Battery for HK-4525 and 4530

[aviator493]

Im going to use spyder 12s 5300mah 30c batteries. From what I hear they dont over state theor c rating like other companies do. Will these give me full potential of this motor? From what i can see 25c battery is most you really need, but msybe im wrong?

Sorry no you wont get full potential of the motor, not even 65 c will give you full potential but they are much closer and will last at least. On 30c anything close to a power setup on a gov with enough headroom will puff your lipos, so if you fly not agressive they will work, but why waste money buying a bengal tiger and feed him vegetables? I have a saying when you want a power setup, first get the right esc then the batteries and last the motor!

Well..this may help you decide!
I currently fly the Spyder 12s 5300mah packs in my Rave Ballistic 90, with the 4525 520LE and the Ultimate. I get incredible power results with this setup!
To compare I've flown a friends Ballistic with almost identical setup except that he is flying Thunder Power 5000s and I could tell absolutely no difference in the power between the two machines!!

I've currently got several Spyder 12s packs and fly pretty hard 3d at 2050rpm with 13deg of pitch and get 5min of flight time putting back about 4000mah back in the pack! My oldest pack has 160 cycles and does get warmer than my new packs and Ive been flying only 4:30min on it but it still pulls just as hard as my new packs for the entire flight! IR on it is still excellent at about 5-6 ohms per cell according to my icharger!!

Thats great to hear!!! I may buy some more. Unfortunately I totalled a 700e today on 3rd flight and destroyed a pack....

I've never tried Spyder batteries, but I can tell you that 30C GensAce 5300 packs bog like crazy, and my 45C Voltz 5100 packs are starting to puff. Thunder Power 65C packs are the only ones that seem to be able to keep up.

Trex 700, Jive 120, Scorpion HKIII 4035-560 with 12T/112T, 13 degrees pitch, 690mm mains. 2250-ish headspeed. According to my JLog2, I pulled 8200W and 207A with this setup just yesterday.

I'm thinking not even 45C batteries are enough if you're pushing it, especially with these new monster motors. I recommend investing in quality battery packs (yes, I know it is obscenely expensive). I have a feeling this "True C rating" thing is just marketing propaganda to keep selling packs to people without data loggers.

I wonder if the Gen Ace and Spyder packs are basically the same thing? All the numbers line up as well as the weights? I don't mind spening the cash on the larger packs, however I did total a 700E yesterday, so even though I'll be using a motor that is overkill, the Spyder packs may be ok at 2100 and 12 degrees pitch until I step it up more.

By the way, what are you using to log theses numbers? I'm thinking maybe I should be doing the same.

I'm using a device called a JLog2 (http://62.153.249.80/jlog/en/). There is a Forum here dedicated to it. It really is a great little tool. It's only available from Germany though, so it can take a while to get one.

Regarding batteries, go ahead and try a pair I guess. I usually evaluate packs one at a time (or two at a time for 12s). See how they hold up. Data logging tells the whole story though. I can pull more watts and more current through the same ESC/motor with higher C packs, even when they "feel" similar. I expect it to be more pronounced with a more powerful motor.

I'll throw in my two cents... I fly Voltz 65C 5100 mAh packs and really like them. I'm on my second season on the same packs, beating them up pretty hard with a 4525-520LE, maxed out, flying down to 9-10% and they haven't puffed and put out plenty of power.

I do take care of them, I always set a timer and fly down to 10%ish, never leave them charged over night and always return them to storage voltage after flying. I charge them at 3C at the field and 1.5C before I get there.

Thanks, Matt. Yeah, I've had great luck with my Voltz packs fo my 550! I've videos of you beating the crap out of the heli so I know they work!!!

Just to add to the story with my Spyder packs:
I've heard MrMel mention that running the vbar Gov tends to keep your peak amp draws at a minimum due to its active throttling as opposed to the reactive governing of internal governors. I have logged several flights with an elogger to my setup and have only once or twice in a flight pulled peaks upto 170amps. Now, there are obviously people that fly much harder than I do, and I'm sure that someone lese could punish these batteries more than I do, but for the setup I have, I couldn't be more pleased with my Sypders and the way they have held up so far!
I have seen and heard that Genes Ace packs look/fly very similar to Spyders..I've never tried them, but the customer service from David at ProgressiveRC(Spyder distributor) cannot be matched. It's worth the extra $ in my opinion. Ive heard of people who have had a dead cell in a new Gens Ace pack that were basically plum out of luck as far as a replacement/warranty! So take that for what's its worth as well.
Anyway..good luck with the decision, just hoping to give you some info to help you decide!

Right now I have 2 of the Hyperion 12S stick packs and 2 of the Spyder 5300 Packs. I'll start with them and see how they work. So far the Hyperion pack has done well with the Align MX motor!

Please post your jlog .lov file, i need a stock motor file Tnx
My tp's have been doing well on my compass 7 and others http://helifreak.com/attachment.php?...0&d=1334464945

[NRPY]

I'll post it when I get home tonight.

How does the 7HV compare with the E720?

[Stolla]

Thanks for file, will download on pc later,7 is heavier and noisier, if it wasn't for the crappy quality tail on 7 I'd say quality is very good. 720 is a special heli with lots of innovation,7 hv flies fantastic can handle big power as well but slightly lower quality especially tail, also smaller although its a big 90 as well. I replaced my logo 600 se with the 7 and bought 720 in place of goblin. I'm super happy with my choice
compass is bringing upgrade tail soon I believe, if I had to choose one it would be rappy by a small margin. lastly 720 parts are more expensive so compass better option if you wanna risk more
