Although i dont know that particular charger, changing the number of cells shouldnt be the way to go. For lower temp u should use lower Delta value. Just my .02 cents

I got to break in a couple packs last night and they were solid throughout. I did have 2200 mAh after my 4 minute run which shows how much capacity these batteries have for stock racing.

I know what you are saying but if you look at Atushi Haras set up for his charger for the Reedy Race USA he was charging at 5cell on the step charge.I know he was using GP3700 but i thought id just give it a go with the IB3800 and i hafto say the cells felt very fast and came of the charger between 35 deg C and 45 deg C.Also a couple of other differant drivers here in the UK have also tried it with the same results.

What a great weekend for IB3800s. At there very first major race the IB3800s proved to be very competitive and popular at the IIC Vegas race with over 50% of the A main drivers choosing IB3800's.

Danny,

You poor Americans are unlucky it took so long to legalise the IB cells. We have been racing these cells for months with wins in just about every major race here. These cells are awesome.

I will try it this weekend at my club race. I'm still in the "dark ages" with my trusty ole Integy 16X9 V5. I cannot set my peak detect less than .3 mv and my cells do get warmer than I would like. I will give the 5 cell a try and see what gives. Let you know how it works Sunday night or Monday.

You should bring them down to .90 per cell at a high amp rate 30/35 amps and then leave them alone until the next time you use them. Just before charging them place on a resistor try until the lights go out which should only take 1 minute or so then start charging the pack. For long time storage 2-3 weeks or more put 500 seconds of charge back into the packs.
Hi Danny,
Have you tried equalizing them down to .10 per cell? I am currently using a Novak Smart Tray to equalize my cells. Will it make any difference interms of performance if I do this or I will just damage my cells? Btw, what is the usual peak voltage of the IB3600 and IB3800? What should be the numbers so that I'll know if my cells are still ok. I've hit 9.3V peak in a couple of packs and some packs had gone up to 9.5V peak (all peaks are on IB3600s). Thank you very much.

Sonny

It's very hard to say what the peak voltage should be because it all depends on the ambient temperature, airflow and the particular charger.

For now the best way to treat IB cells is to discharge them down to 5.40(.90 per cell) after your run. Leave them alone until the next time you use them then place them on a tray that brings them down fast with resistors like the Integy 0-30 for 1 -2 minutes prior to charging them up.

If you plan on not using them for 2-3 weeks place 500 seconds of charge back in them prior to storage.

Hope this helps.

Thank you. I am currently using a Much More CTX Cell Master Charger.

Maybe others with this charger can tell you what they get for peak voltage. It has been my experience that some chargers read differently than others. The packs temperature will also have an impact on the PV and if your charging out doors or somewhere that airflow will come accross the pack will also affect it.

Danny/SMC: Would the voltage be alot different to matchers having 0.85 to 0.90 cutoff?
