Nice! Looks like Redondo Beach has a Typhoon and is using it at the moment.
Saw this on Facebook in a 3DR Forum Post. FYI
One of my batteries went Tango Uniform

Everything appears to be solid? I was expecting a chip in there. Perhaps it between the Battery Packs? IDK... Good luck 3WM and let us know how you fare with yours.
No need for any kind of smarts in these; they're just plain old garden-variety LiPo cells in a proprietary package, unlike DJI's "smart" batteries (why anybody would want to make smart batteries is beyond me, other than profit margin).
You could use any 3S batteries that fit in the hole; solder on this connector and off you go.
Haha.... I was just about to post that very thing.
Some type of LiPo's wired in series.
Any idea what they are? Volts and mAmps?
Looks small for a 3S? IDK?
I think I may need a new Multi-Meter.
It would be nice if 3WM could get his open and replace his with something like this for under $20?
I could make a 3rd Battery for mine as well.

These days pretty much all multi-cell LiPos are wired in series.
Nominal 3.7 volts per cell
mAh capacity for individual batteries (if they're all the same and wired in series) is whatever the pack capacity is.
No need to open the old one, just cut off the connector and stick it on the new one. If you want to discuss it further PM me.

Thanks and thanks for the simple schematic. I did check my good battery fresh off the charger and it was showing 12.6-7 volts which should be about right. Now I need to dig out the soldering iron.
Ok, just pried mine open while watching a movie. Nothing obviously wrong, so one of the cells may have failed. So it may be a faulty battery. Just realized my soldering iron and tester are at the office. Fly, where is that battery pack you posted available at? If someone smarter than me would tell me how to do wire it up, I'll do it.
Also, if you decide to go this route be sure to cut the battery wires one at a time, and don't let the bare ends touch or angry pixies'll come out and ruin your day.
Prathbun! You are the man! So blue and yellow are negative? This looks so simple even I can do it...lol.
I'd rather not create my own personal Galaxy Note 7 incident. I'll keep that in mind. I'll clip and bend each one a separate direction...lol
In my drawing, blue is positive for the black/blue cell; negative for the blue/yellow cell. Yellow is positive for the blue/yellow cell and negative for the red/yellow cell. Each cell is only 3.7 volts. 2 cells gives you 7.4 volts and all three together give you 11.1 volts
Make sense? I'm probably not being very clear...

I get it now. I wasn't thinking in terms of series. Gotta excuse me, it's been a long day...lol.
No worries. Takes a spell to wrap your head around it.
In this case the blue and yellow are sense lines for balancing only. They don't carry much current at all. The only reason they're brought out on the Breeze connector is for charging/balancing. On my TH, if you look in the battery compartment the only connectors are for the ones at either end; I suspect the Breeze is the same.

It should, but the charger may have its own idea of what the capacity should be. What's the capacity of the original vs. the Venom pack?
Venoms can take a lot more current than the stock batteries, so there's no worry about over-amping it (probably;~). The only issue I can see is if the original has a lower capacity and the charger has a programmed mAh cut-off (not likely). Worst case is that you end up with a battery that has the same mAh in it as the stock one, but you're just not charging it to capacity. Like putting a bigger gas tank on your car and only filling it as much as the old tank.
Another thing to take into consideration is weight. Does the "new" pack weight more or less than the original? If it weighs less, then you're a winner all the way around and may want to hack some more batteries...
