorin shorty 3800 2s batteris that when i balance them it is showing the cells are off. is this a sign my batteries are going bad ?also the RES is showing higher then my other batteries. i have tried dischage and charging them and also storage mode still cells show about the same

can you balance them? i had batteries that were more off than that (cuz i forgot it in the car, and so it sat there charged for a week or so). I balanced it, and it then never strayed out of balance again.

The balance is really far of, but before you discard them check your charge/balance cables.
I once had a balance cable that had one of the connectors being pushed back a bit, making a bad connection. All of a sudden I had three packs go "bad", and some were still good.

It looks like the charger is displaying the total resistance, obviously not each individual cell.
Regardless, 146mΩ is very high. My yr old nanotechs show 1.9 - 2.2mΩ on each cell.
They say between 2 and 10mΩ per cell is good..
