I have a bit of a noob question. What would give me a better flight time for cruising on a 2 inch GepRC rocket plus with a naked GoPRO. The 650mah or 850mah 4s? Logic tells me 850 has more capacity. But weight I'm assuming also plays a big roll
Your logic is correct, but you also need to be mindful of how much that quad is going to weight once in the air. A 2 inch can only create so much lift and a 850 4s plus a go-pro is a lot of weight. It'll fly but will most likely handle terribly. I've seen folks using a 450 mah battery on that quad.
I have had one GNB come to me with DOA cells - my experience with the GNB HV batteries is generally high resistance and early sag (I have owned about a dozen or so) - ok for low draw but not great for freestyle burns, can be a decent value if you dont abuse them
@@BartManDude any battery that i dont have to pay crazy import taxes on here in canada - but seriously, while I generally like the non HV GNBs I do prefer the tattus - or my old nano techs, they had some secret sauce
I want to double that experience - has been the same for me in the last with GNB-HV packs. I go with Tattu or CNHL (as they are often discounted heavily)
Isn''t LiHV supposed to be 3.8V minimum (idle) compared to 3.7V LiPo? Not sure about that, but it would mean to stop sooner with LiHV and probably have about the same flight time, still with the benefit of a lighter pack.
I thought the minimums were the same. I remember doing research a while ago and finding this information. I've been flying it like this myself at least.
@@Mangorille my 4s 3" I'll go to 3.4v cause when unplugged it bounces back. My 5" I stop 3.5v Wondering if this higher C one not bounce back as much because doesn't sag as much
@@divingfalconfpv4602I used to fly down to 3.3v but found that I was going through packs faster than I thought I should be. Been going with 3.5/3.6 now and so far the packs seem to last longer.
@@MADFlyFpv they are 60c I haven't maxxed them out yet?🤷🏻♂️ I get 13+ mins of flight on my 5in with them just cruising around do full throttle punch outs with no issues I would like to see how much c really matters because I haven't had an issue
I have a tough time believing these stats. The RDQ 850mah (non-HV) pack is over 100grams. How can they make a HV pack this light? Not saying this applies to RDQ but I did read that some manufacturers provide a misleading mah rating on HV packs.
@@Mangorille trust me I'm just as shook 😂 I got a rekon35 with 2s lions at 3000 mAh and my 850mah 4s 5in build (269g auw) flys longer I've got some new props coming for the 5in want to see if I can make it quieter without loosing too much flight time but 14+ mins is crazy I know the rekon35 max flight I got was 13min and it just falls out the sky the 5in I'm coming in at 3.5v because it's a lipo
@@Mangorille oh another side fact I ran a 3s 18650 3500mah pack and got only a minute or so flight time over the 4s rdq 850mah and the 18600 back is 158 grams I have a 650 mAh rdq non-hv and it weighs 78 grams
Hi man, great vid! I am about to buy some 650 packs and I ran exactly into this dilemma! How is longevity on the GNB? I use the 650 RLines which have been so far amazing, but I was wondering if the GNB's are good in longevity. I do take care of my packs :). I liked and subscribed!
Hey. The GNB packs are still working well. I've stopped flying the Tattu packs now as a result unless I need extra packs for a really long flying session. Stay tuned for a video on the GNB 6s 530 packs. Welcome to the channel!
Well the weight difference is basically just because you have basically a smaller pack of like 575 mah Battery that is sold as a 650 by putting in some additives and writing HV on it. In reality the additives dont help much and 4.35V is still an overcharge. THerefor the lifetime of these packs is significantly reduced. On top of that, GNB is in my experience just making up these C rating numbers. So Tattu R-Line any day
I did some research when looking at these packs initially and couldn’t find any definitive answers. Some folks indicated that the hv packs use a different cell chemistry and are not simply over charged regular cells.
That would be an interesting combination. I think you'd need a fairly low KV 1404 motor though. The Xing/Xing2 that I use only come in 4600kv and 3800kv, both of which I'd think would be too high for a 6s setup.
@Mangorille for only 3 months lol. But I do use them every day and usually 2 charges. On an axisflying c20, I get 5.20 min flights on these. On gnb 850 I get 6 mins. On a gnb 500hv I get

@00fluxone thanks for the info 👍
Thanks for sharing. I haven't had this experience yet but I will keep an eye and see how the performance evolves.
I want to double that experience - has been the same for me in the last with GNB-HV packs. I go with Tattu or CNHL (as they are often discounted heavily)
Yeah been meaning to get the 850mah ones for my 3" i was using their 1000mah & 1100mah lihv that are 110c
Isn''t LiHV supposed to be 3.8V minimum (idle) compared to 3.7V LiPo? Not sure about that, but it would mean to stop sooner with LiHV and probably have about the same flight time, still with the benefit of a lighter pack.

Minimum should be same as far as companies have said but they say storage charge to 3.85v vs lipo 3.8v. You can run them lower
At what voltage do u stop flying lihv batteries like that one?😊
I fly them down to 3.5-3.6 volts per cell, no different than a normal LiPo.
@@Mangorille thanks!

The rdq 850mah HV are 69grams too so I'm confusion why get a 650 mAh

That charger treated me well, plus it has two channels so you can independently charge 2 packs at once.
