Hi all,

I'd be so grateful if someone could help me with the settings for my charger and batteries

I've got an Imax B6 charger and 2x MYSTERY 2800mah 3s 30c Lipo's

These Lipo's-
http://cnmystery.en.made-in-china.co...0mah-30C-.html

The charger is asking for a figure in Amps for charging/discharging/storing so does anyone know what Volts setting I should be using ?

I charge them at 2.8A normally so hope that's correct.

The reason I'm asking is that the last time out they didn't last anywhere near as long as they had before and I need them for a meet this weekend.

Cheers,
Lee

Yes your right.

For charging:

You want to stay at a charge rating of "1c". Unless the bat manuf claims it can handle more.
1c = 100amp/hours

1000mah pack = 1.0amp charge
2800mah pack = 2.8amp charge

Just move the decimal 3 places to whatever mah rating is on the battery you run.

As for discharging, I don't discharge lipos. As far as I know their is no benefit to discharging them. You would only typically discharge nimh/nihc batteries when they have been run a bunch and they accru memory (less runtime) and fully discharging them more or less erases this memory.

The above are correct.
I personally only discharge lipos when they become heavily unbalanced and that is only because my chargers blance lipos by slowly discharging each cell during the charge proccess. With this method it is hard to perfectly balance a pack that has been drained unequally.

As far as storage is concerned I usually set the charger at the packs' nominal voltage, in your case 11.1V.
