They stay good for many years if you tread them well.
But with all brands... you can run into a bad item. Part the game
I agree about Rhino batteries they do last much longer than other brands (even the expensive brands). I have a couple of them and they continue to have the same performance year after year.

Gens Ace do have better power but the ones I have donít last very long. Turnigy is the best compromise between cost, power and durability Ė I think thatís why they are the most popular.

How many cycles did you get out of your Gens ace before they started to die out? Did the IR increase significantly? Lose capacity?

I've had (2) Rhino's for almost 3 years now, and they are amazing.... Just keep working and working and working....

I also have a couple of newer Revolectrix batteries that I bought recently when I bought my CellPro charger. Those batteries have been great too, and they seem to have a little more power than the comparably rated Rhino's.... I just never see any reviews on them at RCGroups?

Do your planes have a lot of power?

I used them on a Parkzone P-51 with a Power 10 motor.

I have 6 sets of Gens Ace 3300 packs bought about a year ago and all used roughly the same amount of times. Sorry I can't say how many, but less than 60 cycles each.

I stored them for 3 months over the winter period and now 4 out of 6 are garbage. Voltage after storage was a uniform 15v across all packs. They all charged up and rested overnight and maintained voltage. so I thought good to go......

Well now 4 won't sustain more than 7-10 amps before the voltage drops to 12v. Within about 20 seconds they will recover back to useful voltage.

Measured the IR, all packs showing less than 30 milliohms combined.

Same observation on all the Gens Ace I have, 3300/3800/4000/5000 in various cell counts. They all would experience low voltage cutoff seconds into the flight now.

Agree with the Rhinos. I have some 3 yrs old packs that are still going!

+1 on Rhinos

I took a 3 year old Rhino 1250 3S 20c that's been in storage for almost 2 years for a spin yesterday. I didn't have a plane for it for the longest time, but recently picked up one of those pocket planes from banana and to my surprise that 3 yr old Rhino did just as well as a 1000 3S 45C nano. WOT is 19amps on this setup.

Gens Ace do have the most power when new but you need to use them or they will go bad. Not sure why they don’t store as well as other brands. Maybe it was a intentional design decision to sacrifice durability for max power.


If you want long life Turnigy and nano-tech are good but Rhine are definitely the best for sport flyers that don’t push them to max C all the time.

One brand that has impressed me recently is Haiyin. While I only have 6 packs so far of 6s-4000 to 6s-5000 varieties, they have been going strong after couple dozen cycles. But what impressed me the most is their customer service. When a pack arrived with issue, I received a response to my email within 24 hours, and a replacement was sent out the next day. Didn't even have to deal with the BS of sending the bad pack back. On top of that they have a dedicated wharehouse in the US, so you don't have to deal with insane shipping charges. These are now my choice for everyday flyers.

One thing about China Hobby line compared to other brands is they have virtually every size and C rating combo, which is great.

Turnigy nanotechs are like gens ace, good power when new but live a short life. Plus unlike the gens ace, they also puff when they go bad.
