lipo cell balance ?
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

I would say they're dying. They shouldn't be that far out of balance.
Age has much less to do with Lipo life than how you treat them does. |
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.

Not familiar with how the resistance values from that charger compare to others, but at first glance a resistance value of 146mΩ is very high.
|
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.. |
Ok thanks guys I had been using them in my 17.5 buggy and seen a big difference in punch over my reedy shortys.guess ill start using these for my scx-10 crawler.
