I`ve ran the Intellect 3600mah cells a few times on the track. They felt just as good as my LRP matched gp3300`s, although the matched pack wasn`t new..
At my pulsar charger I got out a bit over 3900mah on the 10A discharge, with a 6A charge & cut off at 5.4V.
I also tried to deadshort them after the first discharge(after taking them down on a tray first..), and the voltage on the whole pack got about 0.2 higher. The mah dropped down to 3300 though.
The assembled side by side pack is also a few mm. smaller than my gp3300 pack in both length & height.
I don`t really run to much on the tracks now, but the cells seem very good in performance, and specially for the price
