Lipo Battery Cells Not Balanced

Why do the packs have to be balanced in the first place.

Lipo battery cells not balanced.

Thats why i ask if you have access to another charger. 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. 3ω 5ω 4ω 12 mω.

What seems to have happened is your charger did not cap or limit the charging of one cell in your pack. This means the load draws from all cells simultaneously. Be sure that you unplug the balance cord. Just to be sure.

A lipo pack is charged thru the main leads. Unless it s a single cell lipo in which case you do not need to worry about cell balance. My problem battery is a 1500mah 4s battery so i set it to 0 7 a. To find the total internal resistance for the battery pack we would add up the values for the three cells.

Enter a low a value around half the battery capacity. Update this worked perfect i have used this batt many times over now with zero issues. 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. 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.

It is crucial that all cells in a lipo battery maintain the same voltage across all cells at all times. 3 mω cell 2. Just over a year now and this battery still performs great. There s one additional wire that is the negative in the balance plug in comparison with the number of cells.

The balancer only works to bring down the cell or cells that are charging a bit faster then the others.
