lots of discussions on here, but that topic gives the BRCA advice :thumbs_up:
Mostly be careful how you charge them :D

cheers for the link purpletimbo,now going to have a look,i am using the big muma 4200 and anovak millenium pro charger,charging at 5amps.

should be fine then it is mainly IB4200 and 6 amp then 10 amp repeaking that killed them :thumbs_up:

Sorry Timmy, but your Wrong there mate.


I have Raced and Bashed with IB4200 for 2 Years now and not had 1 Problem !!!!

There Is an Issue with some of the Later Batches, but...

It's also got to do with How you Charge them, What you you Charge them at, What you Use to Charge them, etc etc etc.

If you tell me All your Settings you use, i'll tell you if there Might be any issues.

Obviously No one can be 100% sure, but there's Lots we can do to Help the Cells Not Explode.

Just Don't get too Worried about some of the Scare moungering....


:thumbs_up: :thumbs_up: :thumbs_up:

that would be cool,i am using a novak millenium pro charger set at 5 amps but thats all i know?it does not have a mv setting as i am using nimh2 mode.i would be very gratfull for any help you all could give.cheers again guys.

Cheers Russ, on that link it lists the batch numbers that were at risk, I thought that would be helpful if he was worried, so he could check :thumbs_up:
And it does specify charging settings as well, always helps.

Just so you don't think i've Forgotten you...

I'll come back on later with you definative Answer etc.

Just gotta pop out, so not got time...


:thumbs_up: :thumbs_up: :thumbs_up:

ok no worrie's.i just got back from picking up another xray t1 evo2.also i do discharge the cells on my novak smart tray set at 0.9?dont know if that will help any? :thumbs_up2: guys

Right, ok...

Forget the NiMh setting on your Millenium Pro...

Use the Ni Cad Setting !!!!

This is because you Can set the mv !!!!!

So, set it to as low as it will go. Not sure if it will go down to 3mv, but if it will, set it to that.

Then, i would set your Amps, No Higher than 5A !!!!

This should see you Good and be Safe.

Hope that Helps.

And, Yes, Set you Smart Tray to 0.9v Per Cell


:thumbs_up: :thumbs_up: :thumbs_up:

thats awsome cheers russmini,and every one else for the sound advise to put my mind at ease,your all great, will it take any longer to charge than it did?

No.

It may even be Quicker....

Cause you May have been Overcharging them before...

Theoretically it should take around 40 - 50 Minutes.


:thumbs_up: :thumbs_up: :thumbs_up:

what about my 3300(3packs) as i use these for qualifying and 3600(1pack),4200(2packs)for finals,will i be able to charge them all at the same setting or would i have to change it for each size pack?sorry for constant questions,cheers

You can use the Same Settings for All.

Basically out of what you've got there, the IB's are the Most Troublesome, so those Settings will be Very on the Safe side for the others.

And obviously because of the Lower Capacity, will be Quicker to Charge.


:thumbs_up: :thumbs_up: :thumbs_up:

thank you for all the help and advice you've all been top gentlemen,russmini your top banana.do you have any on road bashes in norfolk or suffolk by any chance?

Unfortunatly Not....

Little bit Too Far for me, and probably most of the others as well (apart from Timmy maybe).

I do plan on coming over that way at some point this year though for a long weekend away.

So if i do... i'll let you know when...


:thumbs_up: :thumbs_up: :thumbs_up:

ye ok that would be good,cheers again.
