Hi all,
My present 5 cell F3A Lipo that I have used only one season, in 2019, is getting bad voltage drops when I want power from them.
I tested them some weeks ago and when flying I get on all my 5 LiPo packs low voltage alarm on my telemetry when I add full power in vertical manouvres. I did not use the packs for 2020 season but the packs was storaged charged and stored in my garage rather cool.
I use 2x Hacker Eco-X 5S 4600 mAh F3A Competition and they are rather light, total about 960 gram for 10 cell pack.
Hacker do not have them anymore.
I found Roaring Top 5S 4500 mAh (about 465 gram for such 5 cell pack for total about 930 gram for 10 cell pack.
These:

Problem is they do not have it in stock and they have not for quite some time. And they do not answer when I asked them if/when they will have it in stock.
My Galactika EP F3A model from 2017 is on the heavy side from factory so I can not really have that much heavier battery then I use.
I do not want to replace with lighter servos etc, since the Futaba servos I use are fine, I use an ESC I´m happy with and works fine (Master Mezon 130 with BEC). There is not really any cheap way to get this machine lighter so I need same weight Lipo I use and have used for many years. But I can not find it. About 960-970 gram total for 10 cell 4500-4600 mAh LiPo that works for F3A flying is what I want.

5S 4600 mAh F3A Competition I had bad experince with because I first had 5 packs (5 cell x 2) for just two years then they had no punch left, then bought in 2019 in june new 5 same packs but they failed all same summer with no punch left really. I heard it was bad batches made. It was rather expensive for me. Anyway if anyone knows of 5 cell 4500-4500 mAh that works for F3A use max 480 gram for a 5 cell pack I would like to know.
I have in model rather light accessories: very light wheels, Falcon carbon prop and Falcon vented carbon spinner and such. So on the model it is really not much to do to get it lighter unless I swap out servos and ESC to something lighter that I do not want to do since what I use works very nice since many years.
Thanks,
Bo
