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

What kind of uptime are you getting in your truggy with your 4800mAH packs? I was going w/ the Neu deals, but for the same $$$'s I can get 3 of the zippy's vs 2 4900 Neu's.

15-17 mins i would say easily, if your talking about the zippy-r's from korea, you'll get the same runtime as polyquest, fp, etc. very nice lipos! i will never buy name brand again!

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.

Shoot I can't do the zippy-r I misread the length.. I can only do 158-160mm max, How are the zippy-h 5000 packs? I guess it is between those and the Neu 4900xp packs.. 119 vs 150.

I guess I could always strap in a pair of my evo25 3700's in parallel for the mains, but man that is a lot of weight :) 956oz total

this is where that belt drive center line desgin buggy would be nice battery weight wouldnt matter so much, jsut set the shocks up to handle it......

with my 1515 2.5 d in my buggy i ran a 30 minute amain on my 5s 5000 FP pack it i felt it dump as i was pulling in the pit right after i crossed the line, now my exact same setup in my GS truggy i had for awhile would only run 21-23 minutes, but i was running beadklocks and heavy inserts but the truck prolly weighed an extra 3.5 pounds over the buggy.....


if you wanna run 5s 8000 run two packs one on each side, with the front across from the servos up front, like the caster buggy, this way it wouldnt affect the handling so bad.

or you can swap batteries at half way and stick to the much smaller and lighter batts.

hmm maybe a 6s 4300 will do the trick then, that will provide a little more watt/hr than the 5s 5k giving me what I need to get a 30min main in. With a 45min main it won't be a big deal doing 1 long pit to swap out packs making me even w/ the truggies.

Not sure how big your track is, but thirty minutes just seems iffy in a truggy unless you have huge brick of a pack. It is iffy in a buggy, so I know a truggy is going to be damn near impossible if the track is medium to large sized.

I would just plan for a battery swap at 15 minutes. If your pitman swaps fast, you shouldn't lose too much time to the nitros if you only take one pit stop for the swap. It should be pretty even to their multiple pit stops. I finished fourth or fifth in a 30 minute A-Main out of 12 guys a couple of weeks ago and I had to run out of the stand and do my own battery swap since the nitro guys were afraid of a little electricity, so it can't be that big of a disadvantage.

The math above doesn't lie. A buggy is going to run at 190-220mah a minute during a race. I have been tracking my run time religiously the past couple of weeks. Truggies take more mah/minute. My buggy would need at least a 5s 6000 assuming 200mah per minute and no practice laps to make 30 minutes. Truggies run close to 250 mah/minute realistically which means a truggy would need at least a 5s 7500 for 30 minutes. Assume bumping to 6s makes you more efficient and you burn 225/minute you still need a 6s 6750 for 30 minutes. Say you really feather the throttle and gear it fairly slow and you get buggy efficiency of 200/mah a minute you still need a 6s 6000 pack.

Mah/Minute * Desired Runtime = Pack Mah.

Hmm I guess no matter what I'm doing a swap in a 30min, and 2 swaps in a 45min.. no real gain making it worth the bother w/ 6s

yea i was gonna say you could get the true rc 5s 8000 pack, i run the 4s 8000 in my truggy, i can get about 22-24 mins, i dont notice the handling difference, but with the 5s you just might
