Power supplies

PowerLab 8 is one of the highest power RC battery maintenance devices available.
Running full power, it can deliver 1344W to batteries during charge. To achieve this,
even on an 8 cell Li battery, it must boost the input voltage. This means the PowerLab 8
may draw up to 1600W from the input power supply.

To take advantage of PowerLab 8’s full power capability, the power source should be
26.35V DC (higher voltage does not improve output power), and capable of delivering a
minimum of 60A to PowerLab 8’s input. Per Ohm’s law, 26.35V x 60A = 1581W.
However, it is generally not advisable to pull 100% of available power from a DC power
supply. Therefore, if you want to attain 1344W of output power to an 8s Li battery, the
power supply should be capable of 1700W or higher for best results.

Likewise, if you don’t need PowerLab 8’s full output power, it can operate from much
lower power sources. Use the steps outlined in

Set Smart Power Management

to con-

figure PowerLab 8 to never exceed the maximum capabilities of your input source(s),
whether DC power supply or Lead Acid battery.
