What happens after balancing a battery?
After balancing, the current of individual cell stabilizes but the current of each cell in the battery system is not the same. Cell #1 with the best health, carries the largest load current output (I out 1 =1.40 A), while Cell #5 is the worst health and carries the smallest current output (I out 5 =1.36 A).
What happens if a battery is connected in series?
When batteries are connected in series, the voltages of the individual batteries add up, resulting in a higher overall voltage. For example, if two 6-volt batteries are connected in series, the total voltage would be 12 volts. Effects of Series Connections on Current In a series connection, the current remains constant throughout the batteries.
