I mean i bet 95% of us here would never buy a MA pack anyway, and i am sure they know that. I havent looked but i bet brandon and/or jason is much more active on the traxxas forums, RCU, RCTech etc than they are here on RCM because that is where their target demograpgic is.

I am not active on other forums. Marketing Director for MaxAmps.com is a full-time job, so I just don't have time to be on the forums chatting away. With that said I am making an effort to get some things together and hopefully the videos will completed shortly and well as some other tests that I would like to share with you guys. You know, it's like one big MaxAmps.com party in here. So enjoy the weekend guys and I will get some stuff to you shortly.

The cool thing is that you have the power to turn it all around. I'm sure there are a few who will never forgive/forget, but the majority of us are just looking for the best battery we can get for our money spent.

I got burned by several early MA packs, so I haven't purchased more MA packs since. I still have purchased chargers, wire, shrink, etc from MA though.

Bring a pack as good as a Hyperion for a similar price, and I would be willing to take another chance on MA again. The way you are keeping your cool in this environment is truly impressive.

Waiting patiently for more info ... thanks!

Hi Brandon-
Will the graphs be ready for posting soon? I'm very much looking forward to seeing these graphs. I'm very interested in buying a set of these batteries. I'm just waiting to see your graphs first. Please post any and all data you've been working on regarding these specific model LiPo. ie Graphs, Videos and so on- all of which you have said you would post as soon as you had the time to do so. I would also like to say that you are very professional on this forum. I do hope you will continue to post information as it becomes available to you- onto this thread. I've been eagerly waiting for these graphs and videos you have been working on- and sure hope you can find the time to get these test complete and posted for us- we are all very interested.

PS. I can hardly wait to see the 75amp continuous discharge of this model LiPo. This data alone will show extreme ability.

Note: I had convert my E-Revo to a Brushless E-Revo with the same motor and esc which Traxxas uses in their model- it's the Mamba Monster Electronic Speed Control and the 2200kv Castle Creations Motor.

I was running two 5000mah 3cell 40c continuous 80c Burst Thunder Power LiPo's in series to make a 6cell LiPo- which is what the motor and esc are designed to handle as a maximum voltage. I was doing high speed wheelies through the park and the truck had enough power to pull the front wheels up at apx 50miles per hour. Testing revealed that none of the temperatures were excessive, the motor and esc stayed under 150 degrees, batteries stayed under 110degrees. Gearing was per castle creations tech support suggestions- as well as the setup of the esc.

Running the E-Revo at various different parks or even in a parking lot- is primarily where I run this model RC. I consider this my Basher RC but I don't really jump it or crash it hard- I just pull high speed wheelies and like to go as fast as possible from zero to top speed of this model. Both castle creations tech support and Thunder Power tech support told me this will be fine and the system I have will handle this aggressive driving. After a few runs at the park under the same conditions- I notice the lipos began to puff(only apx 30cycles) And not at any specific time. In other words- they slowly puffed a little more and a little more and the puffing did not go down. I called Thunder Power and they told me I was overdischarging the lipos. I told them I have the LiPo cutoff set to 3.5volts per cell and that I do not run the truck to the point of LiPo cutoff. Jim of Thunder Power explain to me that the motor can also overdischarge the batteries by pulling to many amps. I then called castle creations and they confirm that this system only draws 125amps max. And a 40c continuous LiPo well exceeds this. I called Thunder Power back and they explain in great detail that 1/8th scale buggy is the hardest class of RC on batteries. And that They have to send a new set of lipos to their team drivers about every three months, consistantly. And that lipos raced in 1/8th scale hardly ever last beyond 7 months because of the severe conditions.

I was quite shocked to hear all this because I had thought Thunder Power lipos to be among the best lipos made. And knowing that these lipos by thunder power are under a one year warranty- and Jim telling me that these lipos rarely if ever last 7months- made me wonder why they were not offering to replace my less than 1year old thunder power lipos. In fact- this seem to qualify anyone running 1/8th scale for a warranty replacement after 7months of use(Jim assured me that this goes for all high end LiPo's). I called castle creation tech support and they said it sound like the batteries could not handle the 125amp continuous amp draw I was pulling from the batteries when I would pull a full speed wheelie across the entire field of the park- which could very well take about 5 to 10 seconds at full throttle, or full 125amps continuous, or as castle tech support said- apx 100amps continuous. I imagine MaxAmps is aware that 80% of the RC industry is support by non racers- and people that never go to a track. But rather buy an RC and race it up and down their street(often at full throttle). I happen to do both. I race 1/8th scale buggy which I agree those burst amps are useful to know. But in consideration of the 80% of what these batteries may very well be used for- which is wide open full speed ahead- how fast can I go for how long- those continuous amps sure come in handy. I don't think it hurts to show both the continuous amps and the burst amps. The more information we buyers have access to is the more informed we are. And information on the product is something every racer and basher can appreciate. As for my E-Revo, I've not run it ever sense I found out the batteries could not handle the wide open full speed across the entire park- runs I was doing. I can't tell you how many people would run over to me and ask me where they could buy one of these. And how many dogs chase my RC as well. Many people said they would buy one just to give their pets exercise chasing the RC :)

Note: Brandon- do you think based on the information I provide- I could run 2 6500mah 3cell 150c lipos(in series= one six cell)in my Brushless E-Revo wide open across the entire park which is about the length of three football fields length wise? Without puffing the LiPo's? I've modified the battery boxes so the 3cell 6500mah lipos will fit right in. I just need to know if you think these lipos can handle apx 125amps being drawn from them over the course of apx ten seconds, and then turn around and do it again and again until the lipos are at the 3.5volt per cell LiPo cutoff point- or just before the LiPo cutoff kicks in? Thank you Brandon. I very much look forward to your response.

Yes our 150C packs can handle the load. We have tested them at a higher amp draw then that.

Well. Well.

Where've you been Brandon?

It's kinda funny that you "show up" when some "proof in the pudding" is on the table.

IMO, it's too bad that it wasn't you, that offered real world graphs up, like you said you would do.

You might have won some respect here.

[MindThoughts]

Awesome, Thank You Brandon.
I truly appreciate your continuing to post onto this thread. I know the forum owner has asked a few times for members to keep their post civil. And I certainly respect Monster Mikes Forum :)

PS. I'm looking forward to your data, test & graphs and videos. Any information on these race lipos will be extremely valuable and interesting to see and learn about. Thank you for being so open about doing this for us. I've never heard of Thunder Power doing any test for us racers, and those are also quite expensive lipos, and I personally would like to give other lipos a try- such as these 6500mah. The way I see it, if your Lipos can compete with the Thunder Power LiPo(Thunder Power Does not yet offer a 75c continuous Battery) I would rather go with the MaxAmps LiPo because I get a warranty. Whereas Thunder Powers warranty is not as flexible. For example- With a Thunder Power LiPo- for the first two years of ownership- we qualify for a 50% crash replacement. Which means we pay 1/2the new cost of the same battery. That is primarily for crash damaged batteries but Thunder Power can decide if they wish to allow a customer to have access to this crash replacement discount if it is determined by Thunder Power that the lipos were overdischarged or otherwise damaged by the owner of the lipos.

MaxAmps warranty- I've not read it in awhile but now comes standard with all lipos. It's a 3year 300cycle warranty and I believe within the first year it is a free replacement, and then a percentage added for use for the remaining two years depending upon how long the battery has been owned/used. MaxAmps has also lowered their prices allot- and removed there reduced price program which only gave the big spenders huge discounts. Now those discounts are applied to all the batteries. And I really like that move- great job MaxAmps- Well Done :)

Note: I recently purchased a 2500mah 2cell LiPo for my M11x and I asked Jason if he could make me one because at the time- they only offered the 3cell variety for the M11, whereas the newer model M11x takes a 2cell LiPo. Jason said no problem- he made the lipo and even add an additional wire for 5c quick charging- because MaxAmps uses the 5c quick charge cells for Transmitters as well. This means ten minute 12.5amp balanced charge times- and the LiPo only went up apx ten degrees from ambient/room temperature.

If these 6500mah MaxAmp LiPo's are competitive with the equivalent Thunder Power LiPo- the way I see it- the cool looking design on the MaxAmps batteries is just a plus. Most batteries have very little- if any design. And though the design on a battery has nothing to do with performance- I think MaxAmps is doing everything they can do- to satisfy the customer. And now that I think about it- I've never met anyone in person that has run or is running MaxAmps- that has anything bad to say about the batteries. And this is one of the reasons I highly recommend these batteries to my friends and family. Not one of us has ever had a problem that we feel MaxAmps didn't go out of their way to help us with. Even if it meant returning the battery within 30days for a full refund. That's MaxAmps. I don't know of any other battery supplier that offers anything near this kind of satisfaction guarantee.

I can also understand that paying allot of money for batteries is not possible for everyone. And for those of you that wish to pay very little for a LiPo- there is Hobby King with their Turnigy Line Of LiPo's- and many people run those and are very happy as well. Even though sometimes you will get a bad battery. The price is so low, it's still less to buy another one. I will also be giving the Turnigy cells a test this new race year as well. And I'll do a full review of the Turnigy cells vs the MaxAmp cells vs the Thunder Power cells. Thank You For Reading.
