Best Lipos for the buck ??

[Accessable]

I'm hearing good things about Dr Wayne's Entropy 6S 100C 5800mA packs.
Have ordered a couple to trial.
I'm running a 12S setup using two Thunder Power G8 70C Pro Force 6S 2700mA in series (yep, bought some more because Dr Wayne is taking his sweet time...)
Will be interesting to see the comparison.

I've also constructed a waterproof box out of 3mm reinforced ABS, Perspex lid cemented on top and lined with 20mm foam for impact absorption.
8 Gauge with 8mm bullets doing the power transfer.
I'll give anything a try if it's worth the effort.

2700 Mah isn't much for a 100 amp drain current. Seems like you are pushing the cells pretty good, chart is hard to interpret. It shows an 80 volt reading when you say you are running 12s at 44.4v which leads me to question the accuracy of the temp sensor I would expect to see some increase in temp from start to finish.

I expect you will see better performance out of the larger 5800mah packs.

Also I only see spikes up to 30 (amps?) on the chart. At least TP replaced,your packs

Figured I'd throw in my .02. Haven't been using lipos very long (about 6 month) but I've been running venom lipos. I'd like to share my experience with them. I've have one go completely bad, but that was my sons fault for using no lipo cutoff. Another I busted open in a wreck so that one can't be counted....but it never caught fire or anything. I had a 3s pack lose a cell. I repaired it tho. Bad connection. I've noticed there is two different ways their batteries are constructed. One way is a crimp at the cells and the other is soldered. Good luck trying to fix the crimped one. Hard as hell to solder flimsy aluminum. Another one I lost in a crash. Can't believe it was a hard pack and split open as easily as it did. And one of the cells was punctured in the process. I did get two of the batts that went bad replaced for free without sending the old ones in. Took a while to get replacements tho.

Another G8 Thunder Power bites the dust...

Here's the strange part - The second pack I use in my 12S setup is one of the originals I bought about 12 months ago.
It still works and recharges/balances fine.
It must have been a "good" one. Probably not made on a Friday.
That's one out of six!
The only consistency I have found is that none are consistent.
Changing brands now.

@ TheShaunessy: Sorry, my bad. Had my software set to 2 Pole instead of 6 for the screeny in my first pic above.
My local TP distributor coughed and spluttered until I mentioned that a good friend is one of his best heli customers.
Cheers.

This is another place I found a while back and these packs are killer, I didn't want to post anything about these till I had some time to run them a while. The guys name is Buzz and he's a really great guy to deal with, a U.S. company with U.S. made packs which is another plus to me his prices are decent too! http://motionunlimitedusa.com/index.php?route=battery

Buzz is a great guy... his shop is only 20min from me and I'm his high amp tester
but...... these packs are not made in the US..
so far these are the best I've tested :)

I stand corrected, I thought he told me one time that they are built here. Could it be that they are assembled here and the cells come from else where?

They are made in China and assembled there as well

I've got 4 of the 5100 6s packs and 4 of the 5100 4s packs and I think they are just as good as the Hyperion packs I have. I'm going to time and GPS each to compare them to see just how close they are.

Mine are better than my Hyperion packs!

Gee I;m getting worried about my new Nano Tech batteries.

As a new comer in FE boats I have had to skimp on battery choice as getting 4 new race boats up to speed from scratch with all the necessary running gear in 3 months for this years racing season it's been tough on my wallet to say the least. My batteries are China Hobbyline and Nano techs . Lately more Nano techs as the Aussie $ has dropped alot so buying Nano techs at the H/K Aussie warehouse is turning out the cheapest way. BUT i'm having all sorts of problems in balancing them up. Never charhe at more then 1C too...My newest packs are'nt balanced from the factory. Their first run today i hope. Been running Nano techs in my cars for the past 5 yrs with no problems but boats are so much harder on them.

Spending $250 on 2 4s packs is the cheapest from over seas is going to really hurt. So annoying .

If you're talking about Turnigy Nano tech batteries, I found that it took about 4 or 5 cycles before they started balancing right and they also are performing better the more cycles I get on them so far.

Nice guy with FREE shipping and his ebay prices are cheaper yet
These are the same packs as Dinogy that are made by LNE

ps. someone rated him out for having cheaper prices, so he had to up his on his site...
