There is a similar charger here:

http://www.batteryspace.com/smartch...k1cellstandardfemaletamiyaplug38vcut-off.aspx

The main difference appears to be charging cut-off at 3.8V and charging current at 3 amps.

Anybody used one of these?

cool product, and a good price, except that wide a tolerance is more than I would want. If I was going to use it for top balancing I would want something like +/- .1v and repeatability to +/-.01v

Sharon said these chargers are isolated.

I'm going to give them a try.

Yes the charger is isolated.

-------------------

this sounds like a great alternative to a variable bench power supply, which costs closer to $150 for this max amperage. Only issue for me is the accuracy of that max voltage. You indicate in above statement that it might be +/- .05v but then in edit note that it is +/- .5 volt.....

which is it?

Hello Dan,

Sorry for misleading you. But charging voltage is 3.65V , and tolerance is 0.05V so charging voltage range is 3.6V to 3.7V.

I suspect you are still off by 10x.
If the nominal CV=3.65, and tolerance is .5v, you would have results ranging from 3.15-4.15v... which I suspect is not the case.

please check with your technical support and verify the accuracy, repeatability and tolerance of the calibration in these units... and you might want to revise your post to reflect these values.

What we want to know is how close to 3.65v the units are set to a lab quality calibration for the voltage, and how close individual units repeat the same value they are set to every time.

Thanks Dan, Yes tolerance should be 0.05V. norminal voltage is 3.65V
