    280AH cells not charging above 3.3v?

    Thank you all! This was partially an issue with the bus bars and I believe partially the charge current setting. After charging the cells individually, I was able to get them up to 3.55 (when the charger was set to 3.6 - this is where the 10% charge end current setting is kicking in). I've...

    280AH cells not charging above 3.3v?

    Correct, I am top balancing in parallel. The charger can deliver up to 30 amps and I set it to 20A, but I was only getting 3.6A at the end before it told me it was full. At o At one point, it was able to deliver about 9A, but it gradually decreased. Charge voltage is 3.6V The charge leads...

    280AH cells not charging above 3.3v?

    Thanks Bob, very well could be. I set the termination voltage to 3.6v and the charger was showing a charge voltage of 3.55 - 3.6, but the DVM i have never read teh terminals being above 3.33 on the terminals of the cells

    280AH cells not charging above 3.3v?

    Hey guys, I recently received a set of 4 varicore 280AH LiFePO4 cells, but after charging with an icharger 306b, it keeps telling me the batter is full at 3.3V. What am I doing wrong here? Are these cells grade B and hence not going up to 3.6V? Thank you in advance!
