Zeee 4S 7ah. A year or two old. Little bit of puff but not too bad. Balances slowly but successfully.

Try charging at 5 amp or 6 amp. The swelling might go away. Cell 3 does not look OK. How is the power and run time? Keep an eye on temp running and charging.Zeee 4S 7ah. A year or two old. Little bit of puff but not too bad. Balances slowly but successfully.

Great information dude!IR values will be obscured while in the charging state, charge it up to .. then let's see that value, after that, throw it in a rig and run it for about 10 mins and then throw it on the charger again, observing it's behavior for a few cycles will give you a better idea.. anything above 20 milliohm's is "cooked" they say
Yup I say the same .out the door it goes .take noooooo chancesI will get rid of any battery that shows the slightest sign of puffing. My house and family are worth more than buying a new battery.
Contact the lipo company before you toss it. See if they will warranty the lipo for you.Should I keep the good three cells? They seem to be in great shape.
Has anyone done that and/or know of a good tutorial?
