Status: offline 		What kind of problems? Word on the Internet is, A123 can be rather hard to get a hold of. I've been buying Dewalt 36 Volt batteries, and pulling the cells out of them. I believe the part number is DC9360, from ebay. www.battlepack.com also has these batteries for sale.

Check with wattflyer/everydayflyer. This guy has a LOT of experience with the A123 batteries.

I've got a few of these, a pair of 6S2P A123 packs that pull 57 amps full throttle, one 5S2P also pulls 57 amps full throttle, and two 4S1P packs that pull about 30 amps full throttle. All have been performing very well, this is the second year on them.

Search for "a123" in www.wattflyer.com. You will find a lot of information there.

Status: offline 		Well I did not want to say much on here but I bought 6 new 6.6v packs and three of them are in the 3 and 2volt range.I cannot get them to come up.In there directions it states if voltage is lower than 3volt per cell to contact them at customersupport@A123racing.com but this does not work and neither does there web site.I tried starting a charge on the one pack and setting it for 1s.It took 3 amp and says it was charged?There are some cell issues.The three other packs are all fine.This is my first time with A123 .I have only ran Lipoly ,Nicad and Nimh cells .I have never had any problems with batteriel over a 30 plus year period until these.

Status: offline 		Have you tried just charging the low cells to get them above 3V? Or possibly even using a zip charge to kind of jump start them? One of my 3s packs came the same way, it was 2.6v on one cell and my charger wouldn't charge the pack because it thought the pack was bad. I was able to get the low cell up above 3v using a zip line then was able to charge the pack on my charger and have used it about 30 or so cycles and have never had problems since.

I hope this doesn't give you a bad taste for A123 batteries, they truly are great cells and are quite durable.

Status: offline 		These are a premade Hypersonic packs, 2s2p 4600.I do not want to cut into them or anything like that until I can make some contact with someone about warranty.I did charge them at 1s 3.6v and it went up in vlts but only took 3mah and then the charger shut down saying charge complete.It was down to 2.11v in a minute or so.This is total pack voltage and not 1 cell.
And as for a bad taste ,It is more a Ebay store bad taste as I am still awaiting reply and hopfully another (good) pack from this online store(shorted me 1 pack).I am really tired of our sell ,but do not backing anything up system.I have been running TrakPower lipo's and the one thing that was great is they told the hobby store that they could warranty any problems with packs.I never had to use this but it is comforting.And yes I have no idea why I am trying something different since the TrakPowers have worked well for me for almost 2 years.Thanks

Status: offline 		You don't need to cut the packs open. Mine are the Hypersonics too and I didn't cut the packs open at all. You won't be able to zip charge with your charger. Do a search for zip charging, you will need some type of watt meter though.

I bought mine off E-bay too, from what I've heard a lot of the E-Bay packs are old inventory and are drained pretty low.

Like I said before, don't give up yet the A123 packs are great, the 8 minute charge times are nice.

Status: offline 		I am sorry if I am wrong but you are saying to try and charge just the low cells and I do not understand how you would do that without cutting open the packs? Thanks ad I will look at zip charging.Dennis

?? Don't understand charge them at 3.6 Volts. These cells are to be charged to 3.6 VDC per cell, making your 2S2P charge voltage to be 7.2 VDC. If you are charging both series cells at 3.6 VDC, your charger will indead shut down real quick.

Nominal voltage of two series A123 cells will be around 6.6 VDC, if they have been off of the charger for a few weeks or so.

Yes but when you only have 2.1volts in your 6.6v pack you charger will not let you charge.It will tell you voltage to low.So I put it on 1s to try and bring the voltage up some.How else do you think I should try and get it up.I do understand that the pack is 6.6v but if it won't charge tell me what else to try.I was just trying things.

Status: offline 		Hello Guys I may have the problem solved as long as the packs perform OK.I hooked up the 2.11v pack(6.6v) to my Older LRP Quantum charger and hit it with 8 amps .This is a Nim and Nicad charger only but does not care about a low voltage.I only charge until the voltage came up slightly over 6v and had put just under 200mah into it.Then I stuck it onto the Lith Ion profile charger,away it went charging fine so far.
So Zeta30 I did not get around to the Zip charging but I found a quick way to get it all going .Thanks

Status: offline 		I just bought 2 of the 6.6v packs and one of mine came in at only 3.1v, but the hypersonic charger did charge it and the pack worked good. I am happy with them so far, got em on ebay also. I got 2 9.9v packs too and those both came with 9v or so out of the package. I emailed the seller and he did reply to me about these low voltage packs. I told him that mine was only 3 and the instructions said this means something is wrong and I was afraid to charge it. He told me some have been that way and it was safe to charge..... Has anyone lost any of these cells to low voltage yet?

Status: offline 		Glad I found this thread. I just bought four and got one free of the 6.6v, 4600mah packs. Three were low in voltage. Average about 4 volts per pack. I just read under 6volts is a problem. I went ahead and put one on the charger and hit it with 5 amps. Seems to be charging. After 13 minutes, it's put in 1,146mah. (It's still on the charger) Does that sound about right?
