Does anybody have any follow-up information of the mod Cruzroy did with the cap/top of the TB47? It all appeared to work on the YouTube video, but he never really did a follow-up on the re-calibration to the new battery or what the "final" verdict was. There's a video that appears to be of him flying the mod, but there's nothing but video and music so it's hard to tell if that's what it actually is, and there's really nothing after that on YT that I can find.

I'm having a hard time finding a way to carry on the legacy of my I1 from a battery perspective, but from what I can find, this seems to be the best and most long-term solution or fix. If anybody knows of anything better, I'd love to see some links. Even more information and specifics on the mod Cruzroy did would be appreciated.

Cruzroy's mod was pretty tedious, but once it's done, it appears to really solve the long term battery challenge. Anybody have any feedback?

Why not just ask him?

The thread is here ....


@cruzroy - over to you.

I have and he hasn't responded. I saw a blip somewhere (another RC forum) that alluded to the fact that he may have had some health issues, hence the post here to see if anyone else knew anything I couldn't find posted already.

Thanks for the help.

RETRACTED: SEE FULL POST BELOW

For anybody that's interested, Cruzroy is fine and followed up with me on another board. His mod is still available for anybody that's interested.

Since I'm heavily involved in the issue, would you mind to share the link(s) to Cruzroy? Did he actually flew Inspire 1 with this mod?

Sorry. I just realized I posted this to the wrong thread. I know you've probably already seen it in the other one, but I'm re-posting it here for the historical record in case someone else has the same question at some future date.



There are actually a few. Take a look at all his videos. They're pretty easy to find near the top. This will point you in the right direction.

Yes, I've seen all these videos twice at least, looking for a convincing proof of viability. For whatever reason Cruzroy didn't provided final conclusions, supported by actual videotaped flight of Inspire 1 with modded battery. I remain skeptical, but adoring his attitude of mad scientist...

I saw what appeared to be "the" test flight. Ironically, he never commented during the video at all and never followed up with any details as far as conclusions. I understood he had some health problems so maybe that was a factor? I don't know. I've dropped him messages but he's never responded.

I've ordered connectors myself, and if they're the right ones when they come in, I'm going down a similar same path. My long term goal is to monitor the ports on the Inspire itself and get rid of the proprietary top altogether. I refuse to believe it's used for anything special other than charging and maintenance. It's a low priority project probably for this winter, but I'll keep the forum posted as to my progress and findings. I believe the telemetry provided to and from the Inspire 1 is completely an analog process and everything is provided in a normal balance lead. I'm not sure why anyone would believe any differently. I'm actually amazed somebody hasn't already been down this rabbit hole, but I Can't find any evidence that anyone has.

"I'm actually amazed somebody hasn't already been down this rabbit hole, but I Can't find any evidence that anyone has."

Only true maniacs like Cruzroy or myself may attempt to find ultimate solution to keep Inspire 1 alive for years to come. Not many of us is is left, that's the reason :) ... Keep pushing and - if God will allow - I may challenge you sometime this winter. Meantime check this thread, posted by a longtime contributor to this society. You'll better understand the scale of this endeavour and various obstacles to overcome ...

POLL: Would you purchase a harness to fix TB-47/8 batteries??

That thread is what convinced me it's possible and kinda threw the gauntlet for me. I bought a harness from Rich just because I was having a hard time sourcing the proprietary connector on the TB48 after it swore to me it was dead and I knew better. I've been flying RC for over 30 years. I fly everything from gas giants to turbines and helis. None of this scares me very much. There aren't many things in this hobby I haven't built at least once. :D

I'm also a network security professional and a systems programmer before that out of college, so I get the potential challenges of the handshake between the Inspire and the battery. I just don't think DJI went to that much trouble and encrypted anything. I'm convinced it's an analog proposition and that the circuitry built into the batteries wasn't some conspiracy to sell batteries so much as lessons learned from a support standpoint in an attempt to make the system fool-proof. I'm an adequately armed fool to move forward because I'm convinced the system can be beaten. If my 30 YO trainer is still flyable and hanging up in my shop, I certainly don't intend to retire a $4k quad because some a-hole in communist china tells me I can't have batteries for it anymore. ;)

Cruzroy's got the right idea. I just don't think having to source TB tops and proprietary logic boards is a viable long-term solution. Or necessary. We shall see.

I need to retract the statement regarding Cruzroy's condition. Someone responded to me that I THOUGHT was him and it was NOT. I do not know his condition and he has not responded to my attempts to contact him. Not that he's under any obligation, of course, but he hasn't updated his YT channel in over a year and he used to be fairly active on there. He also hasn't responded on any of the boards very recently. I hope he's OK.

Oh, you're a stubborn nerd :D ! Probably no more stubborn than myself, so let's stay in touch. Good to know you've been talking with Richard, who's involved in early attempts to dissect and cure failing TB batteries. He promised to think about this concept as well ...

Yeah. That's kinda the reason I want to make the I1 a long-term solution too. It's the geek in me. I can't help it. The I2 is an entirely different animal, and more likely than not, it is totally proprietary and encrypted through and through. I just don't think DJI knew how or even cared up until the time the I1 (and v2) came out. The I1 may be one of the best and most affordable (now especially) opportunities to salvage a work-horse style multi for long term use, and I refuse to let something as simple as a darn battery be what stops me.

I'm still beating myself up for not jumping on an I1 V2 that dumped on eBay a week or so ago with SEVEN TB48s and one 47 with an X5 (not RAW but who cares?) for less than $1300. Unbelievable. Guy swore the batteries were numbered and rotated (I asked privately.) and all charged < 25 times. Dangit!

Anyway... I want to pick up an X5 and find a long-term battery solution. I keep thinking the X5 is going to fall off the face of the marketplace price-wise, but it just seems to have hit a sticking point and I can't decide whether to pull the trigger now or not. One thing's for sure. If for nothing else but a spare parts thing, buying it together with a used I1 seems to be the way to go. Hell, I already have the Osmo and all the accessories for the original so there's that. :D

We'll definitely stay in touch. I refuse to lose this war. I don't accept losing the easy ones.

I think I've seen this offer on eBay. Unbelievable indeed, almost to the level of "too good to be true". But it's the symptom of I1 fate ... I have also Inspire 2 in my fleet, even a mighty M200, and I still refuse to retire my trustworthy I1 with X5 or X5R camera. Anyway, here's another opinion about this mad idea, published by one of more influential members of our society just after I start to stir the issue:

#22814

Personally I don't believe DJI packs are that much sensitive to a different charging curvatures as Mad suggests. I had a great success developing field charging devices with various power supplying blocks (both DC-DC step-up converters and AC-DC ps's). None of DJI batteries I'm using refused to accept reasonably adjusted charging current, usually about 1-1.5A above specified. So that shouldn't be a major problem. However, I firmly believe that TB47/48 batteries are employing the same "smart" circuitry and philosophy as later TB50 batteries for Inspire 2. Same encrypted proprietary BS, just different cover ...
