I would like to know if someone has had this problem.
I bought a Fromeco Battery (Peeless 2400 MAH). After few flies the Battery died and I sent it to Fromeco in that way they could find why did this happened.
I was told that it was a dead battery. At that time I did not mind and I repair the helicopter and a new battery (Allegedly) was sent to me.
Today I was going to my third fly and as always I check the battery it read 7.50 more than enough for one more fly.
I was in forward fly when the helicopter turned to me and almost hit me. After the crash I check the battery and again it was dead.
Please see the pictures.
I am posting this in case someone had the same problem and who ever has this batteries please watch out.
I couldn't say that is an isolated case because this is the second time it happened it. Or the battery I sent to Fromeco was not exchange and it was charged again and sent back to me. I do not want to believe the last part.

i've had fromecos for about 4 years now and always been fine so i can't say i've heard or came across this problem. infact my original fromeco still works after all this time.

i find it real hard to swallow you managed to get a pair of dead batteries and you hear good things about their customer service over there in USA so i doubt they would send you the same battery back. if you look at the pack it should have a born on date, does that match the one you had before?

given the odds of getting a pair of batteries that have exactly the same faults must be huge i would start looking at the heli as it looks like if it is dead then it's shorting out.

let us know how you get on.

cheers

Things to look for...
- Short circuits
- Servos that are binding...
- Are you sure that everything is 100% safe about battery, regulator... connectivity...
- What about the charging process...

I'm using a 4800mah peerless one... never had such an issue...

What is your point regarding the picture? The battery appears to have crash damage. The crash may have killed the battery.

I have had ZERO issues running Fromeco products for the past 4 seasons.

What charger are you using to charge them? What was the voltage of the pack after charging?

Is your reg up to the task? I see you're using a duralite reg. Have you had that checked out? As mentioned earlier are your servos binding/ stalling?

I seem to remember a thread or two about Duralite regulators not being able to "handle" Peerless batteries. Sounds crazy, I know, but it happened to multiple people and was eventually confirmed on the bench. Something about the Fromeco batteries could maintain a higher voltage under load which meant more heat for the regulator to desipate. That's what I remember, anyways.

If I'm off my rocker and just plain wrong, I apologize. I'm doing searches trying to find it now. Anyone else remember this?

I did say that I do not want to believe that it was the same pack, but I do understand that happened once, but not twice. And yes it has a different born day and this was not the first fly with it.I had JR Nicad Battery before and I did not have any problems
And the surprising part is that I got 7.50 before taking off.
The battery does not have any damage from the crash, what you see in the picture is the glue from the velcro tape.

AE could it be that the pc board inside tha battery pack got fryed?
also,if you could,get a volt meter and use a neddle point probe to test the pack,this would rule out the battery being completely dead and or any shorts in the wires,

check the voltage through the deans connector before doing the above,sorry about your crashes man,that really sucks,better luck in the future

this hapened to me too with aTroybuilt models battery after the second fly went dead

Im almost 100% sure they are the same with different label when I called T.B. they told me that they already knew about the problem with the batteries going dead, but they still selling them I will never buy anything from them again, from now on I only use lipos

helilab, there more chance of a lipo failing than a li-ion but each to their own. i wouldn't like to crash hard with any lipo onboard as i have the luck of the irish.

this battery has shorted out imo.

the duralitte reg i don't know about.

keep us informed what you find out.

cheers

It's either the battery or the regulator. Bench test both of them (separately and together) and see what happens. I use a CBA-II for
battery testing.

My flying buddies 600N fell out of the sky today at a fun-fly after the voltage dropped right out on a 6 month old Peerless 2400. Battery appears to be completely dead.

alright barney, what happened, what was the flying voltage, what regulator?

how do you know the battery is now completely dead?

does the regulator work with another battery?

ALL my machines have fromecos and i want to know if there is something in this.

cheers

p.s hows the gyro?

It's a Fromeco peerless with a Fremoco Arizona..His heli started up etc as per normal took off and he felt something was not right so landed checked all controls etc All looked good lifted off.. about 30-40 secs into flight it all went dead mid flight about 30ft up...he had enough time to Waggle everything and hit hold before it went in.

It landed quite softly ..Boom, TT and blade grip + front TT gear and battered the canopy a bit.

Everything was dead. Arizona had no blue lights on either so checked battery V.. both on the check lead and on the battery to Reg connecter..0.00 V

It's not done a lot maybe 100 cycles tops. It's never been decked either. The Peerless has a small PCB on the bottom under the heatshrink..as it's under warranty we don't want to open it all up but that would be my first guess. It is completely un-marked otherwise.

I'll hear back from Ian later to see if there is any wiring faults but it appeared all to be OK on initial look for the rest of the radio.

if it is zero volts then i can only assume the battery is shorting out. wether thats the pcb board or not i guess realraptors would have to sort that one out when they check the battery.

I got 7.50 before taking off
Funny, I see that same voltage posted here and resulted in a crash.
At that voltage with 15 minutes of flying with all digital servos, 7.5 volts CURRENT is definitely not up to par.

I use the Fromeco battery with a Duralite 5.1v regulator for 2 years now with no problem. I charge the battery with a Duralite slow charger and never with a Fast charger.

that doesn't mean it should be 0 volts when it takes a dump. fromeco say 7v under 1 amp load is cut off so well within it for a normal flight.

You can go with all the documents that support their theory. But after many incidents I have seen and heard, I would stop flying at 7.6v to keep my expensive fleet from being thrashed.

i never said fly it that low but if what the makers say is 7v and the one above was at 7.5 then i would be more than happy with that. my own fleet i never go below 7.5 but thats just me and it's just thats what my batts are the one time i've seen it that low.
