Hey,have a go Dragonfires. its not a beat your neighbour thread.
Brod..

Puff Puff.
It will work for a bit of time.
But a motor will take what it wants regardless.
I would not run that setup, Nor would any other person for that matter because of the dangers.

You run how you like lad,your simply wrong.
Paralleled lipos have been run many many times without problems.
You obviously dont know enough about electronics to realise.
Enough said on this matter.
Brod...
ps.read this thread.

One nill to Brod

are you a child? you sure act like one.

simply offering some advice to save some packs. a debate between two people and you get involoved and you bring the debate to a grade 2 level
If Brod wants to run his setup like that, By all means do, But you wont catch either me or any other FE racer doing that.

No im not but the wife tells me im like a big kid sometimes does that count ,i think he knows what hes doing mate i also read the link he posted seems the concensus on that was what Brod is doing is fine and in no way dangerous as you suggested.You came on here saying his boat wasnt running right and i disagree 100%.You stated how he was running his packs was dangerous,im not an electrical genious but ive just read that thread and i see nothing on there that supports what you are saying quite the opposite.For you to say you wont find any other fe racer running packs like Brod is doing is also a big assumption too as it seems plenty of people are running them like that wether you do it or not is up to you.

heres my though . why Parallel to diffrent compaty lipos if your only going to get the mah rated from the smallest or weckest pack . i could be wrong becouse when i tthank anout it for a min it does sound like it will work and you get the add mah . i could see it to work if you charged the seprate but chargeing the together man this is just to much to be thanking about of a early sunday morning . im already getting a headact

Good post Dragonfire! it took me about 3 reads to understand it with the spelling
Anyhow,no worries bud.All boaters together[8D]
Took the boat again today to a nearer,smaller pond,really windy,my son couldnt hold the vid.still.Too windy i think.Reckon i snagged something on the prop[>:]
Watch the spray blast across the lake.Good fun though.
Again,interior bone dry.
I'll post the vid. when i've shrunk it.

PS. the packs didnt puff
Brod..

Heres the Vid;

Hehe nice calm weather mate ,you must be brave i bet it was freezing lol.Good to see no puff too

Paralleling packs of different capacity is no problem. Even if the 2200 pack had extremely high resistance overall pack resistance will be lower. Thus, the total resistance of the packs will be lower than the pack with the least resistance. (Adding the reciprocal of each packs resistance)

Cells in parallel configuration will always be trying to balance each other out in terms of voltage. This means batteries will drain in terms of percentage and not in terms of equal individual mAh per pack.

If the Packs were wired in Series it would be a much different story but this is not the case.

If you want a nice micro Hydro to put all your Mini-v gear into try this hull, I bought one and its very nice for $57

Nice deltaforce hull, thats my review

I still need to build it...

That looks good RAY,i've got a HET2W-20 motor doin' nowt with a home made watecooled tube on it screaming for a good home.[8D]
Looks plenty of width at the back for the electrics etc..
Brod..

Bit more video today with my son in control.He did well.
Heavy crosswind,but sheltered a bit where we stood.
This boat is my most reliable i have so far.Everything comes back cool.
Just finished a 29" Cat for him with a Mega 22/30/2 on 14 cells and a X440 prop.
A very cheap esc.from China came with the boat so i had to try it.Stated a 55 amp watercooled thing.
Burnt out after about 3 mins of mid only throttle.I was 90% certain it would but tried it anyhow.
It literally blew up! i'm surprised it didnt blow the hatch off!
I have another spare CC80 i'll fit for him and watercool it.
Will post some video when i get it sorted.
We should have some fun racing our 2 boats[8D]

Make that 3 when Sams minicat comes ,she runs well mate Jack seems to like it pitty about the cat hope you get it sorted mate.By the way got a good battery off ebay for free for his cat i had a 10 quid voucher to use and it only cost a tenner so bought it oh i do love a bargain lolol.

Yours are not bargains Mart,their steals!
Something about these electrics,at least we can go to the St-Annes boat pool and run 'em there.
Sams will be well quick,run times wont be too good though.But ok.
At about 1/2--2/3 throttle,which Jack runs most of the time,i worked it out on a 10 minute run at about 23 Amps average.
These MegaMotors are good motors.
Brod...

Have to admit ive done ok so far this year with bargains ,hey just noticed that video that seagull seems to like the boat NOT!!.

The micro bat is coming to a pond near you

Well ran it today with a normal size servo that will teach me to plug batterys in the right way ,yup burnt out the mini servo.boat was running not bad till it just stopped cant find out why.Just no power getting to motor or servo yet the rx works in independant test so no probs there must be the esc?.No vissible signs of anything wrong though.Anyway heres a short video of it in some wind and a bit of chop.

Check out the turnigy esc's on Hobbycity.com I hear they run fine with inrunners. And there cheap!!

Mart,check for a 'dry' or broken solder joint on your batt-esc. connections.
Dont know how good your soldering skills are?
I used to design and build exotic valve amplifiers and i've had the occasional bad joint.
Brod..

hi mate ill have a look one thing i found before i ran was one of the connectors from the motor had come off i just heated up the solder joint and stuck the wire back in could it be that?.my soldering skills are bad,you could check it over for me if you like? you can even take it home with you and do it .Ill have one more look tonight if no good ill let you know mate.

no mart,one of the wires from the motor off wouldnt stop the built in bec work,ie the servos would still work,and i think you said yours didnt?
Check your batttery connectors again tonite.If it dosnt work.i'll pick it up later in the week when i'm passing and check it all over for you.
Brod...

hi mate checked em all and theyre fine,plugged things in again and the servo wasnt moving nor the motor then noticed a smell the esc was smoking unplugged it and removed battery and the battery was swolen up and very hot.all this happened withing just a few seconds?.battery seems fine now,i tested it on a spare brushed motor direct.the esc must have been faulty?.

Yup,sounds like the esc's toast[X(]
be careful now with that battery,once they puff,they'll do it again very easy.
A lipo fire is no joke,once they ignite,they are like a firework.
bad luck..
