Trinity Revtech Formula X Shorty 2S 100C Hardcase LiPo Battery-7.4V/5000mAh

Update Apr 24, 2015: AMAIN IS AMAZING! After many emails between Trinity and Amain, the problem was resolved no thanks to Trinity. Amain went above and beyond to solve the probelm at their own expense. I can happily say, with Amain's dedication to customer service, my problem-battery has turned into another great experience with the best hobby shop in the country. I look forward to continuing my business with Amain. I still don't recommend Trinity RC products. I DO highly recommend Amain Hobbies, you know that you can trust Amain to solve a problem the first time!

Mar 16 2015: DON'T BUY TRINITY RC PRODUCTS. Trinity has terrible customer service.I'll start with the good. This battery has great punch and limited battery fade. That's all the good there is. The bad is overwhelming. When it arrived, it would not balance. I have a Hitec X2 charger. When I say it wouldn't balance, I mean it. After over an hour of charging to put in 1500mah, it would not do better than 4.21v and 4.12v. The worst part is their customer service. To send the battery in for warranty, the instructions INCLUDED with the battery say, "You must email, not call, first on all battery warranty issues. Describe your issue along with pictures of the battery pack in question & sales receipt. Any battery returned for repair without first sending in pictures and receipt will be disposed of with no notice to sender." I did just that, and this is what Anthony at Trinity said back to me, "You have to follow the instructions in the box for warranty. Fill out all the information and send battery in." All of his emails were disrespectful and rude. It is sad that Anthony, one of the founders of the company (I think) does not even know his own warranty program. Please do not buy Trinity products. I can not say that enough. If you get a good battery, maybe you'll be happy. But if anything goes wrong, don't expect Trinity do help you in anyway. For $110, I should get a battery that works. If it doesn't work, then I should get a little customer service and some respect. Goodbye Trinity. One more customer lost. -TK RC

update on the last review battery was good till 7-8 months of usage when it went BAD was reading low voltage cell what a waste of money for that much money you expect this to last a while not few months never again buying this crap avoid at all cost !!!!!!!

After about 12 cycles on the battery, the case puffed and will not balance charge or discharge in a reasonable amount of time.. was a good battery for the 3 race days that i was able to use it..

I will not be ordering another one of these. I purchased one at the beginning of January. The case did not line up with metal plugs in the battery. The first time I plugged it in the case cracked. Trinity said to send it to them and they would send me another. Just last night the new one arrived nearly a month after sending the first one in. This one the negative terminal is so out of line that a plug will only go in about 1/4 of an inch. Trinity wants me to send this one back and they will send me another one. I think I am done with trinity stuff. Not once was there an apology for the delays or even an explanation. They told me one had shipped and when I asked for tracking info I got it 3 days later when they actually shipped the replacement and did not even check for defects before it left their ship.
Save your money

An edit after reading the review above. The guy above said that he felt like the emails from trinity were disrespectful. I felt the same way. Every time we talked on the phone or email I received was as if I was a bother to them.

Terrible Packs, Purchased 3, Used them all twice, ALL 3 PUFFED!!!!!
Do Not recommend at all,
No support from REVTECH after 30days, Terrible SERVICE!!!

POS. i should havejust stayed with Orion. after 1 run in my xray xb4 the case cracked and puffed alittle bit. I didnt even crash to make the case crack. I called trinity to get the info about sending it in and they were so rude I just counted my lose and didnt even send it in. I rather throw this in the trash then send it in and get a new one so people can see me running there ShLt. never againn Trinity, in fact Ill bash the company any chanc i get by just telling the truth. how about getting someone who cares to answer the phone

Amazing is the bottom line.

Cells came super unbalanced, Trinity said to cycle them a few times.

I did so and they balanced perfectly by the 3rd cycle, and they're explosive.

TONS of punch, and super consistent. In a 6 minute race, they slightly fall off around the 5 minute mark, but blow the protek shorty pack I picked up.,

I will definitely be ordering a couple more of these.

Awesome battery, with a lot of punch. Using it my TLR 22 2.0. I have the RevTech saddle pack as well and performs great!
