NiMH battery in parallel or series

[rakesh1987]

I would like to know the advantages and disadvantages of connecting NiMH battery in parallel and series concerned about charging also

20 cells in total, which is best topology , please specify with reasons:

2 parallel of 10 cells in series (OR) 20 cells in series.

thanks in advance.

If you Connect the battery in series battery voltage multiple with same current. i.e.

if you have Battery voltage = 6 V, Current = 1 A.

After serious Connection you getting 3 batteries in series. V=18 V. I= 1A.



If you Connect the battery in parallel battery Current multiple with same current. i.e.

if you have Battery voltage = 6 V, Current = 1 A.

After parallel Connection you getting 3 batteries in parallel. V=6 V. I= 3 A.


I hope its helps you

iam not looking for the total voltage and capacity, any other concerns in paralleling and series configuration

Don't use parallel connections, you will reduce the life of the batteries. Batteries with low voltage will take excessive charge and batteries with high voltage will discharge at too high a current.

if you connect battery in series you have to add a BMS ( battery management system), if you will not use a BMS you will have an imbalance between cell and you will have one cell charged and the other not charged
