I think it gives better feed back as to when the pack is fully charged. vs the single rate peak charge. I will attest it does create more heat than a standard peak charge

We do discharge a pack after a run until 5.4 volts and then put em on an equalizer board (Robitronic) before next charge so the pack is completely flat. This takes some time longer for a complete charge.
Iīm using a charge rate of 6 amps mostly and this needs about 42 minutes for a full charge. As I donīt have a GM-Commander for my own I canīt prove this for myself but I was given the 1 hour information from a member of the GM racing-team and I know I can trust him.
One thing is for sure. If the pack is at a higher temperature it will affect not only the way it works at the track but also some things like cutoff point.
But I think the software inside the GM-Commander not only will control the different stages of charging current but it also will control some sort of lockout time during the GMVIS-process. This is absolutely essential as the voltage of the batterypack is dependent on the chargingcurent. Higher current means higher voltage and lower current means lower voltage. The GMVIS-method is changing the current all the time and at any time the current will be reduced. This means the voltage will go down and if there would be no lockout prevention in the software this reduced voltage would mean a fully charged pack to the charger resulting in shuting off but in reality a falsepeak. So maybe this is working better in regard of falsepeaking prevention than the linear charging method but I think this is for the GM-Commander only.
This is also one thing I have heard sometimes - falsepeaking with linearcharging (single rate charg).
At least at the Protral it doesnīt matter what charging method you are choosing, itīs working perfect under all conditions.
But as it seems the GMVIS-method seems to have more punch or rip out of the pack.

There's quite a few guys that hav had the Futaba CDR5000 down here for a while down under. Dual Charging batteries and TX/RX packs....can't go wrong. SO MUCH SEXIER ASWELL!!!!!!!

what did you mean by "dual charging batteies and tx/rx"? can you charge your sub c's and rx pack at the same time?

v12, good thoughts and explaination their. I beleive you are correct on most of your thoughts. however my thoughts are this when charging the charge rate goes up and down this allows for the best of both worlds to happen allowing for good punch and good run times.

I have had/used most everything out there except the new Futaba.
The perfect charger for me would have the following features:
AC/DC
35 Discharge
Charge 2 or more packs
Motor Run
USB PC connection
Dyno option
There are several that are close, but I still have to carry at least 2 chargers.
