Brent,
They do seem to only false peak after I discharge and equalize the packs. If I charge them after a heat race or practice session they charge normally and seem to have a higher peak voltage with the same temp. range (120-130deg). Right now the batteries are all new with 6 runs each on them. The MRC 977 is new also. Maybe someone else has experianced this. I'm running IB 3800's from ProMatch.
