It's the 1500w 72v 45a controller

Your best bet is to talk to him directly (e-mail) and tell him what you want.
OR...buy a cheap generic box and have one of the guys here mod it for your specs.
IF YOUR REALLY SERIOUS.."Methods" 100v 100amp controller has yet to be broken (as far as I know)...not cheap...BUT WORKS... ( I made the mistake of giving test rides...CA max amp 216!!!!..still going strong!!(didn't even melt anything :lol: ))
Ya get what ya pay for..............

I was interested in just upgrading a 12 fet version using my own FETs (I already have them), but it appears the e-crazyman's 12 fet (The 1500 watt one) is just about the same "total" price as the one sold by Lyen. I was hoping it'd have crappy FETs in it so I could get it a bit cheaper.

Hi Swbluto,

Do you know if that one has the pads and right firmware needed for custom programming? I understand it won't have the programming "brought out" in the form of a cable or anything, but I can tap the pads myself and use the serial port directly.

yes its the same one as I bought, you have to just solder some wires on to the pads that are there.
Cool. Hey, I think I have an older sucteam 12 fet controller (Like probably 4-5 years old). It appears that it doesn't have the programming pads, but it does have a 24 DIP microcontroller. Would anyone know if this one is programmable and which pins are RX and TX?

So, I just received the controller. I opened it up and I'm looking for a nice set of 6 pads that has some white silkscreen outlining "5V", "GND", "RX","TX" but I'm seeing no such thing. Does anyone know what these pads look like on this particular model? I do see a row of 6 unmarked pads, and as far as I can tell, one is connected to 5V, one is connected to ground, 3 are signal lines and the last one is unknown. It seems like that might possibly be what I'm looking for but it is unmarked...
Also, I'm looking at the mosfets and it looks like they're "75V 75Amp" types. So it looks like they could possibly go upto 72 volts or so in stock form. Too bad that doesn't readily conform to my performance plans, because it looks like changing out the FETs will be some work.

Hi swb,
No pads are not marked :| the info is on this forum somewhere as to which pad is what. Remember that the caps are only rated for 63v. so 60-62v should be your max voltage if using in stock form. The fets are not to bad to change. Even if your not changing the fets out add copper wire to the power traces under the board This helps sink some of the heat from the fets as the stock fet do get rather warm if driven at 70A. Also solder or replace the shunt down to a lot lower value if you are planning on current limiting on anything over 30-40A as the shunt generates some heat aswell.
