I like your new avatar? When you told me the GF was a bitch I had a different picture in my mind.... But its all good, whatever floats your boat Nitrosucker.

:rofl::rofl:

I like the name pimp-power though. Your motto could be "pimp-power lipo, like a bitch slap for your truck"

LOL nah thats my dog, Ratchet. He's a bastard with a tool name... :lol:



Thats kinda what I was thinking... Or maybe "Pimp-power, any other is just a hoe."

Hey linc, got the zippy h thanks! Helluva nice job putting it back together and great packaging for the trip here.

Ah, see the true on this pack is that I supervised and made some managerial decision to help linc better his lipo repair service.

:na: nah, but I did watch him make this one up.

Funny, cute dog too, does he piss everywhere or have you trained him to stick to peoples legs and car tires?

Heres a few:

Pimp-Power, straight off the corner and in your pants!

Pimp-Power, black is nice! (referring to the color of the shrink wrap)

Pimp-Power, anything less is uncivilized!

Pimp-Power, wheres the beef?

Pimp-Power, expect the best, you deserve it!

Pimp-Power, we got dis lipo s%^t on lock, ya heard!

Pimp-Power, right near the beach, boiiiiii!

No prob, glad you like it!

Yeah, like you watched me put the main lead on backwards and then saw me scratching my head when the balance tap would not register on the cell checker... That was a bit funny, at least I noticed before I sent it to Texas!

I plugged it up and it worked so I guess all is well..... :neutral:

Yeah, I had the pos and neg balance wires swapped when I put it together... No matter what I did I could not make the lipo checker work, so I broke out the trusty multimeter and saw the problem immediately. It was probably cause nitrolover was talking and breaking my concentration:lol:

O sure, blame it on me. Just because I was there watching, being peaceful and talking about hoes, I get blamed... lol

Texas dont worry about him...

More like talking about dudes, you were about to make me sick with that. Don't ask don't tell buddy.

To pull this thread back on topic. I have a Zippy lipo which I bought a while back and have yet to use, just whacked it on the charger to see what's up and one of the cells is does not look too good.

1.02v
3.81v
3.80v
3.81v
3.81v

It is a 5S 4000mah. Is there a way to resurrect the flat cell? What is the recommended procedure?

Oh jeez... Is it puffed?

Isolate the cell and slowly charge it. Not sure what charger you have, but A carefully watched nimh charger usually works well. Charge at a low rate, like .3amp until the voltage gets up to 3v or so. Then swap back to a lipo charge until it gets to around 3.8v. Then charge the pack as you normally would and balance it at the same time. Let it sit for a day or so and then check the cell voltages. If the bad cell is loosing voltage you may want to trash or reconfig the pack.

Cool thanks for the advice.

The pack does not look puffed, or any different to the 3 others that I have (all fine).

I will try and isolate the pack and do a nimh charge. I have a Hyperion 0610i charger. Is there a way to charge it using the balance taps? Or do I have to open up the packaging to get at it.

You can charge thru the balance taps, but not over 1 amp as the wires are a bit thin. Just find the 2 wires, pos and neg that go to that cell, use a multi meter to figure that out. Ten either use a female tap with wires to attach to the charger or unplug the 2 wires from the tap and use alligator clips, be careful not to touch them together.

Alright no problems, I have the needed connections and wires, so will give it a shot tonight.

If the cell doesn't work out, I will probably end up sending it to you to deal with like last time.

No pob, hope you have good luck with it, just do not leave it unattended while you try to restore it...

Here a quick pic of some lipos I just finished. The 4 on the lest are a broken up 10s pack- 2 2s and 23s packs. The other 2 were packs with one damaged cell that I removed.

Linc-
My buddy made me a parallel adapter. I hooked up one side to my MMM. It turned on. It was nice. I unplugged the battery and plugged it into the other side. *poof* Magic smoke. The adapter was mis-wired. Thankfully (don't know how) the MMM survived. The smoke came from the battery pack. I assume a main pack lead burnt, or atleast cooked a little. No swelling. I haven't volt metered it or anything, It just scares me now. Even if I open it up and find (or don't find) a problem I don't have the stuff or ability to reshrink it. I think it desires to be stripped and man handled by you. PM me your addy if you're up for another lipo repair.

It's a 15c 6s 5000mah flightmax. Slightly cooked.....

Just check voltage on the cells and everything- if it checks out then your good to go- no repair needed...

I think you just want linc to manhandle your junk :lol:

smoke came out. even if it's "good" I don't trust the solder joints anymore. It needs to be opened and inspected. Once opened, I don't have shrinkwrap, a heatgun, or desire to shrinkwrap a pack. I have the worst f'ing luck with this stuff. Dozens of trucks and thousands of dollars spent and maybe an hour runtime...................................... Frick!

And you're right about the last part........

Linc-


Post #339^^^. Read please. :intello:

Liiiiiiiinnnnnnnnnccccccccc? Helllllloooooooooo:eyes:

Lincy Poo?

I think Lincy poo went night nighty for a long time.. :sleep:

:rofl:

Everyone's a comedian... Wonder how long you sat thinking that one up rawbuns?

H-Bag, sent you a pm...

Oooooh, a few weeks.
You know, the usual...
:rofl::yipi:

Wow, Linc must get realllllly tired of me :yes:

Nah, any humor is welcome here, even it it is a bit "unrefined" (bad).

Keep it up rawpits, you will get there!!!!

:lol:

My comebacks are prettybad..... :whip: :oops:

Silly green pimps and their AK's... :no:

I will bust a cap in you azz... rawfarts... Do mess wit da green, my frog homies will be knockin you door down...

I dead shorted two packs. Moral of the story? Check other peoples work before allowing them to plug it in. Or take over if it's your stuff and plug it in yourself, then you can inspect it before anything happens.

Just to be clear my friend did this, noboody here. He does all my soldering for free. Can I be mad at him when shit happens?:neutral:

........:oh::lol:

I'll just green screen you!

I have no clue, don't ask, I know that didn't make any sense.. at all... :neutral:

hey linc you ever do anything with that battery i let you keep, the true rc one.

hey linc can you help me with A protek 4s starter box pack? seems like 1 cell has gone bad pm me your info so i can mail to you its not puffed at all

Hey Linc, do you have any experience with A123's?
I have 5 2s2p packs I'd like reconfigured into 2 10s1p packs. I've got all the taps,bars,wire and shrink I'll send along with.They would be sidexside config.(i was gonna do em' but not confident in soldering aluminum)

Also I have a Zippy 5s with 1 cell I can't get to balance with the rest I keep getting
4.2 on 4 cells and 3.85 on the other. I think I'd like this and another just like it redone to 4s packs.

And last I have 2 ThunderPower 5s packs that take a good amount of Mah. but have no punch. If you could have a look at them see whats up,if they're pooched so be it.
thanks

i have a 5s 3700 pack that looks and feels and chargesnormal. But makes no power at all. acts like a dead 4s pack would with same gearing. soldered a new deans on it just to make sure but no difference.

Is it in balance? How old is it and what mfg,c rating, etc?

Linc, I have (2) Rhino 5s 4900's, and (2) Rhino 3s 4900's. Interested in reconfiguring these to (4) 4s packs?

I'll be running the 2200 on 4s in both 8T and 8B and 4s seems to be prime in both.

always been in balance. always used hyperion duo charger. got the pack from mike .its a enerland. only thing is the cells are a little squished on the end where it hits the end of the battery tray.

my guess is 2 years old? its twin pack i got at same time is still perfect. i use them maybe 5 charges a week?

Hmm, the squished end may be causing the issue. If you have had that much use out of the lipo you are doing pretty good. 5 charges a week for 2 years is around 500 cycles...
