There is no cheali-charger FW for the Imax B6 80W Clone Yet ?

There is no cheali-charger FW for the Imax B6 80W Clone Yet ? How do I know if my charger is a 80W it looks the same as the normal Imax b6 it says 80W in the box dono if they just print it because how can this 6A charger give 80W ???

There are builds for B6 80W with Nuvoton MCU. You have to check what MCU charger use. It can even be blank and thus not supported. Quite a lottery. 80W versions are not much different from 50W ones. There will be some changes in power parts, not much more.

I have no problem at all removing mine to see what MCU it has but how do i check if its a Nuvonton MCU when I see it as I read on the forums that the Chipi is just blank 

[diggit]

AFAIK Atmega and Nuvoton has label. If there is blank chip, it is something unknown and not supported. Not 100% sure about it though.

Well it is no lable :( will i brick the charger even if i give it a try?

I ve the same, looks like the processor is z51... Not compatible with cheali BUT perhaps IT could Be replaced by atmega32 (seen on A post), i ordered 2 to Try to répare mine (20days from china)

You were unlucky here. :(

This is not Atmega32, crystal is on different pins. You can look through this mailing list, there are some threads about this topic.

Replacement should be doable, but those MCUs has completely different pinout. You'll have to track where current traces go and wire it up pin by pin to Atmega. I gave up after approx. 13 pins connected.

I dont think this is a 80w a imax b680w has to have 4 mosfets on the back if im not wrong ? This is just a another 50w imax b6 is my guess

Nop I think they just put the 5V regulator on-top on this design.

Hi!

I have also the same 3 FET design and i am also qurious about its' unknown processors' type and if it is flashabe. I have found a russian topic about this type but i can not read it unfortunately... Heree it is : https://www.drive2.ru/c/2797964/

By the way, on its box and manual it is written that it is 80W but on the site where i have ordered it was witten 50W... so it is another question gentleman!

- they don't know what kind of chip is that.
