I am curious to see if anyone has tried these. The price is good, but how do they perform, and how much capacity do they actually have?

I'm leary of these ultra-high "C" ratings. I seriously doubt the battery can live up to those claims. All these cells are made in China, and all China is about is mass production. IF cells were actually as powerful as some manufacturers claim, we'd all be running them.

It's been proven over and over that to obtain output with thise ultra-inflated C ratings is almost impossible given the physical size of the packs.

However, they still may be very good packs, it's just those high C ratings are just too high to be real.

If you try one, please post back and let us know so others may also enjoy a reasonably priced LiPo battery.

I would go with a name brand lipo , with a more practical rating .

I know the folks personally, whom run the Barn. I will back them 110%, they are very good people and operate one of the best facilities here in the North East. That said, I've never heard of these batteries so I can't offer an opinion. Although, I did post a link to this thread on theirs, located in the Racing forum, so hopefully one of them can offer more insight.

I have one in my 22t.a 5 minute race leaves the pack at 8volts running a 13.5 motor. Charge it about 5 times a night twice a week. No issues/no problems. The Ir is 6.

I ordered one, should have it by wed. I will put it through a cycle to check its capacity an IR. I will report back....

I'm running their shorty packs in a mid motor 22SCT running a RevTech 17.5 and Tekin RS speedo. So far they've performed admirably (since December) and I charge each packe about 3-4 times per practice night.

I'm running their shorty packs in a mid motor 22SCT running a RevTech 17.5 and Tekin RS speedo. I run on a small indoor carpet track. So far they've performed admirably (since December) and I charge each packe about 3-4 times per practice night. They work, time will tell how reliable they are, but no issues to report so far.

IR is 6? Isn't that very high for Internal Resistance?

Just curious, why would you charge a pack 5 times a night?

1. Show up charge

2. Post practice charge

3. 1st qual charge

4. 2nd qual charge

5. 3rd qual charge.

Sometimes i charge more than that.

That is high IR, my old nano 6600 reads lower than that. You should see those numbers in a good saddle, not a good stick.

My 7200 smc is reading 1.7 & 1.8.
Reedy 6500 comes in at 2.4 & 2.6.

Both with about 15 cycles on them, maybe auto's are older packs... guess I could see those numbers after a year of use.

The low IR race packs from smc are a fantastic deal, 6500 & 7200.

Hey Guys,

Thanks for your questions and inputs. We have been testing these batteries for almost a year now and have had great results, so we decided to begin importing and selling them.

Since we purchase them direct from the factory, the price point is much lower than the name brand packs. A name brand battery will pass from the factory to the manufacturer (Reedy, Trinity) to the supplier (Great Planes, Horizon) to the hobby shop and then to you the consumer. By purchasing directly, we cut out 2 levels of pricing markup. So this is why the batteries are such a bargain.

As for capacity, we have tested many of the batteries and found them to be quite reliable. For example, the 7200mah battery consistently charges from 3.2V per cell to 4.2V per cell at 7150-7300mah.

For power output C-Rating, we have not done any extensive testing due to the fact that we do not know a way to accurately measure this. If anyone has any ideas, please let me know.

But, we have tested them against other battery packs to try to 'feel' the difference in power, if any. We ran three batteries in a Losi SCTE for 4 weekends of racing. The SCTE is equipped with a Tekin RX8 and Novak 4.5 550 motor. The batteries used were a Reedy 6500 65C, a Turnigy NanoTech 6600 65C, and the Vant 6000 80C. The Vant consistently felt more punchy than the Turnigy Nanotech. It also felt equal to the Reedy.

Also keep in mind that the 6000mAh 80C battery has been inspected by and has passed ROAR's LiPo requirements. Another vendor of these battery packs has also had the 4000mAh Shorty pack approved by them as well.

The batteries also come with a great 6-month warranty through us.

Any other comments or findings, please post! We are quite interested in seeing results of these Vant batteries in real use situations.

Kind Regards,
Chris

We have also had a handful of reviews on our website for these batteries. They are all real reviews from actual customers :-)
