Hyperion G3 45/90C packs finally to market!

A 3300mah 4s pack is $100

Their data sheet shows 4200, and 5000mah packs coming, but they are not available at the moment.

I know what packs I'm buying this year again.

sweet

Two of those 3300mah 4s in parallel sounds pretty tempting to put in my truggy, might have to give them a shot.

Hmm! nice!!!

Everyone keep a look out for availability!!

Thats awesome with just 1 caveat, I want bigger wires. The 4s 45c 3300mAh sounds perfect for my carbon fibre rallygame buggy reducing the weight by near 200g from the 4s 30c 5000mAh I run at the moment, but theres not a chance that I'm going to run a pack with 12gauge wires when my ESC has 10 gauge fitted, and likewise 40-90c sounds fantastic for my boats both for ovals and SAWs but they only have 10gauge wire and my boat ESCs have either 8guage or twin 10gauge, my Zippy Flightmax 30-40c packs have only 10gauge too and their wires are the hottest part of the system, there's no way 10gauge will take half as much continuous power again and as for bursts 10gauge is just a joke for carrying 450Amps.

this is fantastic - from what i've seen, thunder power is the only other company so far with 45c lipos. i have 4 hyperion 6s 35c lipos for my trex 600e, and they're absolutely amazing. as my lipos for everything poop out, i'll be replacing them all with hyperion.

I guess I don't totally understand the need? If your not tapping out the 35c's (227A cont), where do these fit in?

I haven't /don't hear of too many complaints about the existing hyperions with regards to heat or discharge rate.....????

While I'm all for updates in technology, I have a hard time with it in excess....

My. 01c.

Personally for me, Iam a basher not a racer so I can run a smaller lighter battery back in my cars and have a better performing and handling car at the expence of run time with higher "C" rated batteries, and for my boats I have a bunch of 240A controllers it would be nice to be able to pull 200A from the batteries although these will need a wire change to do so, also with a 450A burst rating I can run 2 motors and ESCs from 1 pack for a few seconds and hopefully get myself a record.

For car racers that need a 15 minute run time, the "actual C rating" doesnt matter, as a 15 minute run is only 4C average and even the first generation of LiPos would manage that, however there are 20C spikes that 4C batteries couldnt deal with and it wasnt till the 10C cells came out that LiPos were man enough for the task so you might say why not stick with 10C batteries and save a bunch of cash? The answer is that with every increase in "C" rating comes an increase in voltage under load which becomes even more apparent when used at less than its max "C" rating, a 10C pack would drop to about 2.8V under those spikes and only recover to about 3.2V between the spikes, wheras 45C cells will hold about 3.7v in the spikes and recover to full battery voltage in bewtween, a difference of 3.6v on a 4 cell pack which with a 100A peak is an extra 360Watts, or a whole 10th scale touring car more power than you had with 10C batteries. If 45c give a just couple of tenths of a volt under load more than 35C cells that is still 80Watts more power. As well as the power advantages the further under its rating you use a battery the cooler it will run and longer it will stay in good condition for, also I normally see an increase to my run time as well as extra power when I upgrade my cells for the same mAh rating which points to an increse in chemical efficiency.

That's exactly right Paul, every little bit of voltage makes a big difference in power, and to some, (me included) SYSTEM EFFICIENCY. The higher the voltage stays under load, the less power is wasted, and the more energy you have available to make a longer race, important for those longer 30 - 40 min mains where you want to size the pack just right... you want to only switch packs once in a race, so you want the smallest possible pack.

You may not EVER come near the 45C rate, but that's just the way they are rated.

You can use a pack like the 25C CX G3 lipo packs that have higher mah/g, but the voltage drops more, so that benefit is reduced, and IMO, I would rather have all the power you need, and have almost the same overall energy density. Plus, the lower rated packs, the higher rate you discharge them, the more mah capacity they lose, more so than packs like a 45C rated.

ThunderPower has 50C/100C packs if anyone didn't know too, but they are too expensive to make the difference worth it.

I guess it does pay to ask the "stupid" ? Thanks guys for laying it out like that, makes alot more sense now.

Just a heads up. The 45C packs are in stores and should be shipping.

Guess I missed this the first time around. Exciting news and the prices are awesome! Still hard to believe with these around others can get what they charge for their inferior packs.

Exactly. Especially when I can get 2 of these Hyperions for the price of 1 Maxamps... :whistle:

This name just pops up in a lot of threads for no reason like a bad weed you can't get rid of. :lol:

I just went and checked Neu's site, and they have the SP2 rated at 46/92, and the SP's rated at 40/80. Funny though, the SP2's are cheaper than the SP's. The best buys they have are on the XP's. It does appear that Lipo pricing is noticably coming down.
