Hyperion G3 vs. Turnigy lipo
 

Found these graphs over on RCGroups, very interesting.

I'm so getting Turnigy's for "Frostbyte" next spring, not paying for overpriced racing Lipos ever again.

Turnigy's definitely have a ton of punch and work very well... provided you get a pack where all cells are good. When they work, they work very good though. I'd be willing to pay an extra few $$$ to have cell matching done though.

i just got my 4 30c 5200mah hardcase turnigy packs today for my flux. now, i just need to get some dean's plugs to go on them. these charts make me feel even better about them now. i can't wait to run them. these packs have 8awg wires coming out of them and getting dean's plugs on them is going to be one heck of a challenge. the wires are HUGE! they must be 8-10mm in diameter.

also, i managed to stuff my 4s 5000mah 20c turnigy pack in my flux today and after 10 minutes of standing backflips and speed runs geared at about 45mph, the battery was only slightly warm. not bad for 20c. it heated up just as much as my "28c+" 9000mah SMC packs. i'm guessing the SMCs are less than 20c or even 15c or the turnigy packs are underrated. either way, i like turnigy lipos:yipi:

I ordered a couple of 3s turnigy lipo's for the savage and between being ordered and the retarded christmas rush they only took 6 days to get here! 3 days after it left hong kong they were at my doorstep(missed the delivery dude, have to pick them up later today).

yes it sucks MEGA hard trying to solder the suckers!!
and it looks ugly too but it can be done :wink:

So far I've had good luck with the Turnigy's. mine perform really good in my revo and tc.

since deans are so small, surely putting huge wires on small deans you will be losing some power? because the lipo wont be able to transfer all its energy at once because it will be restricted by the deans? wouldnt bullet connecters (that it comes with) be better?


Also is there anywhere that will solder the deans on when you buy the lipo for you?

They are matched by resistance


I got a pair of the hardcases, 8ga wire is is easier then 10ga as you can hold onto the wire bare handed because it dissapates so much heat. need a high wattage iron to solder them, watch out, your going to need to tweak the wire exits on your battery boxes for the 8ga wire to exit
ITs not that bad when you have a nice iron :)

It sure seems that it's the Turnigy's that are real good. The Zippy's do alot worse. I always kinda figured they were all the same.

Seems like the Zippy Flightmax's do pretty well. Unless I am reading these graphs wrong....

Deans are fine for what we do, they can handle the current draw just fine- its only the extreme setups like very heavy/tall geared 1/8 trucks and bigger that call for something like bullet plugs.

As for soldering, just ditch the deans and go for something better like EC5 connectors or 5.5mm bullets; I sure as heck wouldnt pay an LHS or electrical store ~£10/hour to change over/ solder my battery connectors. Easy work around would be to solder on a short length of 12g wire to the end of the 8-10g wire ( butt joint ), allowing you to solder on the Deans much more easily.

:smile:

Its really not that difficult neil.... just need bigger heatshrink

if you solder on 12awg wire, arn't you limiting the current flow? i mean, it must come with 8awg for a reason, no?

i've got a pair of Neuenergy 5000mah lipos at the moment, and i did a poor job of soldering on the deans. The power I get from them is not as much as I should be getting, and i'm also getting 45 minutes of runtime whereas i should be getting around 20 minutes. i think its because due to my bad soldering, the current has been reduced.

So the package says... But when you get a brand new back where the voltage in one cell drops all by itself when just sitting there, it's hard to believe.

Soldering the 8GA wire to Deans is no big deal. I just tin the end and use my dremel to make a little flat spot so it makes better contact to the solder tab without using a ton of solder. No harder than 12GA IMO.

+1 to that

I've used 14g wire before, and it doesnt deliver any worse power than the 10-12g I have at present; again, for what we do there is a point where you wont see any improvement from using larger wire or connectors. If the wire and connectors arent getting overly warm or hot, then they arent being saturated by the current ( which is what generates the heat ultimately ).

If you have issues with deans, then bullets would be much better as they are super easy to solder, as with the EC5 connectors too- they just have a plastic casing that the bullets press into, making them act something like a TRX connector in essence.

You do need a good iron regardless of the connector type though- I use a 40watt iron for my bullets, though deans probably need something closer to 80watts. Probably...

I am surprised at the poor performance of Polyquest packs compared to the other ones. :surprised:

As for connectors, I used Deans, EC3 and now 5.5 bullets. EC5 would have been much better than EC3 but I prefer my bullets over anything I've tried or seen even though I didn't try some of them.

I tried ec5's but i didnt like them- pain in the but to connect and disconnect- a nice pair of broken in deans can be split with one hand.

with bullets isnt that dangerous cos the ends of the lipo can touch and short out?

Ever heard of heatshrink tubing, and of only using female connectors on the batts? > no short circuits :wink:

I've been impressed with my Turnigy packs, they're in a totally different league than my Maxamps packs and have held up extremely well under heavy load. I had accidentally geared my 14 pound Muggy for about 90 MPH and was able to do standing backflips and wheelies on command at any speed with just the 20-30C 5000 mAH 3s packs (2 in series). They held up longer than my tires, and the only thing that has gone wrong with them is I blew a solder joint attaching 2 of the solder tabs. VERY impressed with these packs. I bought some Hyperion G3s and the 5c charging is awesome and they are all-around excellent packs but for the money I'm sticking with Turnigy.
