The difference from the real (measured with multimeter during monitoring so poor balance port connection can not be an issue) cell voltages are 0.05V and 0.08V. Sofar I have been used v3.08 with almost the same issue: 0.05V and 0.05V. All in all if the charger balances the pack to 4.20V/cell, the mentioned cells are overcharged to 4.25V and 4.28V. Is there a way to fix this problem?

Thank you in advance,
Junior

I'm no good at all this, but I have a meter and a 208b: WHERE do I connect the meter to recalibrate? Thanks

For each of the voltages you want to calibrate, you'll need to hook your meter up at that point for the reference. Such as, at each cell, for each of the individual cell readings. Or, if you use longer charging leads, then at the end of them, where you hook to your pack. I did this because I was seeing final LiPo termination voltage over 4.20 (at the cell), so I calibrated the charger to what was being seen at the cell. Now, they're in agreement.

Sorry-I'm a bit dense.

How can you do that if the leads and balance tap are connected to a battery as per the instructions?

When you say "hook up," my meter only has probe type leads: what do I need to "change?"

Thanks!

Question....

Say i power the iCharger 208B with the Mean Well SE-600-24. How many amps will it be able to charge at on 3s? 6s?

With a 24V power supply the 208B will deliver its' full rated 350 watts output. I tested mine at running at 350 watts out put it was drawing 382 watts from the power supply ( not a Maenwell) mine was holding 24.55 volts and delivering 15.5 amps to the charger.

I was charging an 8 cell A123 ,with battery at 28 volts ,12.5Amps. were being delivered to the battery.


Depending on the nonimal voltage you use .

350 watts / 12.6 volts - 27.7 amps. and half of that for a 6S.

Remember not to exceed the recomended charge rate for your LiPolys.

As per iCharger manual, it will be able to output 350W once the input voltage is 17V or more.

350W/12.6V = 27A. The output current is limited to 20A. 3s max current will be 20 A.

For 6s, 350W/25.2V = 13,89A. 13.98A is well below the 20A limit. 6s max current will be 13.89A. In practice it should be a bit higher until you reach the 4.2V cell voltage during the charge process.

But I forgot to mention the 20A max. out put

I am still amazed at how much power this little bitty charger packs and how effecient it is.

So i picked up a 600-24 PSU. Now i need assistance on how to wire a AC Power plug to it. Im assuming you take a standard PC Power Cord and cut the end off and attach the three wires to the spots on the Power Supply. But i am wondering if anyone can clarify this and possibly post a picture of how they did it :-)

About 106B+ question.
I have an 106B+ baught in aug 2009 and updated to V311.
However, when I check the Ri on my LiPo (hextronic 2200 g3 3s pack) then iCharger shows 8 7 8 mOhms with the balance connector connected. Without balance connector ir shows Battrey pack Ri= 75 mOhns.
This is strange, bacuse 8+7+8= 23 mOhms and this differs very much from 75mOhms.
SW bug? Or ?????

When the balance connector is not used, the resistance of the connectors and all the wiring is included. With the balance connector, the wiring and connector to the pack is not measured, just the cells.

In your example, it's indicating that 52 mOhms (75-23) is the resistance of the wiring and connectors from the charger to the battery.
