The Eagle CDC v6B pushes the cells harder.
The good thing is, that the cells comes of very punchy, great for stock racing.
The bad thing, is the pack temperature is quite high, at charge termination.
Have you guys actually measured the cut off temperature?
At 26 degrees Celsius (79F) ambient temperature, my GP3300 peaks at 60 deg. C (F140). This is with 6 amps charge rate and 3 mV pr. cell cut off.
With NiCd, the charger do it really good, no heat problems.
With AA 2300, the charger seems to have a problem with the cut off - I've seen an example where the charger charged for 7 hours....
Yet, I'm happy with my CDC, as long as you know the limitations of this charger and take proper precautions, it's great...
