I know many of you have read my posts before, Tre's I know is very knowledgeable and always makes very good points. Also yes I do have some motivated self interest here as I am now the contact for anything Pro Trak in the US for the last couple of months or so and will be for a long time.
One thing the Pro trak offers that many of the other chargers do not is upgradeability. Until my recent change to the 30A discharge prototype I had a Pro trak for 7 years which I upgraded to the latest programming every year. Every time there was technology improvement I stayed on the crest of that wave with the same charger, just paid a small fee for the upgrade. Now that I'm in the Pro Trak team, I'm doing the upgrades. Customer Support in the US is no longer an issue.
The new form factor for the 20A discharge version will be available in 3 or 4 weeks with the 30A version a month to 6 weeks after that.
How many chargers do you know that can help you re-match your own cells with individual cell data? (examples available on request).
The new ICS Accesory (tray) works with the pro trak so you can cycle your cells AND tray them down to zero volts individually on a repetative cylce without your intervention other than to set it away with the appropriate information.
The GFX is a great unit and trying to name a charger the "best" is very subjective. I only ask you to please check out the Pro Trak, web site info below and decide which you prefer subjectively.
I apologise to the people who have read my drum banging before, not much of this is new to you, I just want to show people that vanilla is not the only flavor of ice cream.
