Order with confidence now,is a bold statement Andy, i think the damage is done and your statement is misleading and wrong, opti packs i advise or HK if on a budget.

Its up to you,fly what you like.
In my experience they are top quality packs and the order process is now working.
I cant see how my statement can be misleading and wrong.

Seemed pretty accurate to me, my most recent order went very smoothly.

I prefer FP for 6S 5000 over Opti as with FP the packs are not split. As long as we keep getting great results with FP I see no reason to change.

Optipacks are the way to go IMO. Price is the same, order from Fastlads or Midlands have them next day. To me its a no brainer.

The split pack makes no difference when in use at all - just makes it easier for transporting them. The Opti's are smaller and lighter than the FP 50c's aswell so it doesn't get in the way.
I've seen many new FP puff within 10-15 cycles. It does appear to be mainly the 50C nano things which have the most problems. Heard of very very few Opti's that have had any issue.

[Jamin_00]

I certainly don't deny they are a great pack and was a big champion of them, not no more I'm afraid.

The Opti's although 30c I found no difference in performance as I mentioned ages ago before I stopped flying FP's and the split pack is off no concern although I do wonder why no one else has to do it?

I thinks it makes it safe to carry on a plane Ben, maybe other manufacturers have not thought of that?

[jamiem]

I may be wrong, but I believe the reason for the split pack on the large 6s+ packs is down to being able to take them on a domestic flight, whereas a "normal" large pack would either not be allowed, or have to go in the hold. I know that in this case it makes zero difference in use, but if it means you can take them to the RC Hotel, or the UK F3C/F3N teams can take them abroad with them without any problems, that only sounds like a good thing to me.

[Andy from Sandy]

There is a regulation that describes the maximum power output of a battery as deemed to be safe. By splitting the pack into two 3S packs brings the output power under the maximum permissable. The only downside of a split pack is the fact it is another connection. Any connection should be considered as a possible fault area. The less connections the better.

[Mark_T]

Fortunately we have a choice, I'll continue to use packs without unnecessary connectors and wiring and others are free to do as they wish of course.

We should be happy that we do have more than once source of decent packs at reasonable prices.

[Jamin_00]

I know it's because of the regulations etc but why do the HK packs such as Turnigy and flight power etc not have to do it?

Is it because that the Turnigys etc do not reach this power output??

[Grant_beltcp]

Its not compulsary to have them on, it just means you have more restrictions on flying them. Therfore if it's cheaper for the manufacturer to leave them off then they probably will. OptiPower put them on as it saves you the possible hassle in the future i guess. There's no harm having them on (probably less resistance through the onnectors anyway haha) .

[jamiem]

As Grant said, it's not a requirement for the freight shipping, but I believe it is for domestic shipping, meaning that with the split packs you can take them abroad with you if you do wish, whereas you may have a problem if they wernt split. It may be worth asking Andy if they are going to be supplying without the split, as it was spoken about a while back.

Hi Guys, Just been having a quick browse around to see if anyone has been having issues with customer service from FlightPower, and found some issues in here, so I thought I would post and see what was what. I have been using 6S 50C 5000 Nano Ultra FlightPower packs on my 550C and within 20 cycles I started to notice a slight puffing on 3 of my 4 packs. I thought perhaps it wouldn't worsen, but by 40 cycles they were almost round. I have always treated them correctly, well within the 80% rule, and mainly charge at 1C with an accurate balance charger, cellpro 10S. The most I could charge at would be 3C, but I have only done this on a couple of occassions anyway. I am normally putting back around 3500 mAh, but at the most 3800 or 3900. When I land they are only barely warm, as I would expect, since I am well within their stated continuous current rating even at peak power from the motor, not even half way there, if their specs are to be believed. I reported this issue to FlightPower and have received dreadful communication from them, and am yet to receive any confirmation of what they intend to do about it. Interestingly the pack that was okay is still okay, perfect, and in fact I have continued to use all of the packs in the absense of any information from FP. I did stop using the puffed ones for a while, but I cannot manage with one battery, so I am now taking a risk with them. They are now so full of gas that they are solid to the touch. I have now mailed many times and I either get no answer at all, or I get a very short reply such as. "I am still awaiting an answer from the factory. I will be chasing this again tomorrow." but that was many weeks ago.

I have other nano ultra packs from flightpower, 2200 3S for the 450 and 850 3S for the 250, which are great performers with no sign of puffing on any of them, and lots of cycles, but typically, with the large outlay involved for 4 x 6S 50C 5000, I have 3 of them puff. By the way, I have never had any other lipo puff on me, apart from a couple of uber cheap 2200 3S ones I got off ebay, a few years ago. I figured with them you get what you pay for, serves me right. I was hoping it might be the same with FlightPower, in that they are quite expensive, so I expected good quality. At the very least, since anyone can have faulty product, I do expect a reasonable reaction from the supplier to the reported issue.

The lack of attention from FlightPower to my issue has been nothing short of attrocious. I wonder if anyone else has had the same issue with this pack, and if they have come to the same conclusion as me with regard to the support?

Thanks in advance.

Best Regards
