Cap banks - the pre-emptive answer

[drwayne]

Hi
2 ways to set up 12S ..

either 12S a side..eg 4 x 6S packs



or 12S shared eg 2 x 6S


Here's a deck mounted set
IMG_0324-1.JPG

Under the deck I place a piece of nylon cutting board ~10mm thick as support for the plugs.
I roughen madly before epoxy in place.
Drill through holes for main plugs + 1/32" for clearance
Insert presoldered plugs from inside hull, tape over top, invert hull and flood plug area with epoxy.
Wait 12+ hrs.
voila'.


The swordfish 240HV have an on/off switch.
The above picture show a deck mounted switch to remote this feature.
use a DPDT micro switch, remember to keep the 2 esc as separate entities at this switch. .

this diag shows wiring beneath the plug

I flood with corrosion X before install and they last for ever ...

Very good!

Did you buy a 250A esc from alibaba? Someone "D. Wayne" bought one pending review. $108 + shipping or slow wait free shipping.

You might get a quicker answer by going back to the begining of this thread, I find this thread contains way more than just an answer to a single question.
Just a suggestion, please don't take it wrong, don't mean to be a smart a**.

Doc, My cap's are coming in at 160 F (71C), should I add more caps?

[drwayne]

They're working hard !
What other temps do you have from that run ?
motor? leads? batts ?
any of those others in poor condition will quickly stress ( overheat ) caps.

extra caps may bot solve the complaint

Midnight down here in AU. will be back in 8 hrs !

[jcald2000]

Everything else is below 125F.

[drwayne]

Everything else is below 125F.

Damn !
Assuming
1. esc is not too small for your setup
2. timing is set right
and
3. motor is not 'free revving without load ' at 100% throttle . ?

yes..these caps need support !
What qty cells and what esc ? .. to offer some quantification of goodies required .

Wow. 313A max.
The caps are hot because the esc is working at 130% its design.

I recommend the set as per this link

Use 63V 470uf as per that circuit.

make the capbank fit inline between esc and batteries as per this attachment.
