72v 1500W 40A Hua Tong CA08 XM06AD_P04.1 controller

[cwah]

Yes, I can try.

Can I wire the x or xs pad anywhere there is the "GND" written?

Ps: no idea what are the 4710 feets are lol

[PeeHell]

Yes, any free pad where it is written gnd. Let us know what happen.
Maybe we will finally enable every function of this chep controller someday....

[PeeHell]

By the way, don't forget to run trough your brake lever...
While you have it openned for testing, you could try both pad.
The 4710 fets are your transistors (the 15 black "things" bolted to the heatsink). Some are better than others and chinese just put the least expensive of the day in those huatong controllers.

[wesnewell]

Ok, finally opened the controller.

On this side we can see the "x pad" without anything:
Not sure how to make sense of this for regen or ebrake lol

And here lies the problem. That is NOT the CA08 XM06AD_P04.1 controller PCB. It is a later model. This is the CA08 XM06AD_P04.1 controller PCB.

If your board is not exactly like this one, then the connections are probably totally different. Take questions about your controller to another thread, as you are just confusing yourself and everyone else.

Shall I also try to test the x and xs pad?

Created another thread for that.

[Beachcruzer]

Anybody seen these lately for less than $47 landed in the USA? Best I've found today: http://www.aliexpress.com/item/72V-1500W-Brushless-Speed-Controller-for-Electric-Bikes-High-Quality-OT100/287758466.html

[cohberg]

7 cents less than that and only 5 cents off your target lol.

[Beachcruzer]

Haha, thanks. I'm gonna hold out for that nickel, dammit.

Seriously though, are the 30-something dollar ones long gone?

[flez1966]

Damn...

When i found this thread I thought I had found the answers!

my controller is a chip/pcb by bolee and then its populated with fets elsewhere and sold, seems to match 90% of whats in this thread but.........

on the bench its running fine, take it out and after 10-15 seconds it trips out.. this 10-15 seconds gets shorter and shorter till its like only 3-5 seconds, and I get 7 flashes.....

oh well.....

Check your battery voltage to make sure it is not sagging under load to low voltage cut off.

It blew a bank of fets, i think one may have been iffy and eventually went short, now trying to find ''cheap and genuine'' 4110's in the uk.... about $8 each is best at the minute....

Buy a controller of zenid on this forum he is in the uk same as us it will work out cheaper, i have had one off him for testing never blew it up yet and they had the better fets in quick delivery

hi

just checking it's ok to leave these controllers connected 24/7 and turn them on/off with the ignition wire/switch...

no power drain etc... ??

[kentlim26]

I think it advice better don't. Just add a power switch Box. Just off it !. By just going to connect power all the way to controller, I think the controller will have some Heat. can try for few hours and see , if the controller stay hot or not. as for me, i will not do that. So far, i have never read anyone says " I put my power to the controller 24/7.. will this really damage the caps silently. ? or will it really blow? Must see who has done that ?

[flez1966]

both mine are powered 24/7, and i just use the ignition wire.

do they drain the batter this way, yes, about like guessing 0.05% per night..... they only thing powered is the smoothing caps and the mosfets which leak so tiny amounts i cant measure it on my meter

[knighty]

cool, thanks

AFAIK, all controllers use a small amount of power when left connected to the battery. They're just like any other electronic device you have in the house. Left plugged in they draw a minimal amount of power. I always disconnect one side when I get off the bike for more than a few minutes. It doesn't use much, but will ruin your battery by draining it to 0V over time.

[flez1966]

Yes I think it will, but like i said, its so small it can hardly be measured, and it will add up say over a few weeks, I use mine almost daily and have had no problems, the wife uses hers daily in the week and often leaves it all weekend, not yet seen an issue with batteries being flat etc.

maybe some controllers take more power in 'standby' than others? best way to find out is try it and see, with a full charge leave it for a few hours and check it, and keep checking every few hours, if the pack starts to go down you know you cant leave it

If caps are damaged it will be with the inrush or large outflow of current, not while connected for long periods of time.

[kentlim26]

thanks. i solve the in rush current by going throu a resistor 10watt 100ohm and you will see spark, noise will be entire gone. 48v ~ 65v it works. i have also try 98v throu a 10watt 200ohm, i think the spark will be gone, but this i haven't find out yet. some will use mosfets and build a circuit to the controller, soft switch. i hope you can try to find this out regarding about this 10watts 100ohm, or 200ohm, and there i build inside a switch Box no2. is a main power into the controller = hence No more in rush current

98V and I think you will make popcorn!

[kentlim26]

i really did that , Half eye closed.. so i really run this volt 98v go thro this switch A, thro a 10watts resistor 100 ohm. i had even thought this will give me a LOUD spark POK or sound more like a gun fire" .. but to my surprise, Oh.. NO Sound and just a tiny spark, from power to the controller.I had only scare myself In my box has two switches, A and B. so some current has gone to the caps, i On my switch B . I have recently bought this greentime controller for some fun to run near 100v. 16cells + 10cells lipos, all fresh charge, volts was also tested. I want to find out the Number ? how fast ? not fast enough, my goal to reach at least 80km/h, but done only 74.5km/h. i think the 10cells lipos are not giving enough amps, is just only 5amps

16cells of lifepo4 + 6cells of lipos 10amps , i can get 70km/h .
16cells of lifepo4 + 9 or 10cells of lipos 10amps ? speed ? i will know once i order some more lipos

[Gordo]

There is nothing wrong with learning by doing. Much more valuable than my armchair comments. As long as you are not too far from home when the plasma attack happens. good luck and please keep us informed.
Thanks

[flez1966]

i really did that , Half eye closed..

Have you opened this controller and seen what part number is on the mosfets, and what voltage caps its fitted with?
