Lipo Battery Cells Not Balanced

To find the total internal resistance for the battery pack we would add up the values for the three cells.

Lipo battery cells not balanced.

Just over a year now and this battery still performs great. It is crucial that all cells in a lipo battery maintain the same voltage across all cells at all times. Suppose we have a 3s 3 cell lipo battery and the measuring the cells independently yields these results. Just to be sure.

A lipo pack is charged thru the main leads. Be sure that you unplug the balance cord. 3ω 5ω 4ω 12 mω. For instance from the photo below the balance connector of the three cell battery pack has 4 wires.

If the voltages across the cells deviate too much from each other 5mv 10mv the battery can become unstable and dangerous. There s one additional wire that is the negative in the balance plug in comparison with the number of cells. Not the balance leads. Enter a low a value around half the battery capacity.

My problem battery is a 1500mah 4s battery so i set it to 0 7 a. The balancer only works to bring down the cell or cells that are charging a bit faster then the others. 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. This means the load draws from all cells simultaneously.

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. 5 mω cell 3. Update this worked perfect i have used this batt many times over now with zero issues. 3 mω cell 2.

What seems to have happened is your charger did not cap or limit the charging of one cell in your pack.
