Default 1/8 Conversion Batteries

The 1/8 conversion threads are getting a bit too thick for my liking so I would like to start a seperate thread for batteries.

I am converting to EMBX6 and EMBX5T. I am sold on MMM's and the Tekno Neu <2000KV motors with a 5s1p setup.

Is Hobbycity the only distributor for the ZIPPY-R packs? What capacity would yield a solid 15 minutes RACE time? What is your opinion on the max weight for a race application?

I am not opposed to spending the dough for polyquest but if a more reasonable option exists....? As a racer for a couple classes I will end up purchasing 6-8 packs and I don't want to set my summer up for failure. Do you think the polyquest would get 4 times the cycles and be cheaper in the long run? (please know I am refering to the Korean made Zippy-R for comparison not the Chinese version).

Thanks for your input in advance and let's keep breaking up the 1/8 scale conversion threads some more, it's a full time job keeping up on the new posts.

NeuEnergy sells batteries at a descent price. The NEU4300XP 5S1P V1 might work for your 15 minute runs. Might be a little short on run time but it depends on how your drive.

Thank you for the input.

5s 5000, That seems a bit heavy (over 600 grams).

Any idea what an ideal weight is for buggy/tuggy racing applications?

The Neu packs seem well priced, what cells are they using?

For the buggy, get the Zippy-H 5s 4000 which will get you through a 15 minute main with no problems. I run a 1512 3d with 5s and make 15 minute mains with 3 minute warm ups with no problem all year long.

The zippy's are not as nicely constructed as the more expensive packs, but at half the price of the major brands, they are worth it. I have only had one go bad on me for no reason. I have six Zippy-H packs and they all are perfectly balanced and I put the full mah back in them after almost a full year of weekly use at the track.

The NeuEnergy packs are very nice and what I primarily use now. To get 15 minutes go with the 25c 5s 4300 packs.

A 5s setup with 4000mah typically yields about 20 minutes of run time.

For the truggy, you will need to get a 5s 5000 pack to make a solid 15 minute main. Truggies burn more Mah/minute than buggies. Go with the zippy-h 5s 5000.

The zippy -h are 20-25 packs and the zippy r are 25-30c packs.

I'm finding that the Zippy 5s 4000 packs are getting me 20 min of hard runtime. I'm using the Castle-Neu combo in a Losi 8 2.0 buggy. So far i'm very pleased with the Zippy packs. I did learn that in addition to the hold down straps, velcro on the battery tray and the battery is highly reccomended to keep the battery from sliding and getting damaged.

Wow the neu batts are rated 2C and 5C charge rates, insane. I need a huge charger now. The zippy ones look pretty cheesy. Sounds like alot of you guys use them. I always used TP and FP. Never tried a cheap battery.

Lipo's are just like car batteries in the aspect that there are very few factorys that make the cells but, many,many places that put labels on them.

Only probs I've read about Zippys is construction related. The individual cells are apparently not glued together inside and if the pack is not well strapped in, that can pull wire off cell(s) as the cells can move relative to each other. As long as they're well strapped down, shouldn't be a prob.

Also Zippys use aluminum tabs (copper is better) and they are not as consistant as the premium brands. On my NeuEnergy batts after discharge each cell is within .01 volts, on my Zippys they can be off as much as .2 volts, Also, out of the 4 Zippys I purchased, one had a bad cell, out of the 3 Neu batteries I have zero isues. That being said, you can't beat the price of the Zippys, I use the Zippys for practice/tuning and the Neu's for racing. The reason I have so many is I have a buggy and truggy and I charge my batteries at .5C which is susposed to extend there useful life. So I need several in the rotation. I also have some Protek, MaxAmp and TrueRC lipo'sand they are ok, but the Neu's are better (and most expensive) and the Zippys are ok (but way cheaper).
