opinions about batteries....

[magman]

OK..looking for opinions here. Seeing as I only bash for now and sometimes don't touch my rc's for 4 months due to my workload, is it better to buy one Hyperion quality battery or 2 inferior batteries. My questions are which will hold up better when used less over a longer period of time.

I have 3 Turnigy 5s batts which work well, but after a year + one is poof and another is on the way... I know that the hyperion G3 line is great quality wise, but how do they hold up in storage, minimal use, etc....

opinions on both sides would be great.


thanks!!

Yeah, if you are going to buy new packs, go for Hyperion G3's, they are built with ISO standards that are just not present in packs built by Turnigy, flightpower, etc... Hyperions are well matched, in both capacity and cell iR. Like you said, if you don't use lipo packs or any battery in fact, for an extended period of time, say 8 months, they will internally corrode, loosing capacity and performance. They have to be cycled occasionally, say once a month over winter storage.

It's always better to have your mind on only one pack, you will usually remember state of charge, when you charged last, yada yada rather than trying to remember stuff about 3 packs.

Good points thanks! Since I use my 5s packs in multiple vehicles, it may be in my best interest to start building a quality battery collection instead of a quantity collection

Hyperion is my vote. My G3 4s 6500 pack sits at half charge for a month some times. It is over a year old. I ran it hard recently it is still great!

I'll counter - get cheap gens ace packs and change them every year...

Technology is moving quickly with batteries

I too would rather just get cheapies and use them as long as I could, toss and repeat without the regret of tossing an expensive pack.

I agree and when the new hyperions came out the quality jump was huge. Hopefully the same will happen again soon.

Well I think you will spend less if you get some good batteries instead of disposable cheapness... in teh long run they will last longer and as far as I'm concerned they weight less, and have better performance. My G3's I bought in early 2009, I'm just retiring them now, and the only reason I'm doing so is because I neglected them for the last year. They have lost only a tad of performance, but the capacity is the only real degradation.

I will be buying only two packs this year, and I race competitively at my local track. I don't want to be relying on flightpowers or turnigy zippo lighters....

If I raced I'd put the $ into hyperions. I just bash, so it's Gens Ace for me.

[magman]

I would try the Gen Ace but, they do not have a 5S 5K 40C batt. I need the higher C rating as it would be used in my truggy or on road car

[brian015]

I use the Gens Ace 5s 4k 25c packs in my Muggy and have been very pleased with them.

25C...interesting. Are you running a dual battery setup? Maybe with these I don't need as high a C rating. Will do some investigating

[magman]

Well I did find these .....http://www.hobbypartz.com/98p-30c-53...p.html....only 30C. anyone have any experience with a 30c in a truggy or alike. From what I am hearing these are better than the turnigys but not quite as good a the Hyperions.

They do have a 60c series but, the 5k 5s is close to the same price as the hyperion line

Nope - one pack at a time. In my experience, the Gens Ace 25c are better than the Turnigy 40c (both have a 50c burst rating).

That is why the RC battery market needs new rating convention... we have no idea what they are basing the ratings on right now, whether it's a combination of temp, voltage, cell degradation, etc.

We need a simple "VOLTAGE RATING" not a C rating, that would be MUCH more informative. For example; at 25C discharge, the cells in this pack have an average voltage of '3.77v/cell'..... another brand on the same test: maybe it's 3.62v/cell

IIRC, back in the day of NiMH as King, brands used to print the "Voltage" right on each cell, based on a 25 amp discharge I think it was...
