Battery doesn't want to fully charge

Doesn't want to?

Quit giving it a choice, be firm with it!

I am not giving it a choice
I put it on the max charge settings and still can't charge

Storage charge it. Then charge it.

Storage charge it. Then charge it.

I'll try that after dinner

At the track last time. it did the same thing right after storage charging it.

The other battery in the pair is still good.

What's the balance current rating for your charger?

It's clear your cells are degraded and no longer matched with the IR being 1.4mΩ apart, chances are it will eventually balance but is clearly taking longer than you prefer.

Some chargers will let you disable the balance mode and charge to standard 2S voltage at 8.40V and that will gitterdone knowing the cells aren't matched and they'll discharge unequally regardless. Just know that the battery is on it's final leg and the time has come to replace it.

Chances are a charger with a higher balance current rating will make the battery limp along a little farther but for stock racing I wouldn't race with any cells higher than 2mΩ if you want to get the best possible performance out of the pack.


Good Luck!

So those voltage numbers are after a balance charge timing out? What is your time out setting? Same thing happens on channel B? I don't think it does, but does the charger have calibrating setting?

If the constant voltage part of the charge is "taking forever" to complete, then most likely the cells are far apart in terms of health.

Did you try storage charging it?

Did you try storage charging it?

I did
And then did another balance charge cycle and did the same thing
I have the same problem with other batteries too
Time for new ones
