dji mavic pro battery This is a topic that many people are looking for. thetruthaboutdow.org is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, thetruthaboutdow.org would like to introduce to you DJI Mavic Pro battery error fix. Following along are instructions in the video below:
“Right you two quick video on the mavic pro battery issue. It said bad cell cell defective battery broken battery anyway was charging. I was done charging third light up flashing after the charging was complete my experience with lithium cells. When there s two or more cells.
They don t always charged the same and they become unbalanced. Well these smart batteries have a built in chip. Monitoring. The cells.
And if they become 1 10. Of a volt apart from each other it will not let you fly. There is a simple fix cut you an access port front side of the battery. Here here s the measurement from this flat edge here to the other flat edge looks like let me see two inches are so you take push pause whatever take your measurement.
The bottom there you go..
That s where i cut you can cover it up with something maybe 3d printed or just put some paper towel in there it looks pretty well protected and glued. But anyway you get that part cut out this is the balancing for these wires go to the indicator lights here unplug find you a micro plug i got this off of a little micro switch. It was a three pin and just cut the last pin off. I just want to monitor one cell at a time.
I already went this one s been balanced. It was 1 10. Out said i couldn t fly balanced. It out this way and flew just like it was a brand new battery.
These smart chargers are not that smart. The built in smart charters do what they can but they re not the best first cell. I ll call that for point to the lowest point for point. Two eight mmm and we get four point two eight a little high like mine four point two that s the rate of voltage per.
So take this out go to the next..
I always start at the black wire like in red that s your first cell. Then you move to pin though or one pin over that s your second cell. We have another pin over that s your third. So submit that the second cell.
Careful not to touch them pins and short it out push second so call that 427. Very very close like i set up. I ve balanced this one already just showing you how i go through it and it flew just like a brand new battery was in no issues had good flying time. It s just you can t rely 100 on this built in smart charger.
Don t get discouraged with your battery. I ll have to take a piece off this later just no lithium needs to be bounced. When they have more than one cell around last so try not to close i need to do some modifications on my. Flux it s easier to grab 42.
Say i want that one to go up to match the other ones don t go buy a lithium battery charger. Just get you a constant curt board you can get these. I built a little 3d printed box. But inside here is just a buck boost board constant current got it set for two amps.
I said. It s a four point two nine short decide i ll show you the charging amps two amps alright. So you can turn that up if you want but really shouldn t go that high. I m just going high to show you that it actually charged through this port don t ever mess.
The flirty up could be a bad day alright. She s hooked up because there s not much to gain at the voltage. It s that it s showing a very low amp charge. Let s get the real voltage.
There s my real voltage. Here. I thought turn this up you ll see the increase in amperage. I don t know if you can see i don t know i m gonna turn the voltage up and as you see the amperage has went up on the charge.
But that s kind of high on voltage. So you can do that if you want to get real close to what your other cells are reading turn this down see as i turn it down to what the voltage already is the amperage will drop on the charge. So i could probably i could leave that well you set the voltage again without a load okay. It s no longer loaded this is the voltage it ll charge it s not under load.
So i could plug that in leave it on there all night and eventually at that real low amperage. She will come back up it s a two point four point two nine. But that is so close. I m leaving it alone enjoy any questions leave them and i ll ” .
