I can't get the guys at protrak to email me back. And I really don't want to call since they are in the UK.

Anyone had an luck talking with them via email?

For competition, which charger has more punch and power?
The schulze, gave sufficient punch to my Panas SMH. In fact, we've conduct one objective test with several chargers: Novak Millenium, Schulze Eco Select, Yokomo YZ-720P and a Turbo35 BL.

Every charger peaked one empty Pana SMH (First charge) at 5.0Amps. The results were quite interesting.

Yokomo, gave highest voltage (Compared with a separate DMM), peaking the Panas a 9.78A and being the coolest (42 C).

Schulze were at pace with the Yoko. Peaking a 9.64v and 41 C. With this charger you can charge by Peak and temp charge at the same time, very interesting.

Later was the T35 and the Novak charger.

After this, every pack was discharged at 30A with the discharge function of the T35 and taked note about the seconds and the Av. Voltage, cutting at 6.0v.

Yokomo gave the max. Av. voltage.
Schulze gave the best between discharge time and av. voltage.
T35 gave the best discharge time with a lesser av. voltage.
Novak was the 'worst'.

This test was done with 4 Reedy #624 packs with this characteristics: 1.130v or better (1.132v max), 352 - 353 secs and I/R of the cells with 18 to 20 (My best 4 packs).

With this test I choosed the Schulze. You can go wrong. But a word of caution. Has a feature that cannot be switched off: After peaking, the pack goes into trickle charge mode.

YZ-720P is the older version from Yokomo. the newest charger are BMS and BCS Double.. (both now has Yokomo charge feature)

I think all those three chargers have their own plus and minus if compared. But don't forget you have to compare apple to apple.
I have seen good drivers only using Novak Millenium and won the race.
But if money is no object, I would buy two Schulze.

The charger is key for the 1-3% extra advantage needed at the nationals, worlds. If you drop the bucks for the cells and the charger (I can see my loan officer smiling), then don't have the driving skills, why bother. If you can keep the car between the dots and are top 2 or 3 but just seem to can't beat the local, then you need those pieces.

I watch certain racers that are the torment of all with new stuff week in and week out. But they are also not having to deal with a misses or are related to bill gates. Most of the hot shoes in So Cal will whip you with their year old stuff and tell you the reason is between the ears and the fingers.

Now go buy the damn Schutze and enjoy.

PS I use a Victor Sr. (10 years old) and I have some of the faster cars in class (It aint the charger and it aint just the driver).

IMO, the Millenium, Tekin etc. will charge just as well as the T35, Pro-trak etc. Just the more expensive chargers have more features. They all charge the same, you won't notice a difference there, but you can't run a motor off a Tekin

Some racers experienced a difference in punch and runtime over different chargers. But again at a certain price range the difference is getting very small. I like what Mad Max said about using a 10 year old charger. This really intimidate the others

Just because a pack peaks higher doesn't mean it is better. that usually means it is worse, higher internals.

This can sould a little sillyness, but a higher peak voltage (and, as you said a little higherI/R), many times can signify a complete dump of the battery or finishing the main with the cells weak, but not dumped.

Sometimes is interesting.

A higher peack voltage ususally signifies higher IR. This effectively gives the pack less punch, and less run-time.

Then what can we do if the pack peaks at a higher voltage? Can any of the three chargers 'recondition' them?
