Newer Admiral Lipos have different dimensions and weights... How come?

[themudduck]

I saw where there's a yellow-wrap "Admiral Pro" 4000mah 60C 6S battery in the lineup. Is there going to be a 60C or 65C version of the 5000mah size coming? I'd like to know before I buy the 50C ones.

[TonyGagJr]

I have flown my FLRC Tigercat on the older and newer Admiral 4c 3000mah packs. There is definitely a noticeable improvement in performance with the newer packs.

New style..........Longer yes, but not as portly;). Those old fat bastards made it difficult to close battery hatches on some of my older birds.........no problem nowLOL

It's a give and take... I DID like the shorter design for the greater cg flexibility. I'm sure both perform similarly. :)

I'm sure the new ones are better, but they are also a different length. Unfortunately, I build several custom planes around the old format (6S 5000), and there is simply not room for the length of the new battery. Is there any way to get the old format? I only have one left, and if I kill that one, I have a big problem.

I have a couple that I'd sell that are in great condition if you're interested. (I too was sad to see the length inflate on the new line as it minimizes placement flexibility like you said)

Just PM me :)

I've asked the balance leads to be increased to 3". I've not yet received a response about the order in production now. It may be too late for that order but it will happen sooner or later. Thanks for the feedback everyone and keep it coming - in all areas. We really appreciate hearing from our customers.

Awesome! Thanks Tom! :)

It'll be a nice little 'convenience' upgrade to see happen in approx. 6 months.........make it happen Cap'n Tom ;)

[Alpha10]

exactly. just use as normal and you will notice better performance after about 10 flights.

I've talked to the manufacturer about 3" charge lead lengths I do want to mention the lead times are long. When I place an order, it is about 10 weeks before it is completed and then an additional 5 weeks until we receive it. Since the lead time is about 4 months, a production change today will not be seen for 4-6 months. I wish it was instant but the lead times are incredibly long.

Glad to hear... So will the leads be lengthened and this be implemented in the future? I think it'd be a great move.

Break in, in this case, just means that the batteries get a reduction in IR with the first 5-10 normal uses. So, it's kind of like the first 500 miles of a motorcycle engine, to get the parts 'familiar' with each other. If you use the batteries normally, with no abuse, then they improve a bit, and do provide a small amount of extra performance.

Hi Alpha10, I'm not sure what is happening with you pack but I'm 100% sure these are a big improvement from the old packs. I've found that most batteries do need about 10 cycles to be broken in. This was true of the old Admirals as well.

We'll see... I've never had to do that with the old Admirals, but I'm happy to say that after about 4 flights now, the packs are starting to wake up so you may be right! :)

Thanx WintrSol.............I sorta suspected that and is exactly how I treat my batts from day one - no abuse cause they aren't cheap. :Whew:

:Confused::Confused::Confused:
Got me scratching my head as well.
I usually charges 'em up and flies 'em down.
That's the way we break things in in Wyoming, be it batteries or Broncs!!

Two questions that are still hangin out there for me on this thread.............
A - are we gonna get the extra length to 3 inches on the balance lead? No interest in buying more paraphernalia in the way of lead extenders mentioned earlier. ;)
TOM - Look forward to you saying " we'll get it done" :)
B - What is this "Break In" referring to on these LiPo's ?? :Confused::Thinking:
When I think of a break-in, there is a specific protocol of disciplines to be followed say for example: racing motor RPM ranges for the first set number of hours.
My electrical engineering background can not figure any such protocol other than from my days of testing military computers to "shake n bake" (vibe/thermal cycles) standards.
ANYONE

[Alpha10]

The older (~2yo) Admirals I have did break in; I measured the IR when I first got them, then after about 4 or 5 flights, the the IR dropped about 30%. Maybe not enough to make a big difference in performance, but enough that they aren't as warm, now, as after the first flights.

I think the most you can notice is at the end of a timed flight, when you know you should only have about 20% charge left - on a landing approach, punch it hard and go around, and compare how much thrust you get. Using the T. Graphene pack, there was a visible increase in my model over an otherwise equivalent battery. The rest of the flight seemed about the same.

Good note, will do! Yes, I know the IR does improve once broken in, but as you said... That doesn't really translate into better power delivery in flight.

I'm hoping things improve, but I'd be surprised if they do as the old Admirals were consistent from day 1.

[WintrSol]

Do these new packs need to be "Broken in?" I've never had to do that with the old Admirals... Just curious.

Nuts. I was going to order more 4000 pros for the A-10. But had change of heart and ordered two 5000 late last night...

Yeah, I've been a long time Admiral promoter and supporter, but so far these just aren't much better than the HRBs... They're almost twice the price... And the extreme length makes them a bit of a PITA to use IMHO.

If they don't magically transform and start performing in the next 5 cycles I might have to kindly ask to return it and make a change. :(
