The only reason Ive seen this is to either have long wires or maybe a higher series number in cell count, but when I opened my ownboard ESC today I only saw two little caps … I was wondering what adding an additional one/two would do 
would it give me a little more ability to break when the battery is full? im not sure of how much energy is sent back when breaking in relation to the size of the capacitors
The energy stored in a capacitor is tiny. So it wouldnt help for braking, better off adding more batteries in parallel.
ah ok thank you 
a 10s2p should be safe to ride down a hill if i stop at 41v right? i weigh 160 and the hills arent steep
Additional capacitors will only give you a few extra milliseconds of braking
If you had a BMS that could bleed cells (“balance”) at a few amps or more, you could in theory have unlimited braking but this power would be dissipated in the BMS which means it’d get REALLY hot
Most BMS balance at about 50mA or 0.05 A
You’d need a BMS that could balance at like 5 - 10 A
I understand now 
I dont know much about electricity and the components… might have slept through that unit in physics 
The main reason for the caps on a vesc is to smooth out voltage spikes. On my 12s board I have an extra 6x 3300uf caps to protect the TB vescs I’ve heard of a few failures at 12s and so far so good
you must have been the example i had seed previously cool board!
They will do that but your antispark switch will fail quickly. I’m assuming you’re using a loopkey?

Didnt know they did them in pullet form.
How do you have six of them hooked up? Have a picture handy?
I can’t seem to upload the picture at the moment, check out the build thread that details it below
Are they 63v caps or 100v caps?
I’m pretty sure 63v I pulled them out of an old 2000w audio amp
