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

I've finally got around to measuring maximum current on HuaTong. So, with 22S I managed to peak about 33A on a steep hill @WOT, and continuously it pulls about 31-32A. I guess that my wiring in some places is still not up to the task od delivering that much current, but those pieces are really short, so even if I put fatter wires in those places I still doubt it would go over 35A peak.
I've opened up the controller and modded first shunt with a lots of solder, so now it peaks around 43A, and acceleration is... insane
. I'm sure there is a reason why it was underrated in stock setup, and those FETs are probably fake, but it still runs barely warm, so there probably is room for modding another shunt .
Oh yes, the biggest cap on the board is heating up a lot on 22S, although it's rated at 100V, it looks like it won't last even on 90V, let alone more.

Well, there wasn't any discoloring, but I've unplugged the controller from the battery, opened it up, and touched the cap almost 10 minutes after being disconected from the battery, and it was still warm although it was 70*F. And controller wasn't used prior to opening, only connected and powered up, so case and FETs were stone cold, except that cap. So can't imagine how hot it was getting there sealed in nicely in controller box, connected to almost 90V.
Anyway, it rated to Chinese 100V, so on real 90V I'm sure it won't last very long.
Maybe other caps were hot, but didn't have time to check that out.

I've used Turnigy Wattmeter. True, it goes only to about 60V, but I've connected negative side (shunt side) inline with controller, and positive side (voltage sensing side) somewhere in the pack. So yes, real-time voltage and wattage is not correct, but current is just fine.

Someone can post some pics of the modded shunt.
I have no idea how to mod it.

Controller came today.. made 9/10/11, definitely some differences about it. For example, the 60/120 wires now have connecters so you can choose to connect or not (no need to solder them together anymore).
Fets inside are indeed 4710 now instead of 4410.. just keeps getting worse, not surprisingly. Board is a bit different too, as has been noted before. Still a good deal though if we can figure out which pad is regen since X is actually wheel lock.

Hi,
I would like kindly to ask anyone who purchase and receive HuaTong controller to:
indicate:
1. place / webpage of purchase
2. Price
3. MCU used inside (big IC)
4. MosFETs used inside
5. Post a detailed picture of the board
Thank you for your understanding and kind cooperation

Darn it, I bought this controller thinking it had regen, but I guess I bought it past the cutoff. I use one of those stupid scooters wired at 72v(48v original) with delta/wye, so regen is really important to me as the damn thing holds a lot of power in its momentum with its excessive weight, and uses a lot of power to get it up to speed in delta. It increases my range by 15-20% I'd say, and on those if you get stuck your screwed (good luck pedalling). I'll post the data requested shortly once I get this thing apart, at least I can enable cruise :?
Where to buy huatong ? i also like to know if there is somebody in china do seller cheaper . Please post it . my last price i bought is USD55.00 with shipping EMS. (4days Only) , by Chatparts.com. just email him or msn him... he will quickly send you one of these controllers. any cheaper..
please show me the link.. im looking is 48v 2000watts, 18fets. i won't buy one. i have 2 of these .

My controller was bought from e-bay, the same supplier as from the link below:
http://www.dhgate.com/72v-1500w-brushless-speed-controller-for/p-ff808081283845f5012848d41bf455fb.html
ebay price was 55usd
DHgate is 37usd.

PeeHell, yes I did. I wrote about it here http://endless-sphere.com/forums/viewtopic.php?f=2&t=29469&start=315#p466831. As you can see, I've now only brought it up to factory values, haven't done any modding afterwards, but there probably is room for improvement .
Pavlik, I bought mine off DHgate, it was $37, it's new design board with 4710 FETs. Pics are available in your thread about this controller.

Anyone try connecting a cycle analyst direct plugin to this controller yet? I am thinking about buying a CA but don't want to spend money on the standalone version if I don't need to. Would it not be possible to calibrate the CA-DP by supplying the controller with a known power supply? Thanks!

If the original only actually put out 30a max, that's already more than I could handle when I first got on the bike :lol:
Well I guess my pretty long wattmeter wiring introduced some voltage and (inevitably) current drop, but I guess it would only peak at 35A even if wiring was fatter.iovaykind said:
Anyway, I can see that shunts is soldered as is, without any modifications, unlike shunt in my Infineon controller, which was "calibrated" with cuts along it's length. My point is: current on HuaTongs could differ wildly as shunts doesn't seem to be calibrated in any way by the factory.
And yes, acceleration is insane on 40A, especially on narrow tires and bike with bad V-brakes
.I'll be home towards the end of the week, so I'll post then. But I've added a lot. I haven't taken it out for a ride just before modding, but wattmeter does notice 10 or so more amps, so that's almost whole kilowatt more power.PeeHell said:
