100% correct...I'm one of those pylon guys...100A continuous plus in my F5D's...the batteries get about 10 cycles and then I throw them away. Same for the F5B guys. :)

For "getting away with batteries that handle less than 75A", NO, DO NOT DO THIS. If the controller fails due to ripple current we can't cover it under warranty, and you may lose your batteries in the process. Better to buy expensive, buy once.

Is there any way to overcome this issue with the ripple current?

The only way I can think of is more capacitance. But it gets physically difficult to mount more so near where they need to go...

Cool, that's what I thought, but needed to be sure. That works for me then. Thank you Brian.

Hmmm I have just seen your post, will 1p A123 packs work?
