This is an off-road golf cart build that's gotten WAY out of hand.
I'm going LiFePo4, but past that simple statement I am lost as to which cells to buy.
It's a 9KW, 12HP permanent magnet AC motor. The inverter is contained in the 840 amp.....yep, 840.....controller. That's overkill, for sure, but I'm thinking it might draw 500-600 amps at maximum load. That's a guess on my part.
Will be running it at 72V.
My plan is 24S 3.2V prismatic cells, and would like 200ah minimum. I'm thinking I need 3C maximum discharge rating, but would like input on that.
Any recommendations as to the best cells to buy and from whom? With all this juice, are there any with heavier terminals than I'm seeing? Is bus bar size (thickness) an issue?
What about a BMS to handle all this?
What is a shunt, and do I need one?
If anyone has any advice as to what holes I'm about to fall into, please shout out.
Many thanks, and Cheers!
