Nanotech 3s 65 c vs. Dinogy 3s 65 c.

[champion221elite]

I have come to the point of FE boating where my current stash of Nanotech 3s, 45 c packs are beginning to show their age. They still run to my time limit, but I'm noticing a few of them are warming up more than the others and coming back slightly puffy. I have two packs that have noticeably less punch than the remaining packs.

Next time around, I would like to get some 65 c packs to better handle the rigors of FE boating. I have narrowed it down to either Nanotech 3s, 5000 mah, 65 c packs or Dinogy 3s, 5000 mah, 65 c packs.

The Nanotechs are about $20 cheaper per pack and I will be ordering at least 6 packs so we're talking at least a $120 difference in investment. Are the Dinogy packs significantly better to justify the extra $20 per pack, or am I looking at diminishing returns past a certain point?

FYI, these packs will be run in a 29" Sprintcat with a Leopard 4082 (1600 kv) and a Blackjack 29 with a Leopard 3674 (1400 kv). Space is limited in both hulls, so running a 6s2p setup or higher MAH packs really isn't a possibility.

I'm all ears, post up your thoughts please.

There has been some testing over at rcgroups and the 65/130c Nano packs deliver a very strong punch for the money
and some guys here are having really good results with them as well..
the 25c and 45c nanos don't have the power that the 65/130c packs do FYI..

my money these days are on the Magnum packs from Buz out of Denver
I'm getting the most speeds and and constant runs with them, they also run cooler for some reason during heat racing

Good info!

I run all Nano techs for my first year of racing FE Boats and so far I have only lost one 2S battery when a cell balancer never cut off after a few days on.

My batteries range from 2S up to 6S with all the ones in between . For value and performance I'm rapt with them . Just wish they go up to 6000 mah in 4s & up in Nano techs NOT the A specs as I can't pick the difference with them.

I noticed you need a good charger as they take a little longer to balance up and after some running in with my new 65/130c they do indeed feel better but haven't race tested them yet.

I've been running venom batteries for a while. Overpriced for sure but still good performance, reliability and warranty. I was turned on to a small company called spcracingbatteries.com and I ordered a few quite a while back just to test them. They were cheap enough to just try them. Well I was quite surprised to say the least. Everything I used them in was faster. Gps verified and had more punch and longer run time. The construction is quality too. I just recent did a back to back test in my rivercat and picked up almost 2mph. I'd at least give then a look. I know I've mentioned these a few times on here, the only reason I do is because they really are a good battery and I'm slowly replacing my collection with them. Another brand (I have no experience yet but I will soon) is revolectrix, their 70c batteries are said to be awesome and very low priced. Check those out too.

Not comparable packs.
All my nanos are puffed easy.

[Brushless55]

The ASpec packs compare
I've got a 3s 2200mah dinogy thats very puffy after 6 flights in a 350QX

[jkr]

Aspec can be comparable but they don't have same consistency.

To puff a Dinogy in the 350qx is easy as it has the cutoff low and those cells don't forgive.

Actually the ASpec are consistent and develop great power.
And I never fly my quads to cut off, even the stock lipo holds up better... no puffing with the stock pack or my Turnigy packs, and I fly those longer.
Not good if they can't go low

Maybe your packs are different batch.

lipos don't work this way.
You can not go with strong cells below 3,80 (free load) and if you want to run more time better use lower c rating packs.

This is how we do it in EU.

just saying the facts about my 350QX
my stock lipo has not puffed and flies the same duration..
my pulse packs beats the dinogy pack all over the place..
I need to try get a Magnum pack to fit it..
also a buddy of mine who loves flying his PA puffed one of those packs as well on its second flight with the dingy pack...

Quote of the week.

The only way you are going to get a definitive answer on that is to buy one of each & test it for yourself.
Battery comparisons are to subjective.
But let us know what you find.

Very true

I have two 4s 65/130c 5000mah nanos and they have not outperformed or lasted the 40c turnigy blues. The nano packs also have smaller wires, puffed quicker and now will not deliver for racing. For my 0.02 (which is about all I have anyway!) the turnigy blue packs have been better value.
nanotech packs 1 1/2 tears old
Turnigy blue 2 and 3 years old
Turnigy blues are starting to go as well now.

Yesterday I ran my Pursuit w/ TP power 4082 2200kv with the nanos in a 4s 2P setup and didn't make lap 8 in a 10 lap race, hit lvc. New they would do this easy. Prop is a cnc 45x1.6, which easy does a 5 lap heat race on the blue packs.

Some dinogy batts would be nice....

The only back to back tests I've seen on here comparing two batteries was by me. I'm not so sure you could really count it either. I ran a 5000mah 50c venom pack against a 6500 65c spc pack. As expected I picked up speed. Had I bought 5000 50c spc packs I would have compared them also but I wanted an upgrade.
