I just rescued my TB47 thanks to the harness showed in the video and to Rich’s advice. My battery had a defective cell, I could charge it up to 30-40%, it would last for 4-5 min. up in the air. Rich’s harness allowed me to balance the cells. It is basically the only way to rescue it by levelling the charge gaps. Flying with a battery which is not 100% is just too dangerous.
Hello, the 1.25mm is pretty close. The problem I found was that DJI specifications are slightly different causing a problem with the the fit. I was using DJI donor connectors for the best results. In my opinion this enabled DJI more control over their products. Best of luck to you
@@RichJ53 thanks a lot for your quick response. I do not think these are proprietary. Even with the numbers of batteries DJI makes, that would not be worth it. I was in charge of industrial design at a very large global electronics maker, I think these are standard JST board-to-wire connectors, I just do not know which ones. There are so many. But still thanks a lot for taking the time to respond, I really appreciate it!
@@rogiervdheide you’re welcome.. you are probably right about proprietary items or special connectors. I just didn’t have much luck buying them in small quantities or that fit into the DJI socket. They also control the end of life of their products by making it difficult to get aftermarket parts to work. Hope you have success with your project. Rich
Hi Drew, sorry I no longer have the special DJI sockets to make the custom harnesses. The 7 pin jst connectors are hard to come by. Most of the ones I had were made from bad TB47-48 packs. Wish I could do more. Sad seeing the end of life for the inspire 1 drones. They are still an awesome platform. Rich
@@DJteamster the guys at progressive are awesome. The real problem is getting the socket and pins with ability to crimp these tiny wires. You might make some jumpers and just clip on to the cell that’s high and discharge it by hand. It’s harder but doable.
Sorry no links to the DJI socket connector. You might find one on eBay the cones close to fitting. The socket plugs I use on my custom harness are from old DJI dead batteries which fit perfectly. I can make a few more of these custom harness kits. I charge $45 and this includes the custom harness, plus power cables. Add Shipping USPS these are made to order. These are very challenging to make and to get it right. I get a lot of people asking for the cable but apparently they change their minds at the cost. Rich
@@mljjones2210 sorry, I no longer have any of the special socket connectors. It would be a lot of work and some battery experience, you could pop off the top and try to discharge the high cell using manual jumpers. It would be difficult but doable. The tiny 7 pin jst connector is very hard to find unfortunately I would have to buy multi thousand of them to place a order from the factory. Not worth it for the occasional requests, plus the inspire 1 is at the end of life because DJI stopped making any parts.
Fantastic work here. I have one completely dead battery that I could strip and make the balance cable myself for my other batteries. Have a tb47 with 24 charges and cell 3 is -0.25 so will not charge above 70%. Would you have a wiring diagram for the balance cable?
Hi Aaron. Thank you for the kind words. Please keep In mind that LiPo batteries don’t like be under the 3.3v per cell or low charge for long periods of time. This and other factors can damage the battery beyond repair however each case should be considered fully. As the internal resistance increases it becomes less likely to accept a full charge. At that point you need to decide if the battery can be fixed. Send me a PM on the DJI forum and I will try to help. I do not have a wiring diagram available at this time. The balance socket can be soldered to a std balance cable such as my video. You can use a volt meter to find the polarity. Take a lot of care for safety reasons. :)
Yes I can still provide one of these harness kits. There are several chargers that can work fine ISDT T8, iCharger X8 or X6 but all of these require a power supply.
Hi Yes, I have enough material for a few more harnesses. The socket plugs are removed from bad batteries. I make these custom harness kits to order Provide me your email address for more info
@@RichJ53 Thanks for your prompt reply. I sent you a PM on DJI forum with my email address. I’m also looking for a good but not too expensive balance charger to fix some TB47/48. If you have and any recommendations and instruction I would be most grateful. Everything that uses mains would need to be 230V compatible.
Hi I will check it thanks. Regarding a charger: it needed to have a dedicated balance only circuit. Not a balance charging mode. Only a few chargers have this (icharger-x6)($110) this is the least expensive charger with this feature.
As long as all the cells are over 3v and they haven’t discharged to zero. If they do, it will damage LiPo cells and they can’t be trusted to come back or the internal resistance becomes to high for them to take a charge.

Hi Stuart, the custom harness is a very nice tool to have to manage your Inspire 1 batteries. But as you know there is no way to guarantee of success in each case. So far most users have been able to fix their batteries, but a few have not. If a cell has been below 3.3v or drained to zero, that's normally a death sentence.

Hi Rich, this video is fantastic - thank you for your hard work and time! Do you still have the special plug adapter for sale? I sent a PM on the DJI forum. Thanks!
Hi, the battery capacity is monitored by the DJI intelligent circuit. I believe this was designed to provide you feedback as the battery is cycled through its normal life. 200 cycles being the end of life. Most people do not get that many but some might get even more. So, the DJI Assistant development software, years ago would let us make some changes to the hardware but it was eventually removed and locked the users out. So based on what I understand, you would not be able to change the capacity in the FW of the battery (locked out) Maybe someone else reading this could inform us more? Rich
Dear Sir, I want to try to balance my TB47, is this still possible with the products you advice? Or are there better solutions at this moment? I never used such a balancer, does it need to be programmed, or are there easy presets for people who are not too technical? Thanks for your help!!
Hi, I do not believe there are new solutions regarding the T47 / 48 DJI batteries. DJI would you ratter buy new replacements instead of fix the old ones. You do need to have some basic understanding of the LiPo battery chargers and how to use them for safety reasons. This is a good way to fix or manage batteries that still have good cells. This will not really help you with batteries that have been sitting around with zero power or dead cells. Hope this helps youRich
Unfortunately DJI stopped delivering these batteries (no replacement available). So I have a choice: look for a solution or end of my hobby ☺️. The batteries have a low usage, but the cells are not balanced 🥴 I have no idea how to fix the unbalance without your solution... I know the support had ended, but I don’t want to stop flying right now ☺️.
So, if you want to recover your batteries with a little learning. most new LiPo chargers are pretty easy to use. I can still make one of my special harnesses for you and provide all the supporting information to get you going. You need to PM me on the DJI forum group or post your email address. Let me know if you are interested.
Hi, great news, just wanted to comment for others reading this post that might have this same questions.Both the TB 47 & 48 use HV Lipo cells rated at 4.3v per cell when fully charged. I recommend discharging or balancing mode on your charger to get all the cells even. Do not go below 3.3v per cell when discharging. Then slowly charge at about 0.5 amps (this will take a long time) either to storage levels at 3.85v per cell or to normal lipo settings of 4.2v per cell. You can always charge the rest of the way using the stock DJI charger to get up to 4.3v (or full charge) you can verify this by connecting to the DJI Go App with the battery installed in the Inspire 1 and powered up.Rich
And I also want to follow up that after using Rich's cable to balance my cells with my standard run-of-the-mill B6 charger, the DJI charger charged and topped it off just fine. There's still a minor difference in cell 3 so something's going on with that guy that I'm going to have to watch, but it charges just fine. In the interest of full disclosure. I have a LOT of multis, and most of them sit for long periods without even having their cases opened. This Inspire probably hadn't been flown in over a year, so I know that's a lot of the reason. So Rich's cable saved me from myself. Thanks, Rich! BTW, I ordered the X8. :)

I cannot confirm they are the correct ones until they get here. You can email me if you would like, I can send you the link to them. brandon@farsarizona.com

Okay 👍
I have the same problem. I need the plug adaptor. how do I order it from you?

Great job Rich! Need your skills to fix one of my I2 batts that failed after 18 charges.
Thank you Lars.... I wish we had a way to access the Inspire 2 battery balance port. Unfortunately DJI has bonded the I2 battery case together. I don't see any way to disassemble this without breaking it. Rich
The whole thing is too expensive but it would be great if big drone suppliers have it
You are right, chargers and testing tools can be costly. But so are these batteries are very expensive too. Thanks for watchingplease hit a like or subscribe for my future updatesRich
just use a motor as a load, to drain the higher voltage cells to the lower voltage level... until all cells are at the same level
