<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;"><DIV>I updated the firmware on this charger to take advantaged of A123 capbility.</DIV>
<DIV> </DIV>
<DIV>Now I am getting a frequent output circuit failure error charging my lipos, I have made no change other than this.</DIV>
<DIV> </DIV>
<DIV>Charge lead terminals have all been cleaned etc. I have two chargers and two flight packs that are having the same result.</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>I have reduced my rate from 5A to 4A and at the moment seems to have alleviated the problem. </DIV>
<DIV> </DIV>
<DIV>I will try and go back to the previous firmware to check, wondering if anyone else has experienced this problem. </DIV>

<DIV>Thanks</DIV>
