What should I do?

[ukglyn]

I have been out today for a quick fly around with a brand new battery that I brought the other day & charged this morning for the first time. Upon getting bacvk & loading my stats into healthy drone I have found I have errors in cell 1 of the battery as the screen grab will show you.

Is this serious & something I should be worried about?

Thanks for any help/advice with this.

send it back pronto

What do the cells look like in the DJI GO app after you charge the battery?

Is it best to return to wheelspin models where I brought it from rather than DJI?

Should I recharge now & have a look?

up to you but personally it would worry me to much to use it

take it back to wheelspin

Yes me to, last thing you need is a faulty battery from new, it obviously isn't going to last too well from that starting point. Just be easier if the local shop would exchange rather than the hassle of sending back to DJI.

I would. I like Healthy Drones, but it could be showing you bogus graphs.

Ok I have put on charge now, what am I looking for in the app that will show up once charged? Am I looking for 1 cell down in charge to the others?

The deviation for cell 1 is less than a 10th of a volt. Most li-pos have to go through a few cycles (5+) to achieve maximum performance & this was the pack's first time out. Personally I'd give it another cycle or two while keeping a close eye on cell 1.

After it's charged, check out the cells in this section of DJI GO:

Each cell should be showing a very similar voltage. Since the battery is brand new, I would expect the voltage to be identical in each cell.

Ok will check once its fully charged up again.

I wouldn't fly with that battery again get a replacement.

Here is a pic of the battery info from the app, strangely its also saying the number of times it has bee charged is 0!

It has to charge at least certain amount or it doesn't count the charge as a cycle. ie If you top off from 80% to full it won't count. Is this your cell reading after you recharged? Cell 1 is looking suspicious if this is fully charged.

Yes this is straight after a full recharge

At this point I would have it exchanged.

Thank you, the shop I purchased from is not open until Tuesday, I will return it to them then & see what they say.

my second battery was same as yours glyn, after flying and charging 3 times cell one settled down and now all the cells are fine. I have done about 15 flights with the battery with no more problems.
