I'd also suggest our smaller 2.4ghz mini remote. It's pretty awesome and no drop outs.

Put it this way, a 30 W soldering iron is hot right? You wouldn't want to grab it, and when 1500 W comes out of your heat gun, girlfriends blow dryer, that's a crazy amount of energy, right?
You are trying to harness all that power, wirelessly, and vibrating heavily, so if it's a bad design or wiring, mayhem will occur. Your car esc will probably break 1st though. I see no evidence the vesc is unreliable. YMMV.

Ok, I will look into the VESC again. Would this be an acceptable charger or would the charge time be very long compared to another that is only 10-15$ more? http://www.hobbyking.com/hobbyking/store/__76462__IMAX_B6_AC_DC_Charger_5A_50W_With_US_Plug_Copy_.html

If you are serious about lipo charging, i would go to an iCharger. I have one of the non "copy" (clone) Imax b6ac v2's. Good little slow charger. Your limitation is charge time since you are maxed at 5Amps.
(here is a bunch of good "parallel" charging info)
Let's compare setups. If you have 4 5000mAh 3s 20c batteries (pretty decent and commonly used batteries). Their max charge rate is 2C (10A = 5000mAh x 2C).
Simply charging one 5000mAh lipo @1C will max out your 5A limit on the iMax B6AC and take about 1h 15min. (x4 for all your packs = 5 hours before you are ready to roll again). Charging at 2C would be 10A for one battery and about 40min to full (harder on battery life so most recommend 1C Max or less to maximize battery life). BUT having the option to hammer in some amps to get riding NOW vs later is a great option! IMO. 2C isn't possible w/ the iMax B6AC w/ those packs. Let alone other lipos now that can charge at 5/8/more C! Not how i charge normally - but great option to have in a hurry!!
Multiple packs charging at the same time is where you start to save tons of time. So those same 4 5000mAh 3s batteries using a parallel charging board w/ a decent charger - instead of 5 hours individually, you can charge them all in 1:15, but would need a charger that can do 20A (5A ea), with a DC power supply that can provide minimum of 315w.
Slower is honestly better for the batteries. Folks recommend different charge rates - if i have time i usually use .5C.
Here are some calculators to figure out charge times and power required (both Amps and Power supply requirements).
Simple charge time calculator
Parallel charge calculator w/ power supply requirements.
My overbuilt setup is an iCharger 308, with dual 750/1500w Dell server power supplies (12v and 24v in series) with max load of 50-60A iirc. If you look at the voltage supplied to charger you will see how higher voltage is more efficient (in second calculator). The iCharger limit is 30A, and the parallel board i have is 40A limited as well. Overbuilt like i said.
A good iCharger (or similar) charger is worth the investment if you are serious about charging lipo's. (and other chemistries). Add in a decent AC/DC power supply - any of the hobbyking 350/500w ones, or a nicer dedicated one will probably cost you about the same as a dell server power supply w/ 2-3x the capacity. Just louder w/ server fans and some additional wiring complexity (also = flexibility). I charge via two chargers off same set of power supplies sometimes at the same time.
Tons and tons of ways to do this. My way isn't the best or easiest way by far. But shows options.
HTH - GL!

You can use 350W or 550W HobbyKing Power Charger.
IMO 350W Power Supply for $40 or 540W for $65 is fairly cheap for a put together power supply. Beats having to wire your own computer power supply and a much smaller form factor/portable.

Also, get the VESC. it can directly interface with the Kama / nunchuck, and you save $25 since you don't need a wiiceiver.
LEVer said:It can go no more than 10s, but will work with less than 10s. Even nominal 10s, which is 37 volts, is not the max. Your battery pack's voltage is much higher than that fresh off the charger.
Relaxnfly said:Yes lever...thank you for the clarification. It is a challenge to weed through some of the misinformation.
Bbcane- If you order the HK 350w power supply, you have to get the one that is appropriate to your power outlet. I live in the US and have 120v at the outlets in my garage....so that's the one I ordered. The 220/240 would not have worked for me.
Relaxnfly said:If you want more power....connect in series for increased voltage. If you want more capacity( bigger gas tank) ...connect your bateries in parellel. I suggest you do some additional reading and research.
Cheers

I am now thinking a 10,000 9S2P battery (2 9S1P 5A/h) but I am having trouble finding a decent charger for up to 10S batteries, I am putting the 9S batteries together with 3 3S batteries so I don't even know how the pins would work with a balancing cable. Are there other cables on the batteries I can use to charge them, and does anyone know of any 10S chargers that won't cost a fortune.
I had originally planned on only using 4 3S1P batteries and connection them as a 10,000 6S2P. And I would have charged it with 2 of these, http://www.hobbyking.com/hobbyking/store/__10993__Twin_pack_charge_lead_2_x_3S_6S_w_XT60.html
Would that work/ would i be able to do the same thing with using the batteries as 9S? I wouldnt think so because id have to connect two batteries balancers and the batteries are already in series in two different parallel parts. If this would still work and I could just charge the two 9S batteries as 3 6S batteries with a normal 6S charger? Or would I have to unwire each of the batteries from 9S to make them 2 6S batteries and connect the two 3S batteries removed from each 9S together, then charge them.
