Because getting OEM batteries is spotty at best, we purchased TB48 replacement-packs without BMS direct from China some time ago. We were questioning the actual capacity at first. Having bought some more, we thoroughly laboratory tested them under high load. They do in fact perform well under...

Very poor form from TRB as we are informed only after 4 weeks that the product is officially discontinued. I cannot recommend this supplier.

We've been trying to purchase access to the "TRB" Repairment Tool for about a month and have been having no success. The tool is advertised as capable of sealing and unsealing the TI-bq78350 BMS chip used in Inspire-1 TB47/48 batteries. Last message from Pat Boon of TRB indicated that they are...

You may indeed well be right. However, for our purposes, the added redundancy/safety and reduced main battery heating/longevity will be well worth it. There are many experiences of expensive machines falling out of the sky to destruction due to having only one battery. We'll see.

While the experiment yielded interesting results, it is clear that increased static run time does not yield directly corresponding flight duration. This is because increased battery capacity also increases weight. However, though not proportional, some increased flight time can be expected. The...

We ran a static test of two parallel saddle batteries, 2x1700mAh (3400mAh), on a TB48. Total weight of the two saddle batteries is 418grams. The TB48 weighs 667grams. An extended battery run duration by an increase of approx. 66% was observed. The test was performed on the bench with a...

Turns out the other problem, as learned from "PatboonLabs", is that BQ78350 BMS cannot offer reliable communication through the SDA/SCL interface port of the TB48. The MSP430 chip in the TB48 controller board is constantly interfering with communications through SDA/SCL. This can be circumvented...

Seeking to obtain dead inoperable TB47 batteries to be used in experiments.

Been trying to find a good way to get into the BMS chip in the TB48 (TI-BQ78350) and didn't find anyone who has a good system for doing it. Contacted Nicusor at 'Nip Embedded' but he says their system NLBA1 hardware and software presently does not support that BMS and gave impression there was...

What you say about handling is right on mark. It becomes a trade off of handling vs a little time gained aloft. Making saddle batteries a "mission configurable option" chosen depending on the flight-mission and weather/wind conditions is the way we will go. Higher winds with heavy loading...

We will likely convert all of our inspire batteries to have this harness. The additional benefit is that, with the conversion, the bird can easily be outfitted with dual saddle pack batteries which can be mounted & plugged in when needed for increased duration and safety backup.

I agree with some of the ones who advised against using them. I tried one of TB48 types and it reported in at 3973 mAH. Using same discharge resistive load on a DJI TB48 and the HSABAT confirmed that the HSABAT discharges significantly faster. I'll not buy any from this supplier.

This is a TB47/48 Balancing Harness we made for external charger balancing batteries that have gone far out of balance. Such batteries would not operate correctly. The battery was discharged down to Battery Management System (BMS) Shutdown. The residual individual cell voltages were then...

Also, how would you want me to pay for the shipping?

Let me know what state you'd be shipping from & ship cost and how many you have of 'not working', 'tops-only, 'swollen' etc...
