Lipo Battery Cells Not Balanced

My problem battery is a 1500mah 4s battery so i set it to 0 7 a.

Lipo battery cells not balanced.

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

Why do the packs have to be balanced in the first place. 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. Just over a year now and this battery still performs great. Be sure that you unplug the balance cord.

Update this worked perfect i have used this batt many times over now with zero issues. 3 mω cell 2. Thats why i ask if you have access to another charger. It is crucial that all cells in a lipo battery maintain the same voltage across all cells at all times.

Enter a low a value around half the battery capacity. Just to be sure. 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. Unless it s a single cell lipo in which case you do not need to worry about cell balance.

If the voltages across the cells deviate too much from each other 5mv 10mv the battery can become unstable and dangerous. This means the load draws from all cells simultaneously. For instance from the photo below the balance connector of the three cell battery pack has 4 wires. Suppose we have a 3s 3 cell lipo battery and the measuring the cells independently yields these results.
