CAPABILITIES

The Infinity Power peak is a battery cycler, in addition to being a battery charger. The following cycle types can be selected:

• Charge
• Discharge
• Charge followed by Discharge, up to 99 cycles
• Discharge followed by Charge, up to 99 cycles

When multiple cycles are selected, the capacity data for the last 5 cycles can be reviewed.

The cycling capability can be used to 'condition' packs. I have used it on packs that had sat idle for some time, and brand new packs, and in both cases saw the capacity go up with each cycle. It can also be used to make sure that a battery is fully discharged on each cycle.

Initially, my new KR600AE cells took almost exactly 600mAh of charge, but with multiple cycles this has increased to about 660mAh. Note that charge capacity is not discharge capacity, because of less than 100% efficiency of charge.

I have used the Discharge-Charge cycle fully understand the interaction of a battery pack and a BEC motor controller. The process is really quite simple: run the airplane motor until the low voltage cutoff stops the motor. Move the battery to the Infinity Power Peak, set for a discharge current of 0.5A and a cutoff voltage of 6.0V, which is the likely cutoff voltage for the regulator in a BEC. Discharge the battery pack and observe the REMAINING capacity.

I do this after most flights with my KR600AE packs and the Robbe RSC210 relay controller. I have found a 'reserve' capacity of 30 to 60mAh after each flight, which translates to 15-30 minutes of flying time. So now I KNOW what to expect of the battery. Now if I could only find a killer thermal...

SETTINGS

The user can set:

• Charge current, up to 5A
• Discharge current, up to 5A
• Discharge cutoff voltage (total, not per cell)

Setting the cutoff voltage for discharge cycles is an important capability, because you can measure the capacity until the voltage drops to a specific voltage that may be required for proper operation of your system. I have found that the cutoff voltage of so-called 'sport packs' must be set much lower if the pack is to show anything close to the labeled capacity. These are high internal resistance packs, so the voltage drops off more quickly.

MEASUREMENTS

The Infinity will display the following measurements during charge and discharge cycles:

• Input Voltage (car battery or power supply)
• Voltage at TX/RX
• output current
• battery voltage, charge or discharge cycle
• battery current, charge or discharge cycle
• charge cycle capacity (mAh)
• discharge cycle capacity (mAh)
• peak voltage (tracks during charge)
• average voltage (not really explained)
• charge time (seconds)
• discharge time (seconds)
