Can you give us some recommended setting for the step charging of these cells please? - Just about to try a set from Mr Jolly when he gets backs from his hols

Cheers

Paul

Paul,

The setting found on www.nexusracing.net is really good. Its what I have been using and I know Arun and Kumpol both do their home work with the MMR chargers and such. Arun has been racing a bunch using the IB cells and is fast!!

What advantages does step charging have over linear charging? I still can't figure it out...

Cheers EA just what was needed! Look froward to seeing the benefits of using your cells over the 3300's currently in use!

Josh

As far as I can tell the step charging gives the cells time to cool off during the second phase or step of the charge allowing a higher current to be used - increased punch - but not harming the cells through excessive temp thus increasing the life of the pack.. At least thats my basic understanding...

Paul

We've been testing out the SMC IB3800's, and have been very impressed.
They do get hot quickly, and with the capacity they take a long time to charge at even 6amps. The step charge of the TwoLane charger works great for them, as we charge them at 9amps until about 3500ma, then step it down to 3amps to peak them to full capacity without getting too hot. Is working well.

I've never had an SMC pack and with their 35 amp discharge I'm a little confused with their numbers. What's a good run time and voltage at 35 amps for their IB3800's ?
Thanks.

35 amp to 30 amp add about 60 seconds runtime and .15 for voltage. Going to do some back to back runs with 38's and 37's this week. Been told that the 38's should be better in stock and 19 turn.

Thanks.

For runtime you can do the following. runtime x amp rate divided by amp rate needed. Example: 415 x 35 = 14525 divide by 30 = 484.

Voltage is a bit tricky because it all depends on the IR of the cells. A high IR cell will dropoff more from 30 to 35 than a lower IR cell. On an IB cell a estimation would be .01 - .015. So a 1.165 @ 35 would be around a 1.180 @ 30.

Hope this helps.

Forgot to mention this.

IB3806 395+ , 1.17+

IB3806E 395+ , 1.165+

These are the minimums which we package and can fluctuate from batch to batch. The lastest batches have been better so we have been shipping a bit better voltages.

IB3800 and GP3700 are the same size.

Can anyone offer any insight on the additional maintenance/longevity of the 3800's as compared to the 3700's?

I am hearing that the 3800 may be superior to the 3700, but is not as resilent. Opinions?
