Team Much-More cell master v1

[Alex_kipper]

Yes the charger is suppose to do that, when the voltage goes up, the amps should go down.

Someone else suggest me to get a new supply that they go up 15V and see how this will help?

this happens w/ any charger doing like 8 cells or a 3 cell lipo, you have to have like 14-15 volts to keep the amps up, othwerwise th charger gets confused when you only have 12v input and the battery (output)is showing 12.1
this happens to me when i do my tx packs and dont have the juice cranked up

Quick question...

.02 delta peak for the ENTIRE pack equivalents to what in our CTX charger??? I thought I understood, but now I'm confused. Is our deltaV adjustment by pack or by cell?

Thanks.

Delta peak value setting on CTX Cell Master:
03 means 3mV (0.003V).
You can set the value from 03 to 99mV/pack
or
you can set Zero Delta Peak at 00 (0mV).

Hope this helps.

I've changed the melodies and tones to my tastes but....

How can you turn that anoying start up tone off?

I can't see it anywhere in the manual.

Thanks,

Anyone???

Thanks Kumpol, please allow me to throw out an example and for you to check on my math...

So if I need a pack to peak @ .02V, that means I'll be setting the charger to 20??? Is my math (thinking) correct?

thanks,
Dom

Yup, but the thing about the cell master is it's a super linear charge, so the actual peakl detect is a little different. I basically adjust delta peak to get the correct final charging temp.

So since we are in the same region, about the same temperature, use same IB's, run the same car.... use the same charger.... what's your starting point Sush!?

Hi Sushi boy

I think, final charging temp is affected by outside temp.

The starting temp is very important.

Low starting temp(cold battery) makes low final chrging temp.

Low final chrging temp means that loose punch.

Much More Battery Warming Tray is warmer that can heat up your battery

before charging.

Too high delta peak makes over charge that reduce battery`s number of life cycle.

Correct charging method give you more punch and long life of your battery.


Sorry for my poor english.

Thank you for your advises.

I will look into a new supply with 15V...... Not too many charger can withstand high input though....

[badboy]

Hi guys. What settings do you use for Tamiya 2400 Nicd stick packs? Thanks...

[yellow15]

so what is a good temperature when the charging is finished?
slightly warm? 40degree C +? or ??

that's for the GP3300 or 3700..

A setting of 20 would be the equivalent of .02V on another charger. But, as Sushi Boy pointed out, the super linear current of the CM requires different (lower) delta peak settings to be set. In fact, these settings are lower than other chargers even offer!
05-06 (.005V-.006V) is a good starting point for IB cells.

Refer here for some more info and starting points for charging IB cells.

It has been said that NiCDs perform best with a linear charge. The charging rate is entirely up to you...just don't melt your connectors .

As a general rule:
Lower charging rate=more run-time, less power
Higher charging rate=more power, less run-time

NiCD's also like higher delta peak settings. I would start with an 09 or 10 setting.

Additionally, a stick pack has more resistance in its connections. This can cause a false peak, especially in combination with lower delta peak settings, so you will probably want to set a long-lockout for the first 10-15 minutes of charge.

Arun you coming up this weekend still?

I don't personally have much experience with using flex charging, but it is basically a non-linear form of charging that de-crystalizes cells during charge. It was most commonly utilized with NiCDs before the arrival of NiMHs.

You can envision it as something like this:
charge -> charge -> charge -> quick discharge -> charge -> charge -> charge -> quick discharge

This is one form of flex charging. Most chargers thatcan flex have the option of increasing or decreasing the intensity. This is accomplished in the setup menu for each profile on the cell master...Fn (no flex), F1, F2, F3, etc

The best way to get performance out of your NiMH batts (today, at least), though, is either with a linear or CTX charge. Some who have flex charged their NiMH batts have reported a decrease in power.

A lot of us are now starting to basically flex-discharge our batteries with the Spintec Battery Manager and Trinity Dyna-Pulse dischargers (and upcoming CTX-D from MuchMore ). These units will pulse/flex-discharge your packs to condition them and keep them good.

I'm sure flex charging will make a big comeback some day...just like dead-shorting did .
