Default Packs for my Logo 600SE

As I mentioned in my other post, I am now building a new 600SE V1 kit with most of the applicable updates. Will be 12S powered. Hacker 400kV motor.

Any suggestions on currently good packs? I am thinking I want them in the 12S3500-12S4000 range. Was thinking of going with Revo's 6S3700 420 Blend.

Is there any feedback on something better? Thinking I'd not spend for the Thunder Power unless they go on sale. In my experience, though, they're very good in terms of weight/size/performance. Just pricey.

My bird will be light. Futaba BLS 253/251 servos, Jive (as in, no external bec or pack), and iKon2.

12s 3700 should be perfect Rob.

When I built mine (I was swinging 693’s), I went 12s 4000’s and they ended up feeling a little too heavy.

The only other thing is that if the Revo 420 Blend’s are slightly heavier than standard blend, they might put you back on the heavy side.

If that’s the case, I’d suggest 3300-3500’s instead.

As for recommendations, I still think Gens Ace are the way to go. I’m still flying some that I purchased in 2012. Other than those, I’d look at Pulse or Optipower.

Thanks, Dave.

Many 3300's out there for selection...not so many 3700's. The Revo is 1/2 the cost of the GA, Pulse and OP though.

Really look at weights as there is a big difference in weights on some packs. The latest Gens Ace 5000 45c packs are lighter than lots of 4500 packs out there and perform extremely well. I had some other high end 6s 5000 packs that where extremely heavy in comparison.

My 600se is still slightly tail heavy with admiral 12s 4000mah (600g ea).

But I don't have the motor counter bearing, also only running CC 80hv up front which doesn't help.

How far forward is your pack?

Ask me how I knew that

Interesting details as always. Dennis is correct. Looking back at those Revo's I linked above, they are 620g/ea. That might be a bit much. No hurry. Not as many lighter packs in the sizes as we had a few years ago. C ratings have mostly gone to 45+. I used to fly Sky 30C 6S3000 x 2 in my 6HV Ultimate. They were terrific packs. Don't see them around anymore. The 12S4000 pack I have is a 30C Spyder that I bought from Progressive RC. It's been an excellent pack. I bought it to be a light setup option in my 7HV...also a pack no longer available.

I may get a bunch of these and run them in ALL my helis. This includes my 550 ultralight, TT e700 and a 600-3d.

https://www.dinogylipos.com/collecti...12393375203424

I've had MarkF's 6s3300 graphene 2 "70C" (30C real world continuous) packs for the past two years and I've been purposely abusing them to see if they would puff. They haven't puffed at all. In fact, except for some cuts in the covering from drops and such, they essentially look new. By far, these have been the best packs I've ever owned.

I had some Spyder 6s4000s back when and those eventually puffed up. I had Glaciers and those all puffed up pretty fast. I had Pulse, and those took a while but eventually puffed. I think the only packs I've owned other than these Dinogys that never really puffed were the OLD Thunderpower Prolite v2s. But after six or seven years of use, the TP IRs finally went through the roof and I tossed them.

WOW, if that weight spec is accurate, those are light for 4000's...reasonable on price too. My Spyder 12S4000 is still in good condition...LOL

that is...in spite of a fire I had with the balance tap one day at the field. It burned through the shrink wrap on the stick, and I was able to put it out. Replaced the taps and shrinkwrap with no other apparent damage.

MarkF has my 6s3300 listed at 505g with no connectors. I have AS150s and a strip of fuzzy velcro on the bottom of the pack.

Also, it seems I've had them for a bit over 1-1/2 years as my label says Oct 2017. Oops.

That is a nice light battery Prototype and very similar to the new Gens Ace packs. There 60c 3300 6s is listed at 506 g .

Dinogy packs are NOT Gens Ace cells. Dinogy has their own factory and engineers.

OTOH, Pulse, Glacier, TP and many others ARE GensAce cells.

Who said they ARE ! What is with you, I said they are similar as they are listed at 1 gram difference. I am not trying to say anything about your packs except they are 1 gram difference. Take care

In a market saturated with rebranded packs, custom labels and the chinese cell shuffle, I think it is important to point out that Dinogy packs are not a rebrand.

To be honest, I wonder who is making the Optipower cells but I'm not curious enough to buy them and watch them puff. Also, based on what I know, I think anything not "graphene" based is obsolete and I've been told by GensAce that they won't produce "graphene" packs. Dinogy doesn't do sponsorships or anything so I know that is why you don't see any pro pilots using them. I'm fairly certain that the pros use the packs they use since they're either free or discounted and, honestly, they may not know there are better options out there.

I use what I use based on my experience and my own testing. It also doesn't hurt that I work somewhere, where I get to handle, inspect and test a lot of r/c gear.

I purchased MarkF's premium packs with the mentality that I was going to purposely abuse them to see if they were worth the "premium" price. If they had puffed or failed me otherwise, I was going to start buying cheaper packs because I was sick of paying premium prices for a custom sticker on a junk pack.

This is the ONLY battery thread on the internet worth reading.

All of this discussion has had me rethinking my setup. I had initially planned 12S because I could share 12S3300's with the 600SX. But, I am now rethinking a bit. There are many cool setups on lower cell counts. I have a Thor 7S4400 pack that is like new. I have some 12S4400's and 12S4500's which could be separated for a 6S bird. I just don't yet know what I will like. I've flown my 7HV (before conversion to Chronos) on 7S, and didn't care for it. Just felt too anemic. But, I didn't re-pinion for the lower count.

Maybe I'll stick to 12SD for now, and try my available packs and have the fun of experimenting with that 7S4400 pack if/when I find a bargain motor with higher kV. I noted that Timo's 600SE 6S rig was using a Tango 45-07 which has 720 kV. My impression is that it flies nicely on 6S5000 with that power setup...but, of course, he's a terrific pilot as well. I thought perhaps a 4035-560 on 7S with a 14t pinion could be pretty decent.

The Kontronik Tango is a rather unique motor in that it has no iron in the stator and so the "iron" losses are nearly zero. It is also a fairly heavy motor.

I ran my 600se on an xera 4025-560 for a while (link to thread in my signature). This is a VERY light and very efficient setup for ~1300rpm. You need VTX, Rail or MS composit Rapide blades on this setup to have reasonably quick cyclic. If I had liked it more, I would have run 6s6000 packs.

For a long time, I wanted to run 10s like the original spec for the 600se as this provides a nice blend of efficiency and "fun" headspeed but in the end, I decided that I would rather de-tune my e700 to fly like a 600se and build one of my Logo airframes as an aggressive 600-3d.

My initial plan was to simply emulate the 10S setup in 12S. So, slightly lower capacity 12S packs. This was where I figured 12S3700 or so. Not many out there. Original 10S4300 or so would have been 1000-1200g depending on pack choice.

Is there any other reason to prefer a 10S power system over a similar 12S setup?

I can't give you an exact answer there as I don't have the right technical specifications for Kontronik motors. To me, this is important because the original recommended setup was 10s4500 and a Pyro700-52.

Was that like from the days when Readyheli showed the suggested setups? I think I recall those. I have the 700-52L in my 600SX. Nice motor with light weight. The Hacker I bought isn't that light, but it's on par with other 700 motors, albeit 400kV. I think those Dinogy 6S3700 65C are about spot on for the ideal 12S arrangement. Considerably lighter than most anything I have seen that is comparable.
