my two fans are working simultaneously.. they operate at the same time and they will stop at the same time.. try to rotate the fans individually and feel if the fans are rotating freely if not then maybe that fan is dirty.. try to contact team muchmore

my friends cell master also has the same problem with only one of the fans working. All of a sudden one day it stopped working.

I assume its one of those common problems with a particular brand like say the CDC's backlights fail after a certain period of time with usage.

I just ordered 3 packs of ProMatch IB4200WC cells & need to know the proper charging profile & maintenance needed to get the best from my packs for stock/19T club racing.

I currently have the CTX-CELL MASTER CHARGER V1.0 but I've been racing with GP3700s & was able to get the charging profiles from Nexus Racing's website.

I currently don't have the other MMR battery equipment/accessories. I currently discharge my packs with the Deans 20amp discharger lightbulb set & equalize the cells using an Integy INDI Booster2 Discharger.

Any info would be appreciated before I waste my new packs.

Charge at 6A, 10mV delta peak, and set the capacity to something very high, so it allows the battery to peak instead of capacity cut. Temperature cut should be 48-50°C. Change the delta peak, use heatsink or warming tray to suit the weather conditions.

in the same boat could use a good charge profile

Thanks for the tip. When you mentioned charge @ 6A, 10mV dp & set capacity higher than the mah of the pack, were you referring to Linear charge profile or CTX (Step) charge profile?

Any other things I should do before & after using the packs. I normally race every other Friday @ my local track.

Thanks again for any info or advice on how to charge the packs properly & also on proper maintenance.

i'm charging at 6A, 3mV delta peak, 50deg cutoff, 40deg trigger point for the fans (these are for my 6-cell IB4200WCs). for my older GP3300 i use the same settings except that the delta peak bumped up to 12mV

for prep, i equalize useing a CTXD down to .9V before charging

Are You Using Linear charge profile or CTX (Step) charge profile?

linear. never really bothered with CTX charging as linear does the job for me (5min heats at the local club races)

[Chris08527]

hey guys,
i was just going to ask about settings as my ib4200wc cells have been cap cutting with the setting at 4600 30mv and the packs were only coning off warm not really hot at all

should i set my capp higher??? how high and my mv lower???

thanks
chris

Both. Increase the cap cut to 5000 and reduce delta V to 10mV and use your temp probe with a 48 deg temp cutoff.

[aoizip]

hey chris,

cap off at 5000, delta@10~12mv with temp cut off at 44C.
the temp sensor is off a lot by maybe 6~10 degree C on my unit. so I would use the temp gun on the battery first to to see what temp the charger is seeing. in my case. temp gun is at 120F, charger is only seeing 44C. that is like 4 degree C off.

hope this help.

hey ming
i think changing the settings helped but it is could be better, it now says peak cut insted of cap cut like before, the packs are only coming off like 100 degrees
setting were 5000 10mv charging at 6a
should i put the packs in a tray and get to around 100 degrees and then charge them???
pack was barely warm when coming off the charger but the #'s were way better getting a voltage reading of like 9.1 9.2

[corradopsi]

would keeping the pack in a warming tray after/and or/ during charging help to keep the voltage up? since there are always those days at the track when nothing runs to schedule, i sometimes end up with a pack that has peaked 15-20 minutes before my heat, id rather keep it warm to keep the voltage up, than repeak them all the time.
