Well just about the time I think that the tone around here might be shifting to a more civil one, you pop up with a post slamming one of the best RC equipment suppliers around and I doubt you've ever even done business with WrongWay RC.

I have done business with Steve (NoBS) and he does good work but he's more expensive than other options like WrongWay or Taildragger who by the way for rcflip, picked up Kurt's battery business when he gave up on Fromeco.

Thankyou for the information Zeeb but I gave up on A123 a long time ago as well.

I have had friends send me other brand packs in the past and when the covering came off... the spot weld was loose.(please remember my original post where I noted it was rare) Most of them were two years in use or so. This is why I choose my method where the wires are PERMANENTLY attached to the cells.
Y'all have a nice day.

Well excuse me Zeeb. I did not realize that this thread was a WrongWay RC advertisement. I apologize for offending you and your buddy.

You're not excused. Your post about a spot welder and this "apology" are both offensive as neither one is true. Why don't you crawl back in your hole as it seems from your post count, that is what you do most of the time and not bother the adults anymore?

I used to solder my own NIMH packs in my rc racing days it is easy peasy, a jig makes assembly easier as well. Cheap packs were spot welded, the good race packs needed assembly.

A lot of guys read these threads trying to find information. They don't realize that they are actually tag team marketing campaigns. Sure, I have soldered battery packs together for 40 years. That is because I don't have a spot welder. My records show that I bought a 2S 2500 A123 pack from WrongWay RC in 2012 because he was the first to sell them. This was the most amateurish assembly that I have ever seen. A huge blob of solder covering both ends of each cell. The reason that the manufacturer does not recommend soldering is BECAUSE IT DAMAGES THE CELLS.

If you can't spot weld or are too cheap to buy a spot welder you can buy A123 cells from the factory with spot welds that you could never vibrate off.

Now I will get off of Zeeb's personal thread and crawl back under my rock.

I have in my hand an old 1100 at least 5 or six years old from Wrong Way. I managed to leave my switch on and ran it down to 0. I cut the cover off just out of curiosity and the cells have spot welded tabs with four spots. The ones I used to harvest from B&D drill packs have only two spots and I had one come loose while soldering to it. He had done a clean job of soldering the center balance lead to the strap joining the batteries. He has all wires soldered to tabs covered with shrink and another shrink at wires exiting the cells. I stopped doing my own packs after seeing this . I now hear that he is now going directly to the cells with some type of propriety bond. All of my 2300 and 2500 are still in service so I have not opened one of them. I ordered a couple of packs a few years ago and asked him to not put connectors on the output leads. His response was he had to put connectors on because he cycle tests before shipment. This is a quality guy to do business with.

I've had very good success with the Electrodynamics A123 packs in three different IMAC planes. Two of which are 40% or larger Carden Pro's. The packs are professionally assembled using a specialized spot welding machine made just for this purpose (I have actually seen it). What is really great about the company is that they will custom make a pack for your particular setup. Since I run two seperate Rx's in my larger planes, I have Electrodynamics make a single pack that encases two 2s packs for ease of removal and use. I now have well over 6 years of sequence flying using this setup. Very pleased with the battery construction.
Here's an article that explains further that I posted earlier. http://www.mini-iac.org/Regions/North-Central-Region

One of the services that Wrong Way does is he will put what ever lead lengths you want with whatever connectors you need and he uses mini-deans for the charge leads if you want which can take higher charging loads, I charge at 10 amps. No relationship other than a happy customer.

Or you can just buy the cells with a soldering tab already spot welded on.
Hobby King has them for 11.00 bucks a cell.

Interesting. I was not aware Hobby King carried genuine A123 cells.

With HK I would not bet on them even being genuine let alone grade A cells if they are....
