iCharger 306B Storage mode

[shagnat]

Need help with storage mode with 306B iCharger.

Trying to put my LiPos in 'storage' mode. The charger puts them at 3.75v instead of the customary 3.85 volts.

I cannot figure out how to change the amount of voltage to 3.85 in storage mode.

PLEASE help ASAP. Otherwise I'll ruin my batteries as some are getting close to the infamous 3.0v/cell.

TIA

Storage voltage is a range really. I think you are just fine with 3.75v. But perhaps others will pipe in... but is it adjustable at all? I don't know.

I believe it's only adjustable in discharge mode = %

Page 16 of the PDF manual I have shows how. There is more on the page including pictures but this may help.

“Storage” charge/discharge a Lithium battery

The nominal target storage voltage depends on the type of Lithium
battery: 3.75V/cell for Lilo, 3.85V/cell for LiPo and 3.3V/cell for LiFe. If at the start the battery voltage exceeds

the target storage voltage the program will start to discharge rather than charge.

Storage of Lithium battery. The left side of the first line set the type of battery
(LiPo, Lilo or LiFe). The value on the left side of second line sets the
charge/discharge current and the value on the right side of second line sets
the cell count and voltage of the battery pack. After setting the current and
voltage, press

Start/Enter for more than 3 seconds to start the next
process.

Charge current: 0.05 – 30A, Voltage: 1 – 6 series


Medic...out!

I have the same problem with my iCharger 306B. I have set my discharge voltage to 3.85V, but in Storage mode it stops a 3.90-3.92. If I switch to Discharge mode it still quits without taking a mAh out of the battery.

Then I hook the battery to a cheaper charger in Storage mode and it takes 500 mAh and reduces voltage to 3.85.

Any clues?

Make sure the Discharge Reduce setting is enabled. This works like the Constant Voltage phase of an actual charge, gradually tapers down the current until it's XX% of the original current. Set the current percentage to 10%, with Discharge Reduce enabled, and see what happens.

If Discharge Reduce is disabled, as soon as a cell touches 3.85V, it immediately stops the process.

A battery at 3.75V per cell should stay at that for a very long time. If your battery is dropping to 3.0 volts per cell while sitting then something is wrong.

I have left lipo's over the winter and their voltage did not drop at all.

I just use the discharge function/setting instead of storage mode w/ the voltage set at 3.85v.
