Anyone running zippy-h 4800 5s geared for around 40-45?

[stum]

Is there any config that will get me a 30min uptime 5s or 6s in a 8ight-t conversion.. I have not had a lot of time on the track to really figure out what I get out of my current packs w/ the present config (weather). Now that the MMM v3 is here she is complete..

tekno v3 8ight-t
MMM v3
Neu 1515 2.5d (48/16) I would switch this if running 6s)

You might be hard pressed to get 30 minutes in a truggy. I can get 25 minutes of race time on a huge track with a Zippy-H 5s 5000 in my rc8 with the 1512 3d which is slighty more efficient amp wise than the 1515 2.5d. That is geared about 40mph. On our smaller indoor track, I think 30 minutes may be possible conservatively geared.

JHautz hit the LVC right just before the end of a 20 minute main (about 20 secs or so to go) in his x-ray with a 5s 5000 pack and the 1515 2.5d. A 6s 5000 might get you pretty close, but I don't think it is going to make it if your drive hard. You can get a 5s 8000 pack, but it will be a serious brick of a battery and your handling might suffer.

I don't think we are going to be able to reasonably do 30 minute mains anytime soon without a battery swap.

So how do the zippy-h's compare to the Neu 25c xp packs? If he is hitting an early LVC a higher "c" rated pack will hold it's voltage a bit longer. Did he get all 5000mAH out of the pack I guess is the real question... before the LVC hit. We have quite a few 20-30min mains and I just wanted to have something that wouldn't require a battery swap.

The Neu packs are definitely better at the end of the run from what I can tell. They stay in balance and I would say slightly more powerful, but not enough difference to justify full price. Sale price that they are now, definitely, but not $200 plus. My zippys don't like hitting the LVC as they seem to get out of balance. I rarely run long enough to hit the LVC in a race, but the few times I have the packs were out of balance afterwards and one cell would have low voltage. Otherwise, they work as expected for a cheapo lipo. When I don't hit the LVC they are perfectly balanced and great power through the 15 minute mains. These are 5s 4000 packs.

My buggy runs at about 200-210 mah per minute on a large track. I believe a truggy is probably around 250+ mah per minute. You will probably need a 6000mah pack to easily make 20 minutes with 5s in a truggy. 5000mah ain't going to happen consistently.

Thirty minutes is going to be a stretch without a huge battery. Figure a very efficient 225mah per minute in a truggy would require 6,750mah to make 30 minutes. Bottomline is you are going to need a 8000mah pack in all likelihood.
