Vision battery !

[Bigvern]

I have a problem with the battery. I have done software upgrades etc: Flew it for 10 min this morning (first flight) battery power went from 90% down to 20% in 10 min !
But it won't recharge it gets to about 37% then charger switches off, any ideas ?
Thanks for your help.

Sadly, sounds like a defective battery - it can happen. Get hold of your dealer and get an exchange.

You could try to reinstall the battery, switch phantom ON, leave it on until the battery is at 3 or 4% then try to recharge it.

Doesn't recharge? Defective battery...

Other thing you can do is connecting Phantom to the Vision Assistant, then click advanced, then battery and it will show the three voltage levels of the three battery cells.

Check them.

Let us know the voltages you read.

I dont know nothing about battery´s but 4 procent is too low. I know my normal Lipo battery´s (not for PV) won´t charge when the voltage has been too low because they can burn during charging and a good charger will prevent charging in that case.
Another thing is that when the battery voltage has been too low, you can have a cell drop out during flight. The PV is a 3S so probably one cell is not working as it should.
Call your dealer on monday.

As you can see reading "current capacity" is one third of the full capacity.

You said battery is completely charged, so, defective battery.

Are you sure that battery is fully charged?

Percentage of charge say 36%...

One of those cells is way out. You have a defective cell, or a defective smart circuit that isn't balancing - one cell is hitting north of 4v and it's shutting down the charge input.

Whatever the cause, email that screenshot to your dealer and ask them when they propose sending you out the replacement battery you require. There are always going to be faulty units in electronic items, and yours is a pretty open-and-shut case thanks to the Vision Assistant readout.
