RE: 6S 10A 250W charger/discharger(106B+)
That's the 1010 charger...the 106 charger's page doesn't show a balance board like that and it's not listed as "included." So even though it seems like it should come with a balance board, it's not clear that it does. Thanks for pointing that out though. [8D] I'm kind of hoping that someone here has used the 106b+ and can give some advice. [&:] It kind of looks like the 106B+ has several balancing ports in the side, like for 2s-6s, so that pack plugs right into it. Whereas the 1010B+ didn't have room for 2s-10s ports on the side, so they just did one port and connected a balancing board to it. That still leaves the question...what balance tap type for the 106B+?

RE: 6S 10A 250W charger/discharger(106B+)
Bump again...still wondering about the 106b+! Does it come with some sort of balance board to plug into the side? Or does the pack's balance tap plug directly into the side of the charger? Either way, what type of balance connector does the charger use? I need to know this if I am ever to buy this charger! [8D]

Bump...still curious about balancing taps with this charger. Can you plug a pack's balance tap straight into the side of the charger? If so, what type of balance tap is the charger compatible with? Or do you need to buy a separate adapter board like I have seen on a couple websites?

RE: A123 QUESTIONS
Jeff, good to hear your testimony since I might end up going 2s1p in my Stampede, and I might want to gear up to compensate for lower voltage...but I don't want to lose my wheelies either. Is that a 3s1p pack you fly in your heli? Cause 3s2p would be enormous...but I don't have a good sense of how big those birds are.

RE: Super Brain 977 and A123
[quote]ORIGINAL: Barber420 If I read the information correctly...[&:] my 977 should charge A123 just fine. The "Dapter" sold at SinCityJets says it's to convert any NiCd charger into a Lipo/A123 charger. I would assume since the "Dapter" converts it to charge either, that any charger that can already charge Lipo can charge A123? Am I correct? [/quote] Not quite correct, no. Many LiPo chargers can charge A123 in a sense, but that's only because A123 cells are very tolerant of overcharging. The fact of the matter is that A123's have different charging parameters than LiPo (namely, a lower nominal and fully-charged voltage). Your 977 was not designed with A123's in mind. For best results in my opinion you'll want to get a Dapter. And if you haven't figured it out already....no, A123 does not require a low voltage cutoff.

RE: Rookie to electric R/CNeed Help?
Did you mean 1100 mAh capacity? Is this a main battery pack for a car or an airplane pack or what? Generally for lower capacity NiMH cells like that, stick to a charge rate of maybe 1 or 2 amps (max). Someone else can be more specific possibly. I charge my GP3300 car packs at a full 5 amps and it's fine for them, but smaller cells like yours don't like to be charged that fast. 7.2 volts is the nominal voltage rating for your battery pack. A fully-charged battery will actually have higher voltage than its rated voltage. Additionally, when the charger is forcing current into the battery pack during the charge process it "sees" a higher voltage than the pack will actually be at when you take it off the charger. 10 volts still seems a bit high, though. I'd expect more like 8.5 to 9.0 volts for a 7.2v pack (or thereabouts). When you take the pack off the charger and measure the pack voltage with a meter, it will show lower than what the charger said. Another thing to consider is the peak threshold. This is the voltage drop that the charger looks for before it stops the charge. As a battery is fully charged the voltage actually drops slightly, which the charger can sense. If you set the peak threshold too high, though, the charger can overcharge the battery. This could be the reason why your pack reaches around 10 volts during charging. Your charger may do it automatically, I don't know about that one. But check for the peak threshold setting, and make sure it is set to 5mV OR LESS per cell. That will be good for NiMH.

These projects are great! Hey snellemin, you have a lucky son! What is your "good charger" going to be? I tell you, if 2s2p A123 fit in my Stampede I would go A123 so fast. Lower capacity of the 2s1p is the ONLY thing holding me back at this point. Still, I will probably go A123 eventually. How long have I been lurking on this forum without owning A123? [:D]

RE: 2s and 3s a123 cells in my traxxas rustler and stampede
Good to hear that the 2s does well with such a powerful motor. I think a lot of people are turned off by the lower nominal voltage of A123's, thinking they aren't up to the task (admittedly I have had similar thoughts myself while researching batteries). If you daughter's truck has the Traxxas "Stinger" motor, it is a 20 turn motor just FYI. It's probably not much faster than a good 27 turn motor though.

RE: 1/10 car application
Thanks for the info guys. Being a basher I do wish I could get some more run time out of A123 cells (2s2p pack would be fine for me if it weren't for the huge size). But I may yet go the A123 route for the fast charging and such. Run time claims for the 2s1p packs seem to really vary. Just within this thread there is a big range. mattnin - I'm not so sure mixing 2 different types/capacities of A123 cells together in one pack is such a good idea..??

RE: 1/10 car application
[quote]ORIGINAL: enter801 They do have 7.2v LiFe packs, called Hypersonic Turbo packs. They are pretty sweet, they are variable voltage. They go from 7.2v to 10.8v with a switch they have on them. They are 2s2p packs. Only bad thing is they are $189, however you get the voltage u need. Check em out - [link]http://www.a123racing.com/html/hypersonicturbo.html[/link] [/quote] It's actually a separate "turbo module" that steps up the voltage and can be used on any A123 pack. They are just packaged together in this case. However, it is not recommended for use with high-powered motors such as brushless setups. FDR stands for Final Drive Ratio. It's basically the ratio of the number of turns of the motor armature for each turn of the car's wheels.

RE: e-revo and 4600mah a123s run time ?
I think technically an A123 pack is 1mm too thick for the E-Revo battery boxes. This is just according to the specs for the two products. I haven't heard if they can be "persuaded" to fit. Hopefully someone has an answer, but you might have to check another section of the forum that has more traffic and more E-Revo users. Be sure to let us know what you find out though.

RE: 1/10 car application
The Hypersonic charger charges at 10 amps, so that's what you'll need (as a minimum) for a power supply. Obviously a little headroom is not a bad idea. While we're talking chargers, I've stumbled across the iCharger 106b which can be had for $100. That's a bit more than the Hypersonic, but it still charges at 10 amps and can do LiPo's, and it still balances. So it is more versatile than the A123 charger. You'd have to make sure your ordered A123 packs from someplace that could put the correct balance taps on them though.

I sure hope A123 continues to explore the RC market. The recent Enerland stuff is promising, and they're still running ads in the RC magazine I get. The problem is there is no substance to this stuff. Detailed info is hard to find, as are the products themselves. The 1100-mAh cells have been advertised in finished pack form for months, but cannot be purchased anywhere. I really hope A123 remedies this stuff and continues to push their RC products, because it is really promising technology.
