I am sure this is going to start a flame war and if it does I will shut this down. I am looking for empirical data on this.

On one of the other forums for a heli that I have someone mentioned that they "never use HK batteries because they got one with a bad cell…" and that they only use batteries like "glacier or TP" Then he mentioned that the cell that went bad was on a 6S battery and this particular heli forum only uses 3S batteries. I thought this was an apples to oranges comparison. So has anyone used the smaller 3S or under batteries for comparison to find an empirical difference. Specifically Turnigy Nano-tech A-Spec 60C vs Thunder Power Magna Series 70C

Obviously the difference is $14 but has anyone actually used the two and found that the TP is that much better? I also know that the budget Nano-Tech's are no comparison to the "budget" Thunder Power batteries. So I tried to pick apple to apples batteries (60C vs 70C)

I would stick to Pulse Ultra. At $13, this is all your going to need. Says out of stock, but try anythingheli or many other retailers.

But still my question remains. Has anyone directly compared the "top of the line" Turnigy against the competitors?

Thanks Slyster. The reason I am asking is because I got my first plank and it needs 3S 2200mAh packs and they recommend at least a 40C rating. They say that a 4S 1800mAh pack will work and only requires a 20C rating. I want to buy the best bang for my buck but am not oppose to owning a few high end packs if they actually make a difference.

At the relatively low cost of those particular size batteries if I were you I would just pick up a TP and draw my own conclusion for the heck of it. I mean what's $15 in this hobby?

Danny Dugger · 12-29-2015, 06:27 PM

Just got an email for 40% off from TP... coupon code HOLIDAY15. Might as well give it a go

Pilot, I did a back to back flight on a new (sub 10 flight) Turnigy Nano-tech 65c 6s 5000mah (before the A-spec batteries came out) with a new (sub 10 fight) Pulse ultra 6s 5000mah 45c battery.

I was flying a fairly new trex 550 with a talon 90 and 600mx motor. the turnigy flew it fine and performed well but the pulse had a more distinctive punch out, more power on demand than the Turnigy.

I also had a problem with the Turnigy batteries puffing up early in their life.

When I flew a trex 450 I had five nano-tech 2250 3s batteries that I flew the dog crap out of for a number of months.. I abused those batteries and they worked well and never puffed on the 450.

Interesting! This is what I was looking for. I also plan on buying a TP battery since they are on sale. I unfortunately it's only good on one item. So I have to decide if it will be a little heli battery or a larger plank battery

So I had a mishap with my 180 and took a pretty hard digger. I was using a brand new zippy 500 pack. The balance plug got ripped off and the battery shorted..not sure how long. I recently got the nerve to solder on a new plug and check the cells. 3.88 4.12 4.13 that was after sitting several weeks. I balance charged the pack at .02amps and it came out good. BUT..the pack doesn't seem to be puffed but the outer wrap has a bubble on it like it was stretched and then the battery went back to its normal shape. Its not puffy at all just a big bubble in the yellow wrap. I know this didntbdo it any good and I will probably get told to toss it but realistically is it safe to use? I understand its life may be largely shortened but is it safe?

Drivelayer · 12-30-2015, 07:35 AM

'Safe' hard to say, it is risk vs. reward. do you want to risk your heli for a $30 battery?

I will say this, I have flown packs that have been visibly bent, not taco'd but tweaked a little, that the outer covering has been torn off and I wrapped in packing tape. they flew fine for awhile and I have never had one catch fire. I almost always balance charge and usually not higher than 3c. and try to time my flights so that I am burning about 75% of the capacity.

BUT .. .I knew the risk and made an informed decision.

darknight736 · 02-05-2016, 05:26 PM

thunder power All the way. on the same heli got gen ace 6s 1400mah 40c. pulse 1250mah 45c and thunderpower g8 1300mah 70c. about same fly time gen ace vs thunder power and work few season more punch, stay balance, cooler after flight

EjectEjectEject · 02-14-2016, 08:35 PM

I've done a lot of battery testing over the last few years - TP - Revo - WildScorpion - Turnigy Nano-tech. Mostly in 2250/2450 variants (3S & 4S).

Quick notes ...

- Both of the nano-techs puffed early, without even any abuse.

- Revos slightly out-performed TP in terms of capacity, but I think this was only because TP had more optimistic labeling (50mAh more).

- C rating is really only a relative temperature indication - the higher the C rating the cooler the packs should run. Add to that the fact that it's temperature that kills packs - so higher C packs should last longer. C ratings in terms of what you can draw continuously are completely meaningless - try dividing it be about 4 to get a figure that actually works (but is hard on the batt with respect to temps).

These days I just fly Revos - performance seems on-par with TP, but I have had some cells die (replaced under warranty) whereas no reliability issues with TP (although they are literally over twice the price to get them delivered here) (in NZ).

As a strategy I use 2x 4S/5000 in my 550 - I don't like packs with high cell counts - kills entire pack when 1 cell goes.

Hope this helps.
