HAs anyone had any issues installing the IB3600/IB3800 cells in the Losi JrXs when using the individual shrink wrap and an aluminum tray?

Thanks

Okay, I'm still having a problem with half my pack over heating. I've been racing for a long time and am no ROOKIE. So what the %#[email protected] is causing this??

They are Promatch TEAM packs, I have torn the packs down resoldered them and all...

It's like the pack isn't cutting off on the first 3 cells and the other cells are still charging...

I'm using a Pulsar Comp 2 I've dropped the cut off to 10 for the pack.

Did I get BUM batts.??

Are you equalizing the cells before you recharge? Just a hunch.

Tks Anthony. So Cato is the brother of Derek and the owner of SR Batteries? The two brothers are so active in HK R/C. I can see their name in most HK Races. Wonder why Andy Lam has slow down in R/C??

i thought the lrp only went down to 5mv cutoff? isn't that too hot to charge the 3800's? i've always used 5mv on the pulsar for gp packs and felt it got them pretty warm...

another question... i gotta friend with a novak millineum charger, is 3mv low enough for 3800's or is that going to get them too hot as well?

thanks for the info, this thread is very helpful!

ringrat, if you use extra shrink wrap with 3600 and 3800's it's going to lengthen your pack by like .040 and you are likely going to have to dremel out the plastic part in the rear of the car to get them to fit.

The only real way to know if your packs are getting to the right temp is with a temp gun,chargers are diffrent so you will have to borrow a buddies temp gun if you don't have one to set your charger to the right temp 125-135 degrees is what you're after,mine peak right at 130 degree's this is on a gfx set at .02 dropback charging at 6 amps.

That is how I came to the 10MV per pack that my charger is set at. 5 out of 10 charges this will happen. The first 3 will keep charging almost like the line lock out is on, and there is no peak detect set. While the others are right at 125* the first 3 are at 150+ and still trying to charge.

If I don't shut the charger down they start venting...etc etc

Check the voltage on each cell and see how close they are.

The biggest spread is: 1.218 to 1.215 in a pack.

I can honestly say I've never had this problem with my GP cells.

Are these the #'s on the labels? measure the cells with a volt meter say at their EQ point they should all be at .09 or what ever your EQ point is then measure it again at their peak to see what it is then.
