So I am still struggling to find a battery that can output at the Amps that I need it to.
The motor claims it needs 45A continuous, lets add say 20A to that for the BOS and maybe 5A more for the controller to run. That means we need a battery capable for giving us 70A continuous. This is somewhat a problem as it seems most comercially available batteries only really can do 50ACC.
I will probably need a custom battery then, and that means either I have to learn how to build a battery - or I hire someone else to build a battery for me. Sadly all of the battery builders I can find online never reply to my emails, so I am somewhat unsure what to do now.
I have found these high capacity cells, which claim up to 3C (i.e. they can discharge themselves at three times their capacity - in this case 120A CC). Im not sure if I would need to BMS these together or not - as I can specify high/low voltage with my controller. That would, however mean adjusting my wiring diagram to have it charge through my controller somehow.....
