TB47 Electronics

[Jimmy6616]

I’ve managed to acquire a cell pack without the electronics to replace my oldest TB47 with 70 charges. However when I attach my ‘old ‘ electronics board the app is still showing 70 charges where in fact it’s 10?
Is there anything I can do to resolve ?
Thank you in advance

Not without an expensive piece of software.
Why not just keep a manual log of the battery or subtract 60 from any charge count shown electronically?

Might not have an option , if I decide to sell any of them it’s a bit embarrassing to say honest it only has X. If I discharge and recharge will the mah show correctly?

What I have noticed is the mah displayed in the app is the same as the old battery, I.e. it’s following the board , what’s going on ! Doesn’t make sense.

It can’t be that difficult to reset the board, it will work be eprom or something

Battery Re-Calibration might be of interest?

It may be a DJI thing ! But my understanding was the intelligent board would measure the capacity when you charge from empty to full . Now I don’t know the actual capacity of the new cells.

This might also be of interest to address the resetting issue ?

If you don’t mind, where did you get the cell pack?

Thanks, was hoping you had sourced a supplier. Back to research for me.....

The board doesn't know that you performed cell's replacement. Someone mention that it will learn after several cycles how to read the capacity of new cells, but charges count will just grow. However, I wouldn't worry much about it as long as cell's voltage is displayed properly and does not exhibit dangerous drops under stress.

Please let us know if you find one ...

I think if you sell it you are going to have to say that it's a pack soldered to an older board, so you are going to have to explain it anyway
