Flux MMM on 18C batteries fine according to SMC?!
 

Either im full of misinformation or this guy is a disaster waiting to happen. Doesn't HPI AND Castle Creations state that a 25C rating is a minimum safe requirement to power the MMM without having to worry about power flucuations that could fry it? Either this guy is misinformed, SMC's has poorly informed rep thats giving people incorrect information or I'm missing something here.

I have sent the following email to SMC directly and I will post here so everyone is informed of what is currently being done about this.


Dear SMC,

It has come to my attention as well as many other Flux owners that very possibly one of your associates is spreading VERY misleading and inaccurate information about the battery requirements in regards to HPI's Savage Flux, particularly the MMM ESC created and provided by Castle Creations. It has been stated both via the HPI Flux manual and Castle Creations president that the MMM will work best and most reliably with battery systems that are able to provide 120 continuous amps which equates to a rating of 25C or above on Lipo batteries. Castle themselves have stated that lower rated and or quality batteries severely risks power spikes and fluctuations that can easily destroy the MMM ESC. I would like further details and investigation into this as already many peoples Flux's MMM's have died as a result of poor battery choices and having your associates giving MORE false information is going to lead to Castle and HPI have some VERY angry customers.

I am currently running your 6000mAH 28C Lipo hard cased Sport MAX batteries on my Savage Flux and they are doing very well and im very impressed with the run time and power they provide my truck. Being my first brushless RC as well as Lipo usage, my initial impression of your products is very high. However, I will not tolerate a company that gives false and misleading information that results in peoples products being damaged and destroyed and I ask on behalf of me and MANY other brushless RC trucks for an inquiry into this.

Sincerely,

The amount of FALSE and MISLEADING information thats being spread around via uninformed peeps is killing Flux's left and right AND IT HAS GOT TO STOP!

I have also sent the following email to HPI directly and will inquire via phone in a few days in regards to a response from them.

Dear HPI

The following is a copy of an email sent to SMC batteries in regards to a VERY large issue with peoples Flux's MMM ESC's dying as result of poor quality Lipo batteries. We have Castle Creations stating that their MMM ESC product works best on 25C or above rated batteries which can provide at least 120 continuous amps to prevent damage to the MMM from power flucuations and spikes. Castle Creations has stated that your suggesting that the Flux can be powered via NIMH also contradicts completely with what the Castle president has stated in the following threads.

Your company has obligations to give us consumers that purchase YOUR PRODUCTS the BEST and MOST ACCURATE information possible for us to run our products that will give them long life and reliability. We ask that you provide publicly announced and provided UP TO DATE details in regards to what BOTH YOU AND CASTLE CREATIONS agree upon on which batteries and specific battery ratings will work best win the Savage Flux RC trucks and the equipment that powers them.

Thank your your time.

25c is not really relevant it is about support of continous amp draw - Run the 18C packs in parrallel and you'd be fine.

:whistle::sleep:

The "C" rating isn't the number to go by. With 18C if the pack is 6500mAH or better then you're all set. You could run a 15C 8000mAH pack if you wanted to.

What's_nitro?, I love the new avatar! I can't stand Oprah myself.

Are you sure you understand the concept of "C"? You got the part about 120amps continuous correct, but that has almost nothing to do with "25C". The ONLY 25C battery capable of 120amps continuous exactly is going to be composed of 4800mAh cells.

Now, that 120amps continuous figure is good. In order to reach that goal with an 18C battery, you need a capacity of at least 6700mAh (where that pack is rated 18C).

"C" is SO misunderstood and completely overrated. You can have a 40C 2000mah pack but it's not gonna do any good in a MT, "even though it's 40C". However, that pack could work if there are about 10 cells in series :intello:

Thanks TSP!
