DPL-8 And Bump Controller - "Lost Data Link"

Have a new DPL-8 with a Bump Controller that was previously used on a PL-8.
Setup works great, but it acts weird at times with strange screen activity and many (most) times after starting a charge on side 2 it will turn red and show 'lost data link'. The screen usually freezes before this and data does not update.

Any ideas?

I just bought a new dual PowerLab 8 touch with integrated bump controller and right now I dislike it.

I get the “lost data link” error message on channel 1 regularly.

It won’t charge my brand new 12v 40 amp hour life field batteries giving me a bad cell count message. Yet the same battery charges fine on a cellpro 10xp as a 4s unbalanced a123 pack.

Maybe I’m new to it but it’s bugging the heck out of me. At this rate I’m going back to the less wonderful no longer in production but works every time thunderpower dual charger.

Just a shot in the dark, but maybe some noise filtering would help?

Can’t see why there should be much noise from a DC battery power supply.

Same thing happened at the field today. 4s 5000 pack gets the lost data link on channel 1 but charged on channel 2. I’ll do some more tests as time permits.

Error 55

Hi Everybody:

I wanted readers of this thread to know that we are aware of the "Lost Data Link" issue in the PowerLab 8 Touch and Dual PowerLab 8 Touch models and we are working diligently to find the best solution at this time. The issue is related to input supply V and/or charge current settings. As a workaround until we have a solution available, you may find that reducing your input supply V to 24VDC or lower may help.

I have the same problem with DPL8T. I hope you can manage it as soon as possible.
Mostly the first channel. Occasionally, it skips data views for example (CellV-CelIR)
A yellow alert screen will appear and then red (code - 55, Lost Data Link)

Has there been any news on this issue. I seem to be getting it allot on my less than year old PL8 dual with separate bump controller. I get it on channel 1 and 2 at the same time. I am powering my charger from a 12 volt deep cycle battery.

The issue reported on the DPL8T is unrelated to the issue you are having with your DPL8. Please send me a private e-mail so we can address your DPL8 problem through warranty service. My address is [email protected]
