nitecore i2 charger problem with second channel...

Batteries and Chargers Chargers
1

Hello guys,
greeting from Cyprus!!

I have a fairly new (about 6-8 months old) notecore intelicharger i2 v2 and it appears to have a problem with the second channel (when looking at the charger from the left)… it seems tha it terminates charging at 3,92V when the other channel terminates at 4,25V…

when I switch the batteries the first channel charges the battery fine so it is not a battery problem…

so basically i have to switch channels when charging finishes to have both batteries charged at the same state…

it also does not occure every time i use the charger…

what is going wrong with thw charger??

Itsa broke, buy a new one if it's out of warranty.

Mine terminates early too. Sometimes I can get it to finish if I restart it enough times.

After some time i figured out that all of my unprotected panasonic 2900mah where changing fine and also one set of sanyos which are unprotected…

the problem occures when my protected sanyos or panasonics are being charged.

so, i removed the pcb on all of my batts and now they are charging fine…

i dont know why is this happening, probably bad pcbs on some batts.

also because i use a dr. J nanjg 105c with low voltage warning at 3.0V and quality batteries i assume that i don’t really need ptotected cells…

If the “good” channel is terminating at 4.25v, which is on the high side, I think that the “bad” channel is going to a high enough voltage to sometimes trip the over voltage protection of a cell.

i have checked it several times, both channels terminate at 4,25V!
dont know what was wrong but now everything seems to works fine…
