Default Matchers for 3700 cell, fact or fiction what to expect.

Sooner or later 3700's will become legal, so as a cunsumer what can I expect as far as numbers. I do understand that everybody uses a different matching system

1.175-1.185 or 1.191????????????

2. 30-35 discharge amps

So far 1.175+ and 435+ would be safe toay on most of those cells. I hear there is a revision already in the 3700 chemistry coming.

The upper curve is the new GP3700... the lower one is a GP3300... I think GEN1...
Only one german matcher has them at the moment. I donīt know how it is in other countries, but here in Germany you can get them from "HOPF Modelltechnik"...





The new cell on the left....





A test of different cells... Pansan 3600 are IB3600...

looking at that graph
makes you wonder why we need other batterys the way the 33`s perform
the big advantage is with the mod guy`s running 37`s(duration) other then that GP3300 still looks like a very good cell compared with the others

This weekend's racing on carpet at Stockton allowed us to use any 3600/3700 batteries; so, I bought a set of 4 GP3700 cells matched by KC Racing to use in my 12L4 stock car.

The pack ran the race with exceptional punch throughout the 8 minute run; then, still discharged for 233 seconds after that!

I'm impressed.

Default GP3700

I got to really play with a GP3700 pack today.

Only purchased one 4-cell pack to try on my 12th scale so far.

At the final day of the California Carpet Championships, I used it for a practice run (@ 8 AM), the fourth qualifier (@ 11 AM) and the race (@ 3 PM). I was parallel charging a regular 3300 mahr pack just in case.

The pack false peaked multiple times on the first charges...so, I really had to monitor its charging. By the race (its fourth charge) it was accepting 4000 mahr with no problem. On that fourth charge, I was using a high cutoff; but, I'm not sure if that was really necessary

The pack seemed to accept being used like that.

I am pleeeeeeeezed.
