  • Page 4: About This User's Guide

    About this User’s Guide The text and illustrations in this User’s Guide focus primarily on single channel operation. However, the Dual PowerLab is a dual channel Battery Workstation. Channels 1 and 2 operate identically but completely independent of one another, unless the DPL is set up for Expansion Channel Mode Operation.
  • Page 5: About Dual Powerlab 8X2

    About Dual PowerLab 8x2  Simple to operate: just connect Dual PowerLab 8x2 between a power source and a pack, select a pack-specific preset and start charging, discharging, cycling or monitoring. No jumpers, plugs or dials to set! During Auto Charge, Dual PowerLab 8x2 automatically determines pack capacity and sets optimal current, then dynamically adjusts charge rate as needed.
  • Page 6   takes advantage of the Dual PowerLab 8x2’s high power output. Parallel charging After connecting packs using Safe Parallel Adapters, simply tell Dual PowerLab 8x2 how many packs are attached—charge/discharge rates are automatically divided among the packs.  ...

  • Page 50: Generate A Custom Fuel Table

    Generate a custom fuel table Dual PowerLab 8x2 calculates the fuel level in a battery based on a lookup table for a particular cell manufacturer or chemistry. Even two LiPo batteries from different eras or different brands from the same era can have vastly different voltage-versus-time characteristics during charging.
  • Page 51: Run Multiple Ccs Instances

    You can run multiple instances of CCS on one computer to support both channels of the Dual PowerLab. Here’s how: 1. Connect Channel 1 of the Dual PowerLab 8x2 to the computer using an FUIM3. 2. Launch CCS. Waiting to Start should appear at the top of the CCS window.

    1.5V to activate charging. If an A123 pack is below this voltage, do not try to repair the pack by boosting voltage. Even if you manage to repair the pack, it will not have many cycles left and Dual PowerLab 8x2 will reject it for multiple reasons (as indicated by displayed Safety Codes)....
  • Page 54: How Auto Current Mode Works

    Dual PowerLab 8x2 adjusts charge current at one minute intervals throughout the charge cycle. When charging starts, it takes a short time for Dual PowerLab 8x2 to determine the correct parameters, so it may “hunt” for up to 30 minutes before it settles on the optimum current.
  • Page 55: Estimating Performance Factors

    Estimating performance factors If you don’t have a way to directly measure your propulsion system’s electrical parameters, Dual PowerLab 8x2 enables you to estimate them using before-and-after flight measurements. Note: The calculations outlined below work best when the pack is charged using a custom fuel table.
  • Page 56: Fma Wiring Mode Vs. Xh/Eh Wiring Mode

    PowerLab also supports the popular XH/EH Wiring mode for the balance connector. In the FMA Wiring mode, the Dual PowerLab 8x2 always expects pack + on pin 9 of the PowerLab’s balance port on the front of the unit. When switched to XH/EH mode, the PowerLab will look for pack + on the last wire connected to the battery pack without any empty pins in between.
