Lipo Battery Cells Not Balanced

Suppose we have a 3s 3 cell lipo battery and the measuring the cells independently yields these results.

Lipo battery cells not balanced.

For instance from the photo below the balance connector of the three cell battery pack has 4 wires. 5 mω cell 3. The balancer only works to bring down the cell or cells that are charging a bit faster then the others. Just over a year now and this battery still performs great.

A lipo pack is charged thru the main leads. There s one additional wire that is the negative in the balance plug in comparison with the number of cells. What seems to have happened is your charger did not cap or limit the charging of one cell in your pack. 3ω 5ω 4ω 12 mω.

If the voltages across the cells deviate too much from each other 5mv 10mv the battery can become unstable and dangerous. Not the balance leads. Be sure that you unplug the balance cord. Unless it s a single cell lipo in which case you do not need to worry about cell balance.

3 mω cell 2. Just to be sure. Assuming we re talking about a single multi cell lipo pack and not a single cell or series connected set of packs your lipo battery cells are wired in parallel internally. To find the total internal resistance for the battery pack we would add up the values for the three cells.

It is crucial that all cells in a lipo battery maintain the same voltage across all cells at all times. Update this worked perfect i have used this batt many times over now with zero issues. Enter a low a value around half the battery capacity. Why do the packs have to be balanced in the first place.

Hence the 14 8 volts battery would possess 5 lead balance plug and the 18 5 volts battery owns the balance plug of 6 leads.
