REDOX alpha v2: working with B6 original firmware

[det szalat]

Hello, 

first of all - thank you guys for this firmware - great job!

I want to add another device to list of chargers working with cheali-charger firmware. Photo in attachment.

Brand: Redox

Model: alpha v2

Redox is popular brand of RC LiPo's, chargers and accesories in Poland. I think this is the cheapest IMAX B6 "exact" copy (same pcb layout, processor, elements, etc.) available in Poland for 80-90 PLN=~23-25 USD.

One difference is branding name that shows up after powering the charger.

Redox alpha v2 looks like an exact copy of "genuine" imax B6, at least isp pins and elements visible on photo of original B6:

ISP pinout is identical as above in "original B6", I've managed to program cheali-charger-imaxB6-original_1.00-20150310_atmega32.hex with USBASP programmer.

Calibration, temperature sensor works.

Cheali charger works very well. So far I have only one complaint - it is annoying: selecting values is difficult in some places - i.e. calibrating charge/discharge current. Long pressing up/down works with few speeds. Last "step" of speed is extremely fast and it is nearly impossible to stop pushing key in right time. AFAIR this problem is not occuring i.e. when selecting capacity mAh and max current of particular battery. What do you think about it?

Regards

Michał
