I use them and have no real problems. I don't have much to compare too though since these are the only lipos I've ever had.

It seems like they have a lot more power for the first few laps and then they slow down a little, but that might be normal for all batteries, I don't know.

VERY long run time on my 13.5.

Right now we have 2 guys running this combination in the ZX-5sp and it works great. Cars have tons of power and lots of batery life. I run that battery in my 2wd buggy with the 4600 and we also have 3 guys running the b44 with the Trakpower saddle pack and again tons of power and run time.

The Trakpower lipos work great and the 5700 is the most versatile of the Castle motors. Excellent combination for the 4wd.

interesting you say that. I have an SMC 5000 28c pack that is insane for about 3-4 minutes--then noticeably slows down and will run for another 35 minutes on my 10.5 cr.

My Orion 4800 15c loses a little punch but not as much as the SMC.

It seems like the more they push these Lipos the less linear the discharge curve is.

I've been running some of them for over a year now and absolutely love them. One of my more torturous vehicles to run them in is this:

You'll hear more positive things said about the TP 4900 here on rctech than any other lipo. I love mine!

I have 4 of those gold bricks and they work great. Nice thing is they can handle a 10 amp charge so I can charge my batteries full in just over half an hour. I used to run my batteries in series with my truggy and actually melted the plastic around the female bullet connectors. Also noticed that the newer trakpowers are 25C. I have a couple packs that were only 20C. Huge difference in punch between the two. Currently, my older trakpowers charge up to about 4000-4200 mah. That's about after a year and ton of abuse. My newer one charges over 4900 mah but I don't abuse it as much as the others.

Thats crazy, a dual 4900 "saddle pack". But yeah, some companies say its okay to quick charge at 1.5 or 2c. But at the same time they will tell you that you're probably without a doubt shortening the life cycle of the pack. Only premium cell companies like Enerland which are in the TP's and Kokam will even say that if want to you can, but its not recommended.

First off the Trakpower lipos are great. I have had a 3 for about 9 months now and they are still running like new. (Which my discharger confirms)

Now as for feeling a little better at the begining of a run, I agree. Like all batteries lipos start off at a higher voltage and slowly gow down, loosing punch, they do seem to be very consistant during the middle of run.

One of the tricks in stock and 19T we have learned is to wrap them in a heating pad and get them to about 120F right before running them. They will have more punch throughout the run and you won't feel the drop off near as much. It will lower IR about 10%. I don't recomend it for mod though as you don't need the extra power and you chance overheating the batteries.
