Default HELP NEEDED! charging battery's

I need to charge my 6800mAh Ni-MH 7.4v batterys on my new IMAX B6AC and can't work it out.
I need to know how. I can't work out the cells or whatever. like it gets to where i have to put in 0.0A but i don't know becuase i can't get past 5.0A its as high as it will go.

Shady

According to the specs for the IMAX B6AC, 5.0 amps is the max she will produce. I assume you are wanting at least to charge the 6800 mah Mi-MH at 1C or 6.8 amps. Sorry but that can't be done due to the 5.0 amp limit on your charger. 1/2C would be just fine on those batts though so go ahead and set it at 3.4 amps.

Cheers...RD

Spec. IMAX B6AC
Input Voltage: 11~18v
Circuit power: Max Charge: 50W / Max Discharge: 5W
Charge Current Range: .1~5.0A
Discharge current range: .1~1.0A
Ni-MH/NiCd cells: 1~15
Li-ion/Poly cells: 1~6
Pb battery voltage: 2~20v
Weight: 580g
Dimensions: 133x87x33mm

Thank you very much you have been a big help, would I do it twice at 3.4 amps? or just once and move on to the next battery?

Once will be sufficient. The 3.4 amps is simply the current you are charging at. Set your charger to the type battery (Ni-MH), cell count (2) and charge rate or current (3.4 amps). The current will begin at 3.4 and drop off as the battery starts nearing capacity. Connect your balancer plug to the charger also and each cell will stay balanced with the other. Hope this helps...RD

Do you not mean to set it at 6 cells? A 7.2volt NiMh is a 6 cell battery.

Correct. I meant to say" cell count (6)".

Thx!
