Lipo charging issues??

[mindless]

Hey guys was at the track last night and was having a problem when charging wondering if i could get some help.

I have a newer SPC 2 cell 5000mah battery and a Thunder AC6 and when i go to charger it the main screen will read 8.40 and only charge at .1 then when i switch to the balance screen it show the battery at 3.75 per cell. Checked it with a friends cell checker and it matches. I dont want to have something be unsafe so i stopped using it.

Now I also have a duratrax 230 which charges fine but doesnt balance. I had considered getting an external balancer to work with this but would be easier to just have the AC6 work properly.

Not sure what i should do at this moment now maybe there is an update for the AC6 with the program that i dont know about but yea any help would be great thanks guys.
