Battery Mod Info

Greg Huntoon · Oct 30, 2020

To anyone interested, I found the UBRT (Universal Battery Repair Tool) site (in Russian). Via the link below, Google Translate does a really good job of translating the site into English. I'm so far impressed with the amount of information especially when it comes to desoldering a main pack from a BMS and in what order. Also, fuse replacement and unsealing the BMS. There are useful insights like the Phantom 3, Phantom 4, and Mavic batteries.

Google Translate

Red_Label_DJI - A special version of the license to restore batteries Phantom-3, Phantom-4, Mavic, Spark, Ronin, Inspire, Agras (and others) from DJI

Allows the user to access programming of bq30z55, bq9003, bq40z307, bq78350, bq34z100 chips.

A Red Label DJI license costs a flat 200 USD.

Well, that stinks, it does look like they take Paypal so you'd have some protection for a possible refund. The info seems good though. Probably due to the limited ability to transact purchases in Russia.

On a plus note, I just bought 2 brand new TB48's off eBay for 349.95. I confirmed with the seller that there were indeed 2. Yup, that's 175ea. Not a bad day after all.

Here's an update. While I thought I got a good deal for 2 TB48's, it looks like I received 1 TB48 and 1 TB47, both are completely dead. Fortunately, the seller apologized and said they would issue a full refund. I still have to get the refund but as of last night, I was pretty sure I was out my $349.95., now I'm cautiously optimistic. The batteries are packed up and ready for return. Man, that seemed like such a great deal too...

It's risky to buy those baterries as they are not produced from long ago. It's good you'll get your money back.
Three months ago I purchased 2 tb48 from our local dji dealer and they told me those batteries are on the shelf from years so to be aware and I cannot return them to the shop but to dji's service if they are faulty. They came out to be in great condition but when I check their serials found that they were produced back in 2016 [emoji44] so far a lot of flights on them and there is just slight deviation in one of the cells on both of them. Unfortunatelly the local seller doesn't have any more.

What stinks is DJI is still selling refurbed Inspire 1's. They should also still be selling batteries.

That sounds pretty promising, However I'd ,ove to get a couple of those modes batteries instead, my problem is I had a hack on facebook and I closed it, now to open it FB is asking for a copy of ID claiming that there is suspicious activity in my account and was suspended, when actually I cancelled my account after reporting the hack. Cruzroy, do you know if the source of the batteries also has Instagram? that account I had no problem opening, even though they belong to FB.

Brian Fist · Feb 1, 2021

Since I also inquired about the batteries, no the ONLY way they want to deal with things is through facebook.

I sent an email and they referred back to facebook. Quite frustrating.

Inspire 1 battery mod: never ending crusade ...

Since day one it was obvious that Inspire 1 flight time is way too short for serious filmmaking. With TB47 battery and X5 camera payload Inspire could stay airborne for 10-11 minutes, perhaps 15-16 minutes with beefier TB48 battery. Things get even worst with arrival of excellent, but chubby X5R...
