    PACK DIMENSIONS: 138.5mm long x 46mm wide x 24.5mm deep

    It's a standard 2S hardcase size. It will fit.
    Is the 70C strictly needed in a brushed Summit? No. Is it a waste? No. Greater C-rating = less voltage drop and less stress on the pack. Also, those of us who also have brushless trucks, especially the big ones, will have one pack to use across the platforms.

    This battery is 2.5mm wider and 2mm taller. Also it's a hardcase battery, I'm not sure...

    That balancer permits you charge 4 baterys balanced? What brand and model is that balancer? please link it...

    The charger is not what allows you to charge 4 or 6 batteries. Is the parallel charging board that does. However, with 8K-class lipos, you need alot of amps to charge them at the recommended rate (1C). To charge those 4 SPCs8200s at 1C, you would need 32.8 amps, not many chargers out there can deliver that. The 206B is a great charger, but its max output is 20amps. It can charge those 4 or even 6 batts, but because you are not charging at 1C your charge times will increase. I use the same setup as bwill11, when I parallel charge two 8200s it takes about 30-35mins (from storage voltage). I've never hooked up 4 or 6 but I am wondering how long it takes to charge them? bwill11?

    Just recieved this set up for my birthday. At the time of the pic I was charging all four from storage voltage, then discharging back to storage just to get a cycle on them. Fairly fast from storage to peak voltage, about 5 hours from peak to storage. I had the amps set very low for storage though. I figured i didn't need the thirty (306b) amp charger, because I will only be charging two batteries at a time normally. From cut-off voltage, I expect charge time about 60-70 min for all four. Just a guess though. All my speeds controls are at Traxxas right now. Getting two upgraded to LVC and 1 LVC is getting repaired/warrantied. So no use of super cool new batteries or charging station . targetingxmod go here http://www.progressiverc.com/the-ste...00w-combo.html i figured it was the cheapest way to charge more than one high capacity Lipo.

    2 8200's from LVC to full: ~35 minutes
    2 8200's from storage to full: ~17 minutes

    3 8200's from LVC to full: ~52 minutes

    6 8200's from LVC to full: ~104 minutes
    6 8200's from storage to full: ~52 minutes


    All being balance charged at 20 amps with an iCharger 206B being fed 24 volts.
    I have created an Excel spreadsheet that calculates this for me... it is not 100% accurate due to the balance process, but it gives a very close approximation. The formulas take into account the efficiency of the charger (90%+ for iChargers), state of discharge, amperage, C rate, cell count, % of discharge, cost to charge... pretty much everything but how far out of balance the cells are.


    Just a little more info...
    COST to charge:
    2 8200's from LVC to full: ~.016¢
    2 8200's from storage to full: ~.008¢

    3 8200's from LVC to full: ~.025¢
    3 8200's from storage to full: ~.012¢

    4 8200's from LVC to full: ~.033¢
    4 8200's from storage to full: ~.016¢

    5 8200's from LVC to full: ~.042¢
    5 8200's from storage to full: ~.021¢

    6 8200's from LVC to full: ~.050¢
    6 8200's from storage to full: ~.025¢

    This cost will vary based on your location due to fluctuations in the cost of electricity.
    Whatever it is I just said... I could be wrong.

    My guess for a four battery charge time was pretty accurate- Thanks for that ego boost Jimmy . It's killing me right now to not have a running truck. Poor planning on my part.

    No problem!
    Traxxas is usually pretty quick with the turn-around... you should be back to RC'n in no time.

    Also, discharging can be done quicker with regenerative discharging or adding an external in-line load with the iCharger... I have not looked any further than that though, so that is all the knowledge I can give.
    I ended up building a separate stand-alone discharger to run my batteries down when needed...

    Awesome! Thanks for sharing that.
    Overall I'm very happy with the 206B...but I sure wish I had gotten the 30amp model!

    I can imagine. I hit the 40A limit on my PL6 today. I joked with a friend about needing a bigger charger. I think 60A would be sweet. My 24V PSU was only pushing 15+ amps.
    So I guess I could just get another PL6...
    I don't get how the $50, 50-watt battery cooker guys do it. (Nor why, but that's a different topic altogether.)

    Postage for 2 x 8200mah 2S lipos to Western Australia = $105.

    Yep postage is $5 more than the cost of the two batteries!

    I would still buy them at that cost. I have priced other lipos of approx the same mah at LHS here in the states and they were $90 to $100 a piece. These are really good batteries, you wont regret buying them. I ran with my grandsons over the weekend along a train track, we walked an hour out and an hour back and I was only down to 3.6 volts, probably could have gone another 20 mins or so. I wonder what happens to the shipping price if you buy more. Maybe there are some other Aussie's that would help with the shipping and spread the cost.

    The last set of batteries I bought for my grandsons summit vxl, there was 8 one dollar bills and 65 cents in the package. The freight was less than paid for so he refunded my money. Tom did not need to do that and I would have never noticed. Honesty is hard to find any more. When I need batteries is SPC, even if I have to wait.

    $370 is too much for me to charge batteries. I just got a $119 Onyx 245 and it charges them in about 45 minutes.

    8.2 Amp-Hr / 5 Amp = 1.6 Hr or 1 Hr & 38 Min and this does not take into account the CV portion of the charge cycle. So in reality expect charge times approaching 2 hours if the packs are near empty.

    Edit: This is not a support-type post, but rather a simple math fact regarding charge times.

    I know that with my Hitec x4 it charges at a rate of 6 amps maximum and from storage mode at 3.8 volts it takes abut 45 to 60 minutes to fully charge the 8200mah batteries. It takes a little longer than an hour and a half to fully charge from 3.4 volts when the batteries have been fully discharged. So your Math formula is correct in my case.

    THERE BACK!!!!

    But there's only 18 left. Its amazing how the spc 8200 and the smc 9400 come in stock at the same time

    I "donated" a great pair of spc 8200 to my friend, so this time I purchased a set of smc 9400. Now the wait begins

    I tried ordering one yesterday. It said they were in stock and let me add it to the cart. But once I tried to check out, it said they weren't in stock. Sadness.

    I'm almost positive they are still in stock. I suggest you call them. They're really nice!

    I had this same problem last night but I can confirm that the problem seems to be fixed. I ordered two this morning.
