I have used the Tekin in the CS mode. But I am using a temp gun with it. So I never let the charger peak outin CS mode. It can really over charge.

Default Use fans during charging

Hi Danny,

You said the ideal temp. for IB3800 is around 140-150F. Do you have any suggestion about what temp. should I set my charger to activate the cooling fans.

Thx

For those interested in some of the newest batch of IB3800.....

I just got my load in from SMC (matched by SMC!)....

I lowered ALL prices and even put up some new factory team 1.2x cells at 35 amps!

When we match cells on a TM4 the cells will peak at 140-145 using a 6 amp charge. As a pack we reccomend .02 peak detect which may get the pack to peak at a bit lower temperature. From what we have seen so far there is no need to get the IB's to hot so anything 130 - 145 should be fine.

You shouldn't have any fans blowing on a pack while it's charging. Just set the peak detect on your charger that will give you the proper temperature range.

I charged my ib's for the first time last weekend using the pitbull x3 and it was flawless. .02 cutoff got the cells just the right temp and shut off. I also charged some 3300's at .05 cutoff and they peaked much cooler than with my pulsar yet the pitbull put the same mah's and voltage into the packs just cooler... have no idea except that maybe the pulsars are less accurate on cutoff... but have zero to back that up... i've been happy with pulsars but am quickly falling for the pitbull x3

I have been a proud owner of CE chargers since the mid 80's. I'm sure there are many good chargers out there but the CE ones work real well and the customer service is second to none.

Danny, I mentioned this on another thread and I'm not sure what your opinion is but my peak detect setting varies greatly depending on the ambient temperature of the room and my charge rate. I will set it anywhere from 0.01-0.05 to get the cells to peak at 135 degrees. I have a temp gun at my side always and consider it a must for electric racing these days. In the summer I may be at 0.01 but the winter (tracks around here don't like to put the heat on) I'll be up around 0.05. In the end all I care about is what the cells peak at temp wise. We all always get the "what peak detect" question but the above is what I recommend to all my cutomers. Let me know your thoughts...

Yes ambient temperature is important and I reccomend that the serious racers get a temp gun to monitor the temp and try to find the ideal peak detect for the conditions or charger they use.

If you race at a track where it's cool then using a higher peak detect is reccomended. When you race outdoors and it's windy you should also keep your packs out of the airflow to get a proper charge.

Yeah, temp guns are pretty cheap these days. I use an infrared one that cost me $30...

After reading this post I ordered a few 3800 batteries from the Brood website. Am I right in assuming that what I ordered are originally SMC 35 amp matched batteries. Just want to make sure because I've had the best luck with SMC batteries.

Thanks

Slow.

You are the lucky one. That's really a good deal. I got mine SMC Racyer Packs only have 1.78 volt...

Yes we do the matching for BrOOd and use the same process as our SMC packs.

We communicate with IB frequently and in our talks with them we told them that the voltage curve is more important than capacity. They told us they would work on it but we never expected them to be able to pick up .02 in such a short time. Guess they have a great R&D team and they really want to make the best RC race cell.
