From what you've said you're running one battery, correct? That does make a difference, but, most quals are 5 min. (at least where I race) I can easily get both quals in IF they do 3 quals, I can also get the 3rd qual in on one charge.

I would definitely have a full pack for the main, but, all those chargers are going to cut down on the life of your battery.

Having 2 batteries (of like or similar specs) would be a good invesment IMHO. Personally, I take 4 batteries just 'coz I like to play with different ones. And playing is what I'm all about with my RCs.

Very interesting stuff Chris. Wish I had known about these before :P

Do you institute a 2s restriction at Da Barn for 4w Mod SC?
I'm thinking those 3s + Pro4 3300 would be dialed! :sneaky:

Any chance of you getting any 4s or even 6s ( which I prefer to run in 1/8 ) batteries?
Thx for the time, and credit for the av pic too ;)

I can say that they are QUICK to get stuff out in the mail, I ordered on Sunday night, it shipped out Monday morning and is out for delivery today!

I'll post my initial results when I put my first cycle through them.....

I got my pack and did a full charge at 12 amps, then a discharge to 3.2v per cell at 10amps and the battery discharged approximately 6900mah. Not bad at all. After cycling it a few times the IR was on par with my 3 month old revtech 6900mah 100c battery.(It was cool out so the IR was not accurate) Initially, it is defiantly a good pack, but time will tell how fast or slow the cells degrade, but I am satisfied.

Hey Rob,

Generally people run only 2S of course. If 3S on a 3300 is about the same speed, then I don't see it being a huge issue among the racers. The 4600 on 7.4V calculates to about 34000RPM, where the 3300 on 11.1 calculates to about 36000RPM. I agree though that higher voltage is more efficient.

I do plan to get some 4S packs in when spring hits. I don't plan on getting any 6S packs though :-) Sorry.

Great news! Let me know what you find as you use them more.

I bought a 6200mah 2s 60c Vant lipo one thing i like is that the bullet connecters for the hardest fit nice and snug into the lipo . Ive only ran my a few times so its not quite broken in yet so i cant exactly judge it yet.

And my backup charger i had to use is only a 50w and charges to 5.0 amps im waiting for my new charger to come in the mail that goes up to 6amps.

But after a few charges the cells are equaltly balanced same when storeing them . So its a better quality low price lipo :nod:

Well i had about 6 cycles on this lipo and i dont know if its because im geared lowed and my motor runs cool . But man these lipos have some punch no drop off into a 8 min main ! And the cells stay really balanced run after run and the Bullet connecters on the wire hardness are pretty good and tight !

For $45.00 for a 6200mah 60c 2s lipo its
pretty good.

They have lower MAH rating 2s lipos also in them and have good C ratings.

I would take a look at these lipos !

Thank you for the post. I'm glad to know the Vant LiPo Batteries are meeting your racing expectations. :)

What charger are you getting these IR values. I believe you are using a different rating. I have never had a Lipo show an IR rating lower that 3 or 4 on my Hyperion. My Thunder Power and Hyperion packs show anywhere from 3 to 8. My SMC packs show around 15. I think your 1.7 to 1.8 is 17 to 18 on the Hyperion. I know that Auto2 uses the same charger that I do. A rating of 6 on my Hyperion is great. I will be getting a 4s pack to try out myself and will report back.

Picking up 2 Vant Batteries for ROAR Nationals at LCRC. Is there only one of your batteries ROAR approved???

That's great! Yes, only one is currently ROAR Approved.

Just got mine in the Mail on Tuesday. Ran them last time. Just as good of a pack as anything else i've ran. (revtech, reedy, turnigy, crc). We'll see how long they last, but I'm satisfied with the 2 4000mah shorty packs i Purchased from DirtcheapRc.com.
