Thanks, sounds great!

Because of HW limitations, his non-plus chargers are unable to send charging data to the port.

Some say that is not correct way to calculate effeciency but in my opion it is as it shows how many Ahs are uses per Ahs delivered to battey being charged.
Maybe useful for comparing chargers (input voltage being equal), but voltages needs to be taken into account when calculating efficiencyl; Wh out/Wh in.

Once again. These number are with both (all) chargers using the same power source either my IBM 235 Server PS, or my two 12V deep cycles at very close to same state of charge.

Everyone can measure effeciency any way they desire. To me how much capacity I pull from my field power source to charge X number of cells X times is my holly grail.

See my how big / how many here

Hello Friends,

I use 106b+ since few months and I am very satisfied although would be also useful to make charger settings on PC when connected.
But this is not the reason for this post...

Recently my pack charges like this:

how shall I interpret this awfull drops/peaks just after main phase?
Does it mean the pack is bad or charger (V3.10) gets crazy?
Regards,
gregory

discharge currents?


1010B+.
I have a bunch of A123 cells which I want to check individually before making up a pack. I fully charged the first one to 3.6V @10A.
Then I set a D --> C cycle with an end voltage of 2V @7A and 3.6V at 10A.
However when the discharge cycle started, the current gradually increased to the 7A set, but then flickered between 7A and 1A - after a few minutes it settled at 1.6A. Why ?

First check the settings to see what the max. discharge watts is set to.

Also, have you tried any other cells or tried just discharging at 7A?

Could also be voltage drop from the wiring and/or battery -- did the voltage display read near 2 volts when the current settled out at 1.6 A?

Hi... the discharge max is set to er...max ( 30 watt )
Yes, have tried 3 cells now - all with same result.... and same agin when set to single discharge mode.

Doubt its a volt drop issue - cables are sturdy and only 9" total length.
Voltage display was still at around 2.7V by the time it dropped to 1.6A, so still had a fair way to go.
Latest scenario is now worse...
After fianlly hitting 1.99V on discharge cycle, -and resting for the ten minute cool off period - charging kicked off, and slowly got up to the 9A, and shortly after, I heard 3 beeps and an error message as follows.
"termination at -00095mAh 14m:08 CONNECTION BREAK DOWN.
The cell was still connected.
I repeated it with another 2 cells, and the same thing happened.
I then tried the first cell, on my 106B+ and set up for 4.6A discahrge and charge cycles X2.
All went well, and the pack took in 23110 ma, on the second cycle.
I have just ried updtaing the firmware on the 1010B to ver 3.10 and get "incompatibility message" during upgrade procedure.

How do i discharge a single cell LiPo to 3V? it is always stop at any value above 3V set in the charger. I connect it with balance tap which says 3.1v and in the charger output it says 3V while discharging and that is why it is stop discharging like its disregarding value from balance taps.

You might not be alone on this one tried storage mode for lipo 1.6 amp tried discharge 1.6 amp dosen.t matter what you set at only works at 1.6 amp yet nicad will discharge at 7 amp. also got the( connection break down )had to hit stop button then start button to finish. Before the software up grade could discharge higher with lipo. BOB

208B Calibration Check

I took the charger and a 6 cell pack to work today to check calibration. The reference was a calibrated Fluke 187 meter displaying to 4 decimal places.

Results from cells one to six:

Fluke 208B
4.186 4.18
4.174 4.17
4.185 4.18
4.174 4.17
4.195 4.15
4.192 4.16

21.109 21.11 total voltage

Note that #5 displays 0.05 volts low and #6 displays 0.03 volts low. Positions 7 and 8 were not checked.

Positions 5&6 are out of spec and will result in overcharging.

Junsi, please PM me calibration instructions.

Thanks,
Vince

If balancing port is used during charging, it will care about cell voltages from balancing port and allow the output (pack) voltage to exceed 4.2V/cell. I'm not sure if discharge works in a similar manner. If not it should be implemented this way. Voltages on balance port is far more reliable then pack voltage for a loaded pack.
If it really matters, try setting "discharge reduce" to 10%. Voltage difference should be less at the end. Not healthy for a Lipo though ...

Junsi...I see you are online right now
Please advise on my issues posted earlier re the 1010B error message, and also, could you please advise the correct firmwar update bin file version for my 1010B. Its marked 1010B on the case, but I had an early development model which was upgraded to 1010B+ by yourselves.
Upon start up, my version says

ver 3.08 AAA
1010B+ (TEST)

Thanks.
