when i charge an A123 type battery with tp610c i notice that the amps sometimes doesn't go as high as i've specified so charging takes longer than i expect. i'm charging a 2300Mah Rx battery and i have the charge rate set at 9.2Amps but it never goes that high. right now it takes approx 25min. does this sound right?

Is it a 2S or 3S A123 pack?

Hmmm, you should be good on a 2S up to 10A with the 610C, max. charge voltage is 3.6Vx2 = 7.2V - with 80W max. charge it should able to get to the max. 10A charge. What kind of power supply are you using? What is the highest charge rate that it reaches?

That's a good power supply and should definitely not be the problem. Somethings likely wrong with your charger, the only other possibility I can think of is that the leads or connections on the pack are creating too much resistance, this could cause the charger to reduce current. I would look to see if you are using high gauge charge leads or excessively long, and if there are any bad joints or solder connections. If everything looks okay then you might try contacting the manufacturer/vendor to see if they have any input.
