Discharge current not correct when balance port not connected.

[TBAMax]

Discharger seems to use only Id min for discharging when balance port is not connected for single cell Lipo mode. Normal discharging current is not used at all, and all discharging is done with miminum current. Do not know if this is a bug or a feature. I would assume it to be safe to discharge with full current even when balance port is not connected(specially for single cell).

Also noticed that NiCd discharging current seems to be not correct when doing D>C format. Seems to be using minimum current setting instead of normal current setting for discharge.
