[FSE] need a help.

[Bishoy Medhat]

Hello, I knew that you were participated at formula student competition ,
so I think you can help me in these problem. I will be so glad if you help
me. Thanks in advance.

I want to give energy from batteries to electric vehicle motor which
specifications are (600 Volt,75 Ampere,8000Watthour)
So first I found High Power Polymer Li-Ion Battery: 51.8 Volt, 20 Ah
(9759156-5C, 1036 Wh, 40A Rate) Rechargeable Battery Pack If I use this
pack , I will use 8000/1036=7.72(proximity 8 batteries), 600/51.8=11.58
(proximity 12 batteries) , so by these number of batteries I adjust volt
and watthour but to adjust ampere i must make another 12 batteries parallel
to the last 12 batteries. Finally I have 24 batteries but now I have a big
problem each battery pack weight 6080 gram. totally I will have
6080*24=145.92 Kg. but I saw that it is a very big weight . did it make a
logic weight or there is another solution?????
