Re: Eaton APR48-3G 1.8kW Light Compact Charger PSU

Ok, but it will act at least as CC charger no ? Let's take an example. I have a nominal 48V battery which voltage level is 40V. Eaton is set for 50V max voltage and 10A max current. What will happend when I connect both ? For me battery voltage at first should be around 40V and input current around ...

Re: Eaton APR48-3G 1.8kW Light Compact Charger PSU

To come back to the topic of the thread, I don't really understand why this topic does not interest more people. I might miss something but EATON based chargers are by far the best option (with Flatpack from Eltek) from a quality & power / price point of view. Is there any alternatives in this range...

Re: Eaton APR48-3G 1.8kW Light Compact Charger PSU

After rethinking about it the hardware mod for amp change should be similare as for the voltage.

Just need to find the right track, plug a variable resistor et voilĂ  !

By the way I wonder how was discovered the voltage hardware mod :?:

Re: Kunteng Controller and autocruise

It's in my plan if needed but I was not my first option :)

As I used Eggrider V2 I heard that I will loose many features from the Eggrider such as Road/Off road switch if a change OpenSource firmware :(

But maybe it's wrong ?

Hi everyone, I have a question for you regarding kunteng controller and autocruise function. For my custom ebike projet I used : - G310 from Grin - EggriderV2 display - kunteng controller http://fr.aliexpress.com/i/32819334542.html After few miles, I burned some gears and decided to downgrade the co...

Kunteng Controller : lights always on ?

My Kunteng controller used to have a functional integrated ON/OFF switch that I was controlling using my Eggrider. Now, it is always on, even when the Eggrider is OFF. I made some "surgery" inside the controller to add features but never touch concerning wires except to add a 5V regulator to power m...

Re: Problem with Kunteng Controller / EggriderV2 / Bafang Speedsensor

Problem solved. I changed P3 from "Speed control / PAS Gear Ration" to "Torque / Max power" and then I was able get the speed indication on the EggriderV2 ! Still don't understand why but if it can help some Eggrider/Kunteng owner, it's a solution that worked for me :) By the way thanks for your sup...

Re: Problem with Kunteng Controller / EggriderV2 / Bafang Speedsensor

Sure here are more details : diagram.jpg The problem might come from the controller. I spied the Tx wire from the controller to the display and bit 3 and bit 4 are empty when P2 is not equal to zero. It is consistent with the fact that I never had any speed display with the external or the internal ...

I'm removing the speedo sensor from the G310 from GRIN for 2 reasons : - I want to get the speed of the bike when the motor is off (DH for example) - I want to add a temp sensor to monitor the motor temperature as described here by Justin (https://endless-sphere.com/forums/viewtopic.php?f=2&t=92124&...

The voltage will go up to 58.8V at full charge and I'm not sure that my controller will handle it, can you confirme that ? On the other hand, I'm looking for a 60V controller compatible with Eggride...

I wanna bring this up once again: Any ideas or experience making a resistor-pot mod for changing the output Current ?? like the output voltage mod, just for current. The reason for it would be to make a slow and fast charging switch to the Eaton greets Notger Totally agree with that. It's a really ...
