Kelly KHB 12151

[bobzilla]

hi guys.... I recently installed a controller Kelly KHB 12151 on my bike, Cromotor V1 and L-33s 3p nanotech iPo ... I knew that this version is not very powerful but still looking for the reliability that I had with the previous controller (Lyen24 fet ), I had changed in such a way that gave peak current to 300A and 120 continues .. unfortunately does not accept such currents and broke 2 times in 2 months
the decision of Kelly? ... painful! .. I have always considered my Lyen 24 a monster of current "uncontrolled"! and the fun was insured but without the reliability hoped
applause at Kelly for various functions encoded error, you can not instantly identify the problem ... but what about the power I was really disappointed though it was installed the new firmware the unit can not deliver more than 42A peak and few kW at the wheel
a friend of mine with the same firmware at least managed to pull out at least 160A and 10KW ....
the batteries and motor are ok ... the program of Kelly is set to maximum power ..... the idle speed is good (141km / h) I can not find a solution to the problem ... if I knew the result would have taken a Greentime controller at $ 40 which was perhaps even better!
What do you think of my description? Is this normal?

cazzarola...almeno uno straccio di risposta potevate darmelo

Hi,

I'm a bit surprise that you didn't talk with Kelly about this problem may be they have a new firmware for your or at least a hint.

Be sure to use the correct version of the program when you try to program your Kelly controller otherwise you can experiment issues like this.

This summer I was using another laptop with an incorrect version of the programing software and it take time to realise that I’m using the wrong version for my controller after that everything is working fine.

You claim that you use 33S of Lipo =138.6 Volt (Over volt protection) this is a bit too high for maximum 136 Volt controller, did you try 32S or 30S with this controller and see how it goes?

Good day!

hello and thank you for your reply, I want to point out that the load 33s Li-Po to 4.12 V for area.The a maximum charge of 135.9 V and the controller is not by abnormalities
I must say that I asked the firmware file not directly to Kelly but a friend of mine who has the same model, the doubt, however, that his KHB 12151 Kelly has the serial number: 13020220 ..... my: 130.020.370, now i do not know if the difference of the last 3 numbers is only the difference of the pieces produced since our 2 models were acquired at a distance of 2 months
The fact is that while the performance of the controller of my friend have changed so drastically improved my Kelly did not suffer any increase .. it remained exactly as before .... and it is already much that the new fw did not block the microprocessor
you're right: I think now that probably will contact the provider to ask questions
last: while my friends with Cromotor and Kelly KBL / KHB have noise-vibration typical at the start, my combination is not pruduce nothing as they have my mates ... smooth without any noise goes away .... I do not know if it a good thing or not

an overview of what the B.R. hides behind one of the sides

last one (in that picture, to be wired) a dc-dc converter 12> 24V that gets power from 2 LiPo 3s 3A in series, is used to supply the best of the opto Kelly

proof made ​​a huge difference in performance and bad delivery in relation to the previous 12V

do not ask me why: huh: I do not know give you an answer

and I did not even know how to give my friends with similar controllers: D have done tests from 12 to 30V without notice any difference ..

from the first round of the Kelly proved somewhat disappointing with a peak current of 36A: woot :: woot :: woot: I started to make tests on evidence: first, the new firmware (improved, however, very little) ....... . the battery switches 400A ......... instead of TORQUE SPEED mode where the current jumps in plain nuts (type Lyen hoping for more reliability) and reading here on the forum to 99 put everything that was set to 100 of course .........: ALL!

strangely speed gives me more torque at low engine torque of: (and what is even more remarkable after 70/80 will form a light hole and then explode into a lunge crazy: gas firm begins to accelerate on its own tear her wrists. taste .... that ..... the skill lies in the stop in time
