Hi Guys,

I'm looking at buying a couple of these for a Slash. Any feedback?

http://www.rcbazaar.com/products/1745-wolfpack-2200mah-35c-74v.aspx

Ignore the mah. The link is only to show you the product.

I intend to use it till I can get better Lipos shipped in or bought locally. In the meanwhile Gandhar is helping me scout for a good quality Lipo. But I'd like to keep the wolfpack option open because its easily available locally.

P.S - These are not the wolfpack sold by reedy. No idea who manufactures these. RCbazaar didn't seem to have a clue when I called.

Looking forward to your feedback.

Thanks!

a few obvious questions that come to my mind are:-

(a) is 35C enough for car, burst 40C too seems inadequate
(b) are these Chinese batt actually 35C as claimed ?
(c) i have a wolf Pack, its internal resistance is higher than Zippy and much higher than nanotech
(d) Surprisingly, Indpower batt of RCDhamaka has the least internal resistance, lesser than the nanotechs that i have (I have more than 15 nanotechs)

anyone has contrary experience please share

The stock Lipo provided by Traxxas is rated for 25C. My plan is to run two lipos in parrallel. Which should theoretically double the C rating. But as you mentioned, its a good idea to take these ratings with a pinch of salt, especially since this is a cheap chinese model. But I'm guessing with two in parrallel, I should atleast have 40C constant. I may be way off target though

Also I'm not going to be running full throttle. I've had my savage for a long while now and its never seen a full throttle!

I looked at Indpower too. But 2S is not in stock. My only option there is to run two 3S 3300mah 20C in parrallel. But I really dont want 3S speeds.

I'm mainly looking at durability and decent run-times.

Where do you usually buy your batteries? Shipped in or hand carried? Suggest me a good place to order. I'm leaning towards hobbieking or amain. What do you suggest?

Thanks a ton for replying!

You can avoid the 3s speeds by setting the Throttle EPA appropriately

I don't think the stock esc supports fine tuning, or does it? I thought the only option was training mode which just limits throttle to 50%

The EPA is an adjustment you make on your Tx.

You're on the right path, not taking C ratings seriously. Yes, a 20C lipo has lesser punch than a 40C lipo BUT a 150C lipo is not a 150C lipo.

@Rajath: I advised against 3s because the stock power system is not very comfortable on 3s. It would require re-gearing and the VXL-3s does not have the greatest reputation running on 3s.

Oh ok.. I wasn't aware the stock radio had EPA adjustments. I know this is a long shot - but does the stock esc have punch control? I don't want 3s to shred the powertrain. Or is the slipper my only option?

One of the main reasons I want to go parallel is so that I can maintain a decent C rating.

The VXL-3s has no punch control. The best punch control is your throttle finger.

EPA is an easy way to limit power and is an available on nearly all modern radios. I'm sure your radio has it.

My finger's been known to have a mind of its own! If only it was as dependable and responsible as punch control :p

The HPI Tx has dual rate and trim controls. No EPA. So I assumed its not there on the traxxas as well. I'm guessing between EPA and Training mode, I should be able to find a sweet spot for 3S. However if wolfpack is as good as indpower, I should be able to find a good 2S setup..

I'd follow rcpilotacro's suggestion and wait for the Ind power packs. The 5200 mah 2s 40C I saw at RCD were pretty good. If you get them, let us know how they work out.

I guess I'll do that. The prices are almost the same as well.

If I'm not mistaken, the Ind power packs were around INR 2200, right?

The 3S 5200mah 20C costs Rs.2156. I'm thinking along the lines of 2 X 2S 2200mah 20C. Currently 2200 is the maximum capacity listed for 2S.

But none of this is available. The only remotely suitable one available is 3S 3300mah 20C.

When did he say he'd get the 5200mAh 2s 40C ones? I'd wait for them.

Hi All,

I've been using the WolfPack 4200mah 35C pack for a week now and its held up pretty well.

Run times are in the vicinity of 30-35min. Don't have exact run times but it gives me around 1.5 hours worth of bashing fun. This includes full throttle runs, jumps, hard braking, time spent on roof etc.

I'll check the IR and post it here later on.

Also, it barely climbs above ambient temperature. (Measured, not guessed.) The motor and ESC stay at 130F and 100-120F respectively.

Its done 4 cycles and so far so good. Will keep updating this thread with new findings.

It might have been a bad peice, but i had a 3S Wolfpack die in only 2 weeks, in only 4-5 cycles (one cell went dead, not holding charge).

dheeraj..not sure if you are aware... there is a 2 months replace warranty on all wolfpack batteries.. if you have any issues pls write back to send the lipo back with your order...

yes this might be a bad piece as we have had some great feedback from our customers on this batteries...

Hi Sujju,

I bought this pack long back, and though service from RcBazaar has been nothing short of excellent, but in this occasion i was told that there is no warranty on LiPo, so i just let it go. I am till buying from RcBazaar

pls do return the lipo... and a new one will be sent to you.. we will state this on our website too about the warranty as it will help all this ambiguity... 

sujju

Thanks Sujju, will do.

Hi Sujju,

Its nice of you to clear the confusion. I think the staff at the store should be made aware of this as well. They made it clear to me that there is no warranty on Wolfpack products. Lipo or Chargers for that matter. It was the main reason I bought only the basic charger and one battery.

Can you confirm if the chargers have warranty? I am looking to buy a decent charger (b6sac) and the warranty is the only thing that puts me off.

Thanks!

Tassem.

I bought a 2S 4200 mah 35C lipo and the B6sac charger from RCBazzar about a month back. Been running it on the revenge since 2 weeks. The battery must have run for about 8 cycles till now. Have had no issues. The run time on the revenge is good. About 40 mins( approximate  guess) with a good amount of full throttle. The charger is also good with no issues till now.

I have been using the wolfpack 2200 mah pack in series for quite some time now with my hiller 500 great batteries have had no problems at all .....it may sound funny but 2200 20c pack provided a good punch  for a 500

Thanks for chiming in guys. The wolfpack I have (2S 30C 4200) is going strong with about 10 cycles on it so far.

If it continues to perform, I have no doubt I'll be getting more!

Taseem... Where do you run your vehicle in bangalore?
