Best PSU for Power Lab 8 ??

[1heli]

Hello Everyone,
I am 99% convinced that when I do eventually end up flying RC Heli.
hopefully a LOGO 600SE with DJI.I will go for the powerlab 8 would this be a good and sensible choice?

if so what PSU is considered the best to partner it?
must add I will only ever be flying the ONE Rc heli (for good rational reasons) so everything must be geared to the one Heli.

and because I am only ever going to fly(fingers crossed) the one heli then it should have the best of everything,from batteries to servos and everything in between.

I do not wish to bore you guys to much but for reasons medical there will not be any thought of (3D or aerobatics?) again logical reasons for this to.
I am trying to achieve something here which if sucsessful will be more wonderful than I could express..and my learning curve as to be faster than would be normally advised?

therfore I would be more than happy to be able to hover at all positions..and do circuits...why something like the Lego 600se well I was told any of these top Heli`s can be tamed down a bit to all ow someone like me the luxury of flying what would normally be the preserve of the serious flyers...and that goes for similar heli`s to the LOGO 600.

so really it is charger/Balancer & PSU choice...

many thanks in advance

Steve

I use dual deep cycles for fast field charging or a 42A feathermerchant PSU for charging at home.

Best or cheapest ? Best i would say a meanwell, cheapest i would say the link above.

those supplies only give you up to 1128 watts
if you dont charge more than a 6s pack your ok
the pl8 can actually pull as much as 1344watts

if your not going above a 6s pack the pl6 is probably a better bet for you unless you want the higher discharge rate

also the pl8 seems to perform better on 27-30v supply

this is what I use

https://www.helifreak.com/attachment...0&d=1333073248

I have modified the voltage I know have a 27.8v output and with the fan mod I can adjust the fan speed so that its almost completely un-heard or a typhoon. I leave it set to un-heard

27.8v at 112.5a = 3127.5 watts
you'll never use that much but it can do it

these supplies will also work on 110 or 220ac

That depends on how you determine "best". In terms of build quality, I would say the HP server units blow the MW units out of the water. I will admit the MW units are easier to use/connect to.

What brand supply is that? where did you get it?

[DominicD]

You know what is funny ? I went back and forth about going with the 1000i vs 2000i, and until I got my 90e the 1000i i bought seemed like the right choice .... now I am not so sure.

Hi DomicD, satgod, TJinGuy(enjoy your web page)

Many thanks for your very helpful replies even since writing the original thread starter things have moved on and it will definately be the PL6 +MPA and I have received a few comments re PSUs and more than one mentioning the Meanwell which whilst good, I am reliably informed..was not made with RC in mind so maybe better going for something like the JUNSI 1200/Chargery 1200(maybe same as Junsi 1200?) not sure. was advised to read a review which I have not got around to as yet.

I would say the HP server units blow the MW units out of the water.

sorry but what are HP server units presumably hewlett packard am I correct?

satgod

if your not going above a 6s pack the pl6 is probably a better bet for you unless you want the higher discharge rate
also the pl8 seems to perform better on 27-30v supply

Please can I ask would the reasons justify alone going for the PL8?

I am still trying hard to get my head around the charging routine and electrical terminology e.t.c. but it`s getting there slowly

Best wishes Steve

[DominicD]

The MPA is fantastic, this was my first time using it

[TJinGuy]

Yes HP stands for Hewlett Packard. Feathermerchant sells them as his 47A 12V units. They are these

I may not fully or even partially understand a lot of things re Rc Heli`s and Lipos & Chargers but I know one thing Power Lab/MPA seems superb on several fronts many thanks for the pic really helps me

cheers Steve

[1heli]

You are one really clever guy and I take my hat off to you..but I would not even contemplate doing the things you do...the HP units look good and seem to work well

all the best Steve

I agree.. comparing any end-user MW PS and a DPS-600PB is the same as comparing a Chevrolet Cruze and a BWM series 7 (this last one being the DPS-600, )

Best Regards

that is 2 jd200 12v power supplies connected in series give me my power

I did a voltage mod so they now output a total of 27.8v
I also did a fan mod so they are dead quite

Wow 1570 watts at 12v, how did you mod it to 27.8v? How are they holding up? how long in use?

everything in that power supply is adjustable via resitor packs

holding up like a champ. I actually have a couple of these that have been in use for over a year. I sell them to guys that use them for ham radio and cb's all the time.
They love the power because they use high power leniers to get much greater rang and ussually need 800-1200 watt supplies to do it

Not impressed with the PL8 so far and the whole parallel charging trend.
Accurate Charge takes forever, high power leaves the cells unbalanced.
Coming from a super duo 3, which balances perfectly.
I checked the packs after charge on the PL8 on a cell tester and some cells .6V out of balance

First that I have heard of this. I have two PL6's. I charge 4 3s batts at 2C (4.40A).
They charge in about 20min, and come out perfectly balanced. Remember the battery tester has a +/- accuracy. I just checked two batts that came off the charger.
my $25 testse shows: 4.18 - 4.18 - 4.17
My $6 cheapie tester shows 4.20 - 4.20 - 4.18
The PL6 shows 4.19 - 4.19 - 4.19
I would tent to believe the $175 charger is a touch more accurate. But either way, the cells are balanced.

Question: Unless you use a high charge preset, the internal settings limits you to a total of 10 amps. So even though you might select 4 batts at 4 amps, you will only get a total of 10amps (not 16a) which is for all four batts.

Maybe your settings are not correct.

[satgod]

if your not planing on charging anything bigger than 6s get the pl-6

UNLESS you want a higher discharge rate in which case get the pl-8

you have to go into the settings on the charger and raise the current limit its set to a lower limit from the factory and then you can charge wide open

I have charge 4 6s 3300mah packs in about 13-17 minutes and thats not a max current

Ya that will last maybe a season then...
The addiction takes over.

Sounds like good rational to me, always run the best gear you can afford.

I told myself the same this time 4yrs ago and once you get past one hurdle you move on to concur the next.
After a work related injury I am now a C6 Quadriplegic with zero hand function and now in my 4th season flying I am into some 3D stuff.
If you want to do it you'll find a way.
Logo is a nice machine but pricey to repair after a crash, and you will crash.

Not sure what I'd pick today as a first heli but would be at least a 500 size FBL. My first was a Thunder Tiger E550 and it was tough.
My buddies Trex 550 seems to be holding up well but doesn't fair well in a crash.

so really it is charger/Balancer & PSU choice...

PL8 looks good, will be trying one soon. I am going to pair it with this PSU

For the most part I charge off two Deep Cycles but if I want to pre charge at home it should do the job.


Steve

Good Luck.
