I suggested the time limit, so that the user does not accidentally forget the switched-on hot wire after work. An unattended hot wire might be a fire hazard.

That sounds more like it to me

Hello tuxian,

Thank you for your focus on our products.

Sorry to say that this problem bothers you so much. You can solve this problem by upgrading the firmware into 3.06 version.

But now the upgrading software is under modification, sorry to let you wait some time.

Regards,

Junsi

Hi Junsi, i have never received "Lithium Pre-Charging" menu when charging over-discharge lithium(Manual Page 13), it simply display 'Battery Check, Low Voltage" and refuse to charge.

Thanks.

106B V3.06 just stops

When charging through the mains only, 10A, 4s-A123, LiFe Fast Charge, the 106B just stops in the middle of the charge and displays Vi, Vo, and temperature information. I have it connected to a 75Ah deep cycle battery, freshly charged, no temp probe connected. Any ideas?

Hi Junsi,

when the new software is ready, could you implement this suggestion?
http://www.rcgroups.com/forums/showt...3#post10166033

I also thought again about this:
http://www.rcgroups.com/forums/showt...0#post10125780

Now I have come to the comclusion, that it would be best to change the chemistry first, so that one can change the parameters in the following order:

1) chemistry (LiFe, LiPo, LiIon)
2) current
3) cell count
4) cutoff voltage per cell (only in discharge mode)

Another cool feature I could think of would be the individual parameter memorization based on the chemistry. Right now, the charger only remembers the last parameters in each main menu (Lithium, NiMH, NiCd, etc).
It would be nice, if it could also remember the parameters in the submenus (LiFe, LiPo, LiIon).

One example:
I charge the following packs:
2s LiPo, 1A
3s LiIon, 0.5A
4s LiFe, 10A

The next time I go into the Lithium menu, the charger automatically switches to 1A and 2s when I chose the LiPo chemistry, as these are the last settings I used the LiPo chemistry with. When I chose the LiFe chemistry, the charger automatically switches to 10A and 4s.
It is very likely, that I will need the last settings, which I used with this specific chemistry, again, when I switch to a specific chemistry. It is not very likely, that I want to keep the current and cell count settings, when switching to a different chemistry.
When this feature, where the settings are memorized depending on the specific chemistry, is implemented, this would mean less programming work for the user.

Cheers,

Julian

Hello Junsi,

I already updated to version 3.06.
What is the condition for the charger to stop charging lead acid batteries?

Regarding lipos:

Is there an disadvantage when setting "Li balance ON" to "always" instead of "CV phase"?
What are the benefits when setting "Bal Trickle" to "ON"?

Hello tuxian,

Sorry to say that our reply is not right to your problem. Later, we checked with our engineer again, and got the conclusion that the charger stops when the current reaches 1/10C.

For example, you set the max. current to 10A, so it will stop when the current turns to 1A. You said it was still charging with 7A, that means it was still in the CV period.

Regards,

Junsi

Hello rizky p,

Thank you for your attention to our products.

I just checked with our engineer, the suggestions are as the following:

It will triggle the "pre-chargeing" when the parameters are in the certain condition.

1)LiPo the voltage should be ranged from 3.0 to 2.0 V
2)LiIon the voltage should be ranged from 2.5 to 1.5 V
3)LiFe the voltage should be ranged from 2.0 to 1.0 V

Best wishes,
Junsi

If you want to attempt to recover an LiXx battery that is below the charger's automatic recovery range then charge it at a low rate (eg 0.1C) using NiCd mode until the voltage has reached the recovery range, then stop the cycle and try again using the LiXx mode. Be *very* careful when doing this and do not leave the battery unattended.

It was still charging with about 14,7V and 7A (I set the max. current to 10A).
For a liquid lead battery, this is quite normal. Current will drop very slow in the cv phase, as it is "bubbling out". 2,45V per cell is really quite high. Normally charge voltage should be dropped after reaching 2,45V. iCharge will not do this as far as I know.

You should not charge a solid/gel lead battery with the iCharger, as it will not tolerate 2,45V per cell.

I don't use iCharger to charge lead battery, I just connect it to my 13,8V power supply. This will give much longer life for the lead battery.

But it would be a good idea to talk about perfecting lead battery charging program in iCharger. But only after LiXX is perfect, LiXX ist what is important. Most if not all chargers do a very bad job when charging lead batteries.

Do you know, you can press and hold the increment-button? It goes quite fast that way. But i second this, 10 steps would be enough.

i had two 2s lipo with under 6V, and when tried to charge thse i got error low voltage. So i detached the balance adapter, charged it a little using lipo mode with 1.6A i think (hope it will not die) and then all went smoothly. After charging i discharged it and charged again with balance adapter connected.

What settings are people using and can recommend for charging/balancing?

I noticed the other night when I had it set to 'normal' and 'cv phase' the charger took 1 hour and 9 mins to charge a 4200mah pack. The packs are just getting run in and only put in 1100mah into each of the 4 packs. It seemed to linger around the 41.8-41.9v range for a long time putting in about 0.20A charge rate.

I am now charging my 10s 4200mah packs. Currently I have the balancer set to 'fast' and also balancing on 'always'.

Are these the best settings to have?

I am hoping to get an hour charge time.
