Look at the first picture on the first message of the thread to see the correct terminals to connect the balancer leads. Make sure the cells are balanced. Then if you are still getting an error, you could try to reset the BMS circuit. If you look at the same picture you will notice a pad marked...

The discharge balancer I have (hobbyking hk-010) has been around a long time. There are certainly other alternatives. I prefer to use a discharge balancer rather than a balance charger because balance chargers only balance when the cell is at full charge (and most don't charge HVLipo cells cells...

Check out the thread Balance plug for Mavic pack. There are a lot of Mavic packs doing this now. It's simply a cell imbalance that comes with age. There is likely a LOT of good life left in the pack yet. Some people are reporting this problem with only a half dozen cycles on the pack. It seems...

Wow, this is becoming an epidemic! A friend called me over the weekend and told me he was getting this battery cell broken error on his Mavic Pro (refurb) just bought last year. He only had one battery and was dead in the water. I told him I could fix it and he dropped it off Sunday afternoon. I...

When you get the broken battery cell error (cell imbalance), the Mavic will not fly with that battery. Full discharge and recharge does NOT help. In fact, it can damage the battery further. It can be fixed, but requires a bit of work. Not recommended for someone without a very steady hand and...

This is an increasingly common problem with Mavic Pro batteries. Full discharging/recharging does NOT help. In fact, it can make the problem worse. I've fixed two of my own Mavic packs and one for a friend. It does require a bit of work. See this thread that I posted last year... Balance plug...

They can be fixed, but it takes a bit of work. See this thread. https://mavicpilots.com/threads/balance-plug-for-mavic-pack.34806/ I have more Mavic Pro batteries than I need at present, so not really interested in buying anymore.

I'm revisiting this thread because I just started flying my Mavic Pro again this spring. Guess what? I have another Mavic pack with the dreaded battery error and a low cell - which refuses to fly :( This time I got the battery pack apart more easily with basically Zero cosmetic damage. The key...

I like the idea, but I seriously doubt that DJI would even consider it. The vast majority of people would prefer to get everything they need to fly in one package. Being able to use a separate charger is great of those of us who already have one, but I'd bet we are in a tiny minority...

Correct, a properly functioning LiPo charger won't damage it. But charging the battery cells directly (not through the BMS) will screw up the calibration. The battery management circuit monitors current and time (mAh) when the battery is being charged and discharged through it. That is how it...

It sounds like a great idea except for one thing... When you charge the battery cells directly, rather than charging through the BMS (battery management system), the BMS has no measure of how much charge has been put into the battery by the balance charger. This will screw up the battery...

Opening the pack without some cosmetic damage is very difficult. I have used super glue debonder and "glue-buster" on other drone smart batteries (not Mavic) and it does make it much easier to get the cases apart. Unfortunately, both of them will attack the plastic and will crack and weaken it...

I bought a Mavic about a month ago and the online mission planning feature of the Litchi Mission Hub was a big factor in deciding to add a Mavic to my drone fleet. The POI's are a great feature that I've used on mission planners for other drones. But the new fly relative to ground feature of the...

I own two complete 3DR Solo setups, and just bought a Mavic Pro with 4 batteries and a lot of extras on eBay a few weeks ago. My experiences so far... I fly the Mavic in Sport mode much of the time - this disables the collision avoidance. I do this because the collision avoidance causes the...

I've cycled the battery 4 times now without the balance charger. No need - using just the DJI charger is faster so long as the cells stay in balance. DJI would not have to include a balance lead on the battery if they simply had a more effective built-in balancer. A really good smart battery...
