Yeah Racing HARD Case 4000mAh 25C 7.4v Lipo
 

New Yeah Racing HARD Case 4000mAh 25C 7.4v Lipo. Coming Soon!

I have been using one for a month now and love it. Actually loaned it to a top notch driver last night and he was impressed with it. I went to Yeah Racing's web site this morning and it is not listed but on RC-mart they show it is on backorder. I hope that it is not discontinued.
If you can, get one!!

These are the new 4000mAh packs from Yeah, Ultraline imports yeah racing products here in the States and will have them in-stock soon.

SWEET!!
Buy them up guys!

Both On-Road and Oval guys love the 3200mAh and 3600mAh from Yeah Racing now its time for the off-Road guys to chime in.

XXXT Mamba Max with 4600kv, offroad.
Like I said earlyer, I love my 4000, strong start to finish.

slap some1 elses sticker on it who is buddy buddy with roar and u'll be legal too. that or pay near double just to be 'roar legal'

I would be scared to buy a lipo from some one like yeah racing as they can some times cheap out on quality

Glad your happy w/your 4000
You might be surprised, the quality of these packs are outstanding.:nod:

What are the dimensions of the battery?

Thanks.

When will these packs be state side? I'd love to get one, I just dont like pre paying for something as I know how shipments tend to be delayed on things.

Should have more info in the next couple days.
They are on the way, we should receive them early next week. We did add them to the site for those that would like to pre-order.

If these packs are anything like the 3200's I will be inline to buy some.

I have about 25 charges on my 3200mah packs and they are still performing great. I tested them when new and again last week, they still look great, with a 20amps discharge/ 6.45 Volt cutoff they give up about 3250mah and the IR is just 1 or 2 #s higher than my trakpower 4900's. (All done on a tekin DIS350 discharger)

These packs have to be closer to 3600 from my testing

Running in my stock slash at the track I can feel no differance between the yeahs and the trakpowers packs and the performance with a MM 5700 combo is awesome to say the least.

I will also give props to ultraline,

First off free shipping was something I did not expect but much appeciated.
I was even more surprised after I saw the packing job, batteries were in a 12x12x10 priority mail box with a ton of packing material, + each battery is packed in a box with a double layer of bubble wrap. There was no way USPS could damage these batts. I have ordered soft packs that only came in a baggie and a padded envelope!

Thanks Yeah Racing for the great packs and thanks ultraline for the great price and service.

One question for ultraline, is the wire still 10Ga? and in the picture I can't see a balancing plug, Hope there is one and that it is the popular JST/ALIGN plug?

Thank You for your support, after 20 years in the business its always great to hear from our customers.

New photo of the battery shows the plug and wire a little better.

How exciting! Cant wait to see how many more companies can slap their stickers on this one too.
