My power wires are the red and black wires running along the board, they’re about 2 feet long each. I should’ve thought about this more before inlaying everything into the board…
It’s super easy to make a capacitor bank. I pulled some capacitors out of a car amp. They are rated at 63v 3300uf and I connected 6 in parallel. That should smooth out most voltage spikes for sure
It will definitely do that. It will make everything better except one thing. Your antispark will need to be TOUGH and/or have a longer ramp-up time. I wonder if @Kug3lis might be able to extend the ramp time in his upcoming king kong antispark so we can use more caps?
I’ve decided to add 3 more 63V 680uf capacitors to each FOCBOX, hopefully this will still be okay for my antispark XT90 and enough to make up for my long power wires.
Does it make a difference if you run your caps closer to your FOCbox or your battery?
I’m gonna have my boxs in the cnc heatsink up top over my tucks. Probably a foot of cable will be needed.
For optimum effectiveness, the capacitor pack should be as close to the esc as possible. The problem with these voltage spikes is the effect they have on the capacitors inside of the ESC. It is those capacitors that additional cap packs are intended to protect.
A couple inches is no big deal, i wouldn’t worry too much about it. Wherever you put it, it will help at least a little… but again, the closer the better
