I Love my MaxAmps Lipos for my Summit.
Best Lipos i have and will order again soon.
I tell everyone about them and they can't believe how fast and how long the summit runs.
Thank you!

I purchased 2 for my Traxxas Summit. Awesome power, and they last way longer than any lipos previously purchased. Great batteries for a lifetime!

I'm very new to the RC world, but when I asked which batteries to get for my axial yeti XL the answer was hands down the max amps. I have used them several times and have always gotten close to an hour of run time no matter how hard I bash! I would recommend them to anyone.

These batteries are simply Amazing! I can't believe the runtime and the torque is AWESOME! I fully charged and balanced the batteries for my Traxxas Summit and literally ran the truck so much and got bored, it was pouring down rain, the ditches had about a foot-and-a-half of water in them and I can tell you that the batteries are 100% waterproof no issues at all. When I was finished running the Summit I checked the voltage and battery percentage of each pack and the battery packs still had 65% life remaining on them! That is what I expect for the price I paid, they are worth it. I then checked the balance on both of the packs and they were perfectly balanced after my run. I then put them away for storage since the packs are supposed to have 60 to 70% charge remaining when put up for storage. Look I know everyone likes their money and these batteries are not cheap, but this is one of those times where you really do get what you pay for. Just go ahead and buy the MAXAMPS batteries you won't be disappointed!!

Best batteries ever

- May 05th 2016

I bought a pair of maxamps batteries for my traxxas summit. The truck is big and heavy and drained the stock batteries in about 7 minutes. The max amp batteries just keep going and going. They have great torque and more punch. They are worth every penny. I will be buying maxamps for every ex I own!!!

this battery is the power output through my savage.anyhow better change the clutch first because this battery got yummy juice!thumbs up!

Just the best on the market.

- February 21st 2016

Simply put, best batteries on the market. The price point is on par for the value. I won't buy any other battery from here on out, I have never had an issue with any of my three sets of batteries so I can't speak about customer service or the warranty, but I would guess it's as good or better than the product.

Best batteries.

Not one complaint. They are great

I'm still in love with these batteries after years of my use of them. They just out perform any other brand on the market. The cost is high, but at a 100C they are powerful.


- August 18th 2015

You simply cant go wrong with these batteries, they last forever, charge perfect, been using then for a month now an Im very pleased, I've bought other batteries before, but I would have to buy 4 of them to even come close to these 2, Max Amp only battery I will ever buy. I can do backflips from a dead stop with ease, no more 3 cells for me, these are perfect.... 100c burst with well over an hour run time, Im usually done with the truck b4 the batteries die.

Second Max Amps Battery

- July 12th 2015

This is the second battery I've bought from Max Amps. Very pleased. Longest running time and fastest charge I've ever seen. I can't wait to try the 6s next!

Exceptional Battery

- June 24th 2015

Perfect fit for the E-Revo. Keeps it going right at 1 hour. Exceptional performance. I loved it so much I had to get a second one.

Hi just to let you know thee's battery s are great I bought the 7.4 battery's & charger 2 mounths ago the service was great got the in a week to Australia and they run great.

Hands down this pack is the best pack I own. I get 50 min run time in my Slash 2wd and it packs a punch like no other brand. A friend of mine tried it in his Slash 2wd and he said this pack by far is better than any pack he has tried. The consistency and amount of power is awesome!!!

I will try to make this short. Bought this product. Got it fast although I live n Germany. Ran 5 CHarges with my Savage Flux HP by now and it runs more than an hour now. After five charges the charger from my local dealer just exploded so I won't be running any more charges soon but I am lookng forward to it, since these LiPos are just awesome.
Kind regards, Fabian

So far no problems. I believe you get what you pay for and that's Quality. I have run these batteries close to an hour in my Summit. I've made 3 separate runs in the snow so most of the time its full throttle and I'm running dual 700 brushed motors! I have about the same money in 4 lipos which last 15min a pair. You do the math and Buy Maxamps!

- March 12th 2015

These batteries are long lasting ,power they are everything you want and need in batteries. there's no other batteries , I'm going to buy again

Just a thank you note for your thank you note. You folks are the greatest! Great products, great website, great customer service. Here's wishing you and your company the best.

Excellent product. Tons of run time between charges. Super fast 5C charging. Quality built pack. I bought these to run in my Traxxas Slash. I discovered while converting my Losi 8 to brushless that they also fit perfectly in the tray for that conversion. I use 2 packs with a series connector for a 4S pack. They will also fit nicely in the new Traxxas Titan. A good all around battery. It's great having just one pack that will fit in many vehicles. Maxamps customer service can't be beat either.
