Modding 24fet Lyen 4110 Controller

[Ugrd]

Ive been using my EB324 24fet controller I got from Lyen for a while now and its amazing coupled with my 5403. Recently it has died due to fet failure, so I thought why not just mod the whole thing to a bit more (because electric power is addicting)

This thread will serve as my build thread with tons of pictures to help other modders in the future.

I want to be able to run a 32s Lifepo4 battery (Full charge: 113.6v Nominal: 102.4v) at 150amp bat and 250amp phase.
Currently I have it running at 150amp bat and 250amp phase at 72v.

Im looking at doing the following mods:
- 4110 to 4115 replacement for higher voltage - http://www.digikey.com/product-detail/en/IRFB4115PBF/IRFB4115PBF-ND/2096589
- Top board cap replacement for higher voltage - Can someone recommend me a cap replacement for the voltage I want to run? Currently there are 8 Rubycon 100v 1000uf caps on the board. Will I have to change the smaller caps on the board to something else to?
- 4 Snubber cap additions to the bottom on +/- power rails: Kemet PHE426HD7100JR06L2 - http://www.digikey.com/product-detail/en/PHE426HD7100JR06L2/399-5961-ND/2704615 Ive seen zombiess run these exact caps before, and im pretty sure they will work in this application too, if you have a better cap choice please tell me
- 8 guage wire for battery and phase wires - Hobbyking silicon wire
- Waterproof connections and sealing - Basically a smaller version of the waterproof connections you see on trailer connections
- Temp probe attached to one of the heatsinks - http://www.ebay.com/itm/171247030109

I know there might be some other things to change out on the board to get above 100v on this controller besides the fets and caps, but I couldn't find any info for that, if someone could show me what and where that would be awesome

Bottom, excuse the not cleaned solder at the bottom from when I replaced the fets before

Is there any reason you want the LED display?
I have a bunch of LCD thermometers and they run forever off the coin cells and are very cheap, e.g. http://www.ebay.com/itm/321646733607

I already bought them, and I got the LEDs so I can read it at night, and they are powered off 12v, so I can just hook it into the 12v converter.

OK, I'm facing the same decision now - I have a LYEN 12FET with 4 blown IRFB4110 FETs. I'm running 24s, 96V off the charger.
So the question is "just" repair or upgrade? Have you made some progress yet?

for 96v hot ideally you will need higher voltage fets also if the caps are rated at 100v look for some thing with a higher voltage
