Wow....5000 cycles, true 60C rating and priced a little too high....I can't fall for BS marketing and big corp. like practices, specially in a hobby. Have any of you guys wonder why they don't go for the Aircraft guys? Here's a hint....Most newcomers to the hobby will always get started with a rc car and will read the rc magazines and fall for the marketing first before finding out there are similar packs out there at less the half the price.

I wonder when MA will leave the rc hobby and move on to the military and/or auto industry with their incredible cells. The owner of MA also has other ventures going for him, so he should be ok when they can't sell anymore over priced packs. Apogee made the move to supply the military with their cells and I haven't seen any being used or reported by the military.

That's a very good point Lutach. Aircraft folks generally know what they are doing.

The majority of newbs to RC get a traxxas because it has ridiculous speed claims on the box and the shiniest packaging. They then hop on the net and see a Maxamps advert and end up on the site seeing yet more shiny advertising and speed claims and before they know it they've dropped $200 too much for tat.

My sister's boyfriend bought an E-revo and then bought a set of Maxamps pack for it. I went skits. Now he is well versed in the arts of lipo and brushless and the truck is full of NEU, Castle, Spektrum and RC-Monster products.

Odd that Maxamps aren't so hot on boat and aircraft packs. Considering the fact they have the best products in the industry you'd have thought that everyone with high amp boat and aircraft setups would be all over that shit. :lol:

"Well, these batteries should last for 5000 cycles so for them to have died at 500 you must have abused them"

Baseline is, you are paying a massive premium for a guarantee that means nothing in the real world.

Even if these Turnigy Lifepo4 cells aren't the same or slightly lower quality than the Maxamps cells, is it worth paying a $140 premium for a 3s2p 4500 pack that MAY last a few more cycles. The answer is no. It is not.

I would be willing to bet they are the SAME cells.

Conducted testing here and the results were good, on the cheaper cells.

I haven't been able to justify giving the amount requested to test against the "competition". There's nothing wrong or misleading about the Turnigy Lifepo4 packs.

The "Competition" is full of BS, and hoping to line their pockets. Just my opinion. :yes:

True, and if any other company had Lifepo4 cells that fit the Mini Revo I would have been all over them like a rash.

Noone did.

I ran my 2 2s 8000 Maxamps packs in one of my boats, they got a little warm but worked fine. Funny thing is that by using them I INCREASED the load on the motor which increased ESC and battery temps. With Maxamps I had to use such heavy lipos to get the amps I needed that it weighed the boat down causing it to run VERY hard on the water which builds more load.

<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/E82kX9Vio4o&hl=en_US&fs=1&"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/E82kX9Vio4o&hl=en_US&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object>

Drop a pound of weight off that boat and it would've ridden on the very last inch or two of the hull rather than have 2/3 of it still in the water. I know NOBODY that runs Maxamps in their planes, boats, or helis though. Rhino packs, yes, but no Maxamps...that's sad.

Thanks, they're a ton of fun! Lots more complicated than a truck though. Lots more to go wrong and when things do go wrong you'd better be prepared to retrieve it. I have an inflatable raft and electric air pump I keep in my car for when things go wrong. When everything comes together and works as it should, it beats the pants off bashing a truck!

But how often have things gone wrong? I've always wondered what happens when it flips over or hits something and starts getting water in. Just kiss your expensive electronics goodbye? I really want a boat (very similar to the one Hippie just bought actually) but the whole thought of it sinking isn't to pleasant...

I would say form factor. I've got the Turnigy packs and I don't think the volume they take up (even if rearranged) could be squeezed info a hard case the size of the typical ROAR legal pack.

Cool beans- I wonder if MA will drop the prices on their Life packs, or will they just say ' protek am factory rejects' like they did with the Turnigy cells? :lol:

Thats great news. What a great sales pitch though. If you buy our item you are getting the best for your money, but if you buy anyone elses crap you are buying rejected items that the factory sold them for cheap. That should be the new sales ads for Ford Motor Company. Don't buy anything but Ford or you are buying reject automobiles, and you will be subjected to recalls or accidents.:rofl::whistle::rofl::whistle::rofl:

Boats flip all the time, it happens mostly from turning faster than the boat can handle or hitting chop going too fast. The hardware at the keel it usually attached tight enough that water doesn't come in through the holes, the stuffing tube is packed with grease which helps keep water out, and you are supposed to tape the hatch down so the hull is basically an air chamber which keeps itself afloat. This Spring I'm going to start taping the hatch, in that video I didn't have it taped and despite the busted up bow I would have been able to go in after it before it sank if it didn't take on so much water through the hatch.
