Hi:

Obviously that PSU is terribly inadequate for the PL8, but I guess you already realize that. Did you follow the guidelines in the user guide and set the input current limit on the PL8? If...

Good catch. This is most likely the issue. I didn't notice customer said he had homemade balance cables before. If O.P. can post a photo of the pack wired up and connected to the PL, we...

Great explantion! I concur! The charge is considered "DONE" when the charge current drops to the charge termination current level defined in the preset. Generally this is C/20 which means (Capacity /...

Hi:

Glad you got something going. The PowerLab 6 can only do 2A on a non-balanced charge as you've discovered. For safety reasons, we don't let the user go above that using the non-balanced...

Sorry, forgive my ignorance. How many cells are in the pack that you are trying to charge without balancing that is giving you the cell count error?

Yes, when charging LiPo in parallel, you may have different capacity batteries, but you MUST maintain the same cell count.

Hi:

This is absolutely normal. The cell voltages always sag after charge ends. They will settle down closer to 4.200V soon after you remove the pack from the PL. This extra 8 mV will not damage...

FYI, you also have to start the charge with a pack that is no greater than about 70% state of charge. Easiest if you just make sure the pack just came out of your model after a flight.

For fastest results:

1) Use the LiPo Generic High Power preset

3) Manual rate should be 2.2AH * 2C = 4.4A * 6 (packs) = 26.4A (provided your...

Sounds like a thermistor is defective on the PCB assy.
