Battery info for a converted dh project

[laurent helfer]

Hello,
I m currently building a dh bike with a 2000w motor/controller...

I need to build a custom battery in two parts for weight distribution.

Is this best to take two 7s4p (24v) battery in serie or two 14s2p in parralelle. So that s same final specs but I need to know for the charging Wich will be better and less harmfully. I also need the most powerfully setup...Wich one will give the most final wattage... I think this is related to the bms, this is a 45a on the 14s2p do you think if I put two on parralel I ll have 90a? How about the first 2x24v serie config?

Please help me !!!
Thank to you all!

Wich will be better and less harmfully.

Better in which way?
Less harmful in which way?

I also need the most powerfully setup

Doesn't matter. The total voltage in both cases will be 48 V. The total capacity will be 56 cells × capacity/cell. Therefore the total available power and energy are the same.

I think this is related to the bms, this is a 45a on the 14s2p do you think if I put two on parralel I ll have 90a?

Afaik youi cannot simply put 2 bms in parallel. Their operations will interfere.
