It looks like Thunder Power, no longer do the "TP2100 Gen 2". They have replaced it with this by the looks. So we no longer have the perfect fitting Trex flight pack.

TP2000-3s Pro Lite.

Cheers, Hayden.

But the TP 2100 fit perfectly. Time to go stock up before they are all gone.

I was at my LHS a few days ago looking for a spare. They had none in stock and indicated they could not get anymore.

Someday, I might put a cute statement here.

TP better think better about this. There is alot of TREX users out there.
I ordered another TP2100 this afternoon. If they no longer offer a perfectly fitting pack I WOULD have REASON to look at other ILL fitting packs that cost a helluva lot less than the new "pro lite" series.

TP are you listening?

If the new ones have more punch to them we can always use the world famous Jarod hair dryer trick on the canopy.

Still have the Apogee 1660 3s2p as an option. Very similar form factor to the TP2100, plus it's lighter and 10.5C. It has less mah but the wieght difference may make up for that (depending on your chopper)

They still show the 2100 gen 2 packs on their site.

TP are you listening?

From the post above, I would say YES!

....there goes that CA glue sticking to my fingers again!!!!

I can't see how it's going to fit as well.. the Tp2000 is shorter but wider and the same height.. I guess since it's shorter and weighs less we don't have to put it between the frame right up to the motor. It also costs a little more.

Here is a link to the manufacturers website.

$85, ouch. I was hoping they would come down in price not go up. Im sticking with the older version for as long as I can. I think its time to find a new lesser expenisive defacto battery for the T-Rex.

Okay I am confused. What is this "nominal" voltage and why is it so low? The TP2100 is rated 11.1 volts nominal.

"Output: 7.4V Nominal, 2000mAh"
must be a typo.

The TP2100 fits snuggly between the frame just infront of the motor because of its 34mm width. The TP2000 has a 50mm width. Now how is that gonna fit in there?

Not sure if these will fit the the t-rex.

Ditto! ME too! I wanna know!

Ashley or Gary- can you post a pic of your 4S pack on the batt tray? With and without the canopy would be great. I think that would help clear up this debate.

I'm a huge fan of the 2100 cell form factor- I have four 3S packs. I love that they fit in anything I care to fly, helis, sport planes, sailplanes, hotliners etc.

The 2K Pro-Lite cells are the new latest and greatest product from TP, of course they're going to be a little more expensive. They offer incrementally better performance at a lower weight. Personally I'm psyched to try the 4S packs- I think the extra 25 bucks for a fourth cell will be well worth it considering its only 10g heavier than the 3S 2100. A higher Voltage under load and a higher burst current capacity sounds like a good match for 3D helis. Even if you don't use the higher C rating, it means the pack is more stable under heavy load and should last longer.

Sure there are lots of cheaper cells out there- I'm sure TP will keep a close eye on their marketshare and adjust their pricing structure accordingly as any business needs to do. Right now IMO TP has a top of the line product and top of the line service and they can justify the additional price.

That being said, I think TP is going to upset alot of the EP Sailplane and Hotliner guys if they don't have a long skinny stick pack configuration for those long skinny fuses.

Personally, I don't how the width really matters as long as the pack fits in the canopy. I use TP1900s which are about the same width as the new cells without a problem. Due to the 1 ounce reduction in weight you're going to have to move them as far forward as possible to maintain the CG.

The last time I looked I saw a $30 price difference for a cell that won't
fit AS WELL , so I guess now I can shop other ill fitting cells for less.
So they listened and choose to ignore me, oh well. My dollar spends fine elsewhere.

There are others to choose from

Those won't fit either. The TP2100s are 34mm wide and barely fit. How is a 40mm wide pack going to fit?
